I heard and experienced problems with the K12.2 only ... I've heard the pre-.2 amp cards and K8.2 and K10.2 are good as far as parts failing in the amp cards. We had two K12.2s replaced before we had a good pair that didn't go into limp mode after 30 mins of program.
Tried this very system after watching your viedeo because band member called raving about how sweet this system sounded , found your review and watched and yes pre set up for gig in band room they sounded very very good we were loaned the system and were considering switching to it , long story short played a Saturday night festival with them and 3 other groups during second group one shut down another time one gave damadge warning , only left with monitor sound till for some reason they settled down and resumed working , to many unsure reason , i wont kick any money in for the system , very disappointed I was truly hoping after initially listening to the sound we wouldnt have the issues youve alerted us to Thank you for your honest sharing
Make sure you use the K.2 updater and update your speakers. The USB input is behind the main knob. I check mine for updates often. Have four 12.2 and four ks212c and no problems.
I’m curious about these updates; why would you need to update a speaker? I play music full-time for a living as a solo LoopingArtist using multiple instruments, including bass guitar. One of my tops went out a year ago, and I have been lazy about doing anything about it, because I had another powered speaker I would just use, and now the other QSC top blew out. I am on their website looking for a service center, and when I enter my city, it just keeps searching, but nothing comes up. So I will call Sweet Water tomorrow to find out what’s up.
@@davidbrucemusicvideoI was renting my QSC Speaker and out of 4 Bass Bottoms only 1 of them is working right now. Out of 10 QSC Tops only 4 is working. 2 of my Tops need to be updated cause after 20 or 30 minutes the sound turns off. One of my Bass Bottoms was blown out because these new DJ’s always turning the music up to loud and the volumes be in the Red in Distortion Mode🤦🏽♂️😳 After I get all these speakers fix I’m not Renting them out no more and I might sell some of them to lol
@@djblvdrodd dammm i have all qsc.. is extremely hard to blow those honestly… I destroyed one high frequency driver because I unintentionally screwed the factory eq settings, sending the bass to the highs, iam not kidding, the actual resonance material was in pieces… The k12 woofer didn’t blow either, it just got kind of stuck on the same position for some reason..
Rule number 1 is to never hang powered speakers, unless you can easily reach them and monitor them.. Also never turn the knobs up to the max, like most sound guys would do.. Newer speakers should be leveled after you eq you mixer and sound sources.. I’ve had my pair since they were 1st introduced in 2017.. Only issue I had was with the extension cord power source not sitting snugged within the sockets.. That also includes the use of the locking power cable provided by the manufacturer.. The power must be snugged..
Same here. I have issues with two of my K12s, one of my KW152s and one of my KS118s. Never had an issue prior to Covid but it seems like I’ve keep running into issues with the gear that I’ve bought since then.
This might be why QSC’s wood cabinet KW line still uses the original amp from the original K series… the KW122s sound better than the plastic cabinets but it is a little bigger and heavier. Their PLD amp line (now discontinued) had some issues so I’m in the process of selling those off for my mains. They have been great for monitors though. Also have KS118, K12, K10.2, and the KW122s I mentioned. Never had a problem with any of those, but I do agree that since Covid hit, their company is a little bit more hit or miss than before. The PLD amp line came out around 2013 though and wasn’t their best and what I’m used to. The PL380 amplifier is bulletproof though, but has no built in DSP. I feel like their R&D is more focused on active powered speakers and Qsys networking tech these days more than amplifiers despite being an amplifier company first and foremost.
Purchased both speakers QSC K12.2 and ALTO TS312 on 02/14/2022 Played 20 gigs, with the QSC K12.2 on the right side and the Alto ts312 on the left side of the front-end PA system, and on 09/30/2023 the 20th gig, the QSC failed to work, it would power up, but would not process the signal from the PA board. Trying to get it fixed now by warranty....
I've owned a pair of K12.2s for almost a year now and use them with my band probably about 3-4 times a month. Sometimes I experience sound cutting out or dropouts but that was due to my faulty Presonus Studiolive 32R that I had serviced and now works like a charm. I do feel like there are certainly more reliability issues with this model compared to the K series of old. Knocking on wood, because when they work, they are brilliant sounding speakers.
I’ve had the same experience with my K12.2 speakers, one of them shutting down in the middle of a performance at least in three different occasions. When this happened I asked one of my band mates closer to the speaker to turn it off and do a reset. Feel very uncomfortable when using them. Both speakers have the latest firmware version.
I own a pair of Electro Voice ELX 200 12P with the matching 18 Inch Sub and man does this sound system blow me away with how great this sounds. I've owned my ELX 200 12P's for roughly 6 months now and recently bought my subwoofer less than a month ago and they have been great to me so far!! I like my music loud and I push them to the limits and when I'm DJing I would often times check and see if the speakers are getting hot and they perform just like you expect them to!! Please be aware that I've owned speakers from JBL Eon, Mackie, Carvin, and subwoofers strictly from Cerwin Vega and the EV's have the been the best sounding system I've ever owned.
I have 2 12.2's and k118 sub. I use them for band gigs. I feel like these are more for that. DJ's go especially hard. Those 3 speakers are absolute bangers at shows. It is unreal how loud a band can get with them. They all stay at 0db, sometimes outdoors I will pump the sub 10-15 percent over. All this being said, I am about 8 months into my purchase and you're scaring me bro lol. I have been looking into buying a pair of the 8.2's for monitors. I can say that I am close enough to sweetwater to drive and pick up purchases like this. It never sits right to have such expensive gear delivered to me. delivery people are so overwhelmed I just don't trust them to handle with care anymore.
It's not just you, and not just bad luck. I had the exact same experience with a K8.2 that I was using as a floor monitor. Got some feedback during a performance, muted it within 2 seconds but the amp was fried. It was only 8 months old so still under warranty. Took it to an authorized shop. It took 8 months to get a replacement amplifier. Like you, my confidence was shaken in what I'd always considered a premium brand. Unlike you, I cannot afford to replace all of my QSC speakers so I'm kinda stuck with them. But you better believe I'm really careful about feedback now. Who knew that you could kill a speaker due to a software problem?
Had my K12.2 in 2020 or 2021 and a little less than a year it just cut off during a NYE gig. No power, won’t turn on at all. So yeah I’m scared to get another. Sticking with my EVs however I’m itching to get the KS118 Sub
Love my first generation Pioneer XPRS 10” mains, Baltic birch-55-20k hz-134spl-Powersoft amp 90x60 degree angle. Only drawback is there are 41lbs for a 10” speaker which is slightly heavier than I want. Considering replacing the LF driver with a neodymium to lighten up the weight
Got a K.2 10 for a monitor and has shut off on me twice at gigs. Been back and forward selling it, but this video sealed it for me. I just ordered the Everse 8 to use for gigs.
Thank you so much for the vid. I had the same issue with my k12.2. I was djing a high school event and wasn't pushing them hard at all and they shut down. Luckily they went back on after resetting them. I thought it was a fluke but it did it again at another event but this time it shut down completely. Sent it back to QSC and they sent me a replacement. I can't trust K12.2's any longer so I sold them. I miss my legacy k12's. I switched over to RCF's and love them!
@@MrMaui38 It's scary to think that this would happen to such a reputable speaker. I was very disappointed. RCF's are the way to go. They're simple and sound great!
@@jasong.3985 Exactly! I was so surprised and disappointed after how many QSC products I’ve seen used by other DJs, and how many good things I’ve heard. When I called QSC service center back then, they said that they were expecting a recall for the new amp modules that had started going out post Covid.
Very surprised by these stories. I've installed 3 sets of dot 2s in the 3 venues, and never had problem with any of them. I also own 2 pairs that have been hammered since they came out, and never an issue.
I had a brand new K12.2 die on me last summer, only 1 year old and used for maybe 15 events. The amp module was bad, they released a few bad batches I guess. I got it fixed under warranty, pretty bummed though. I''ll probably keep that one and sell my other 2x other road dog k12.2's.
I run two show locations that use 6 k12.2 each (12 in total) 4-5 shows a week. Over the past 2 years we’ve had to send 5 amps to get repaired/ replaced. Mind you we don’t run super hot signals through these speakers(never in the red) I also know others that send almost 1 k12.2 a year to go get replaced/ repaired. Build Quality is definitely not the MOST reliable but they sound so damn good. I do think most of the damage was caused by rain and sea breeze though, only other incident I’ve had with a k.2 series is when they are in hot weather they go into protect mode. Definitely invest in a solid way to protect these speakers from the elements.
I have been living with Protect Mode 4 on two K10.2s that I bought in 2021. Due to Covid, I didn't use them much until this year. I've now had 4 outages with one speaker and 5 with the other. I use these as either light duty mains or as monitors. Firmware is updated to the newest version 1.3.3. I sent the speakers back to Thomann for waranty service - all they did was update the firmware and send them back. I've got a case open with QSC, and I have seen a service bulletin that indicates that a hardware fix needs to be made. I'm hopeful that QSC can make this right, because right now I can't trust these speakers. My old K12s were absolute tanks, but these things are currently too delicate. My hope is that QSC can swap out the amps and I'll be good to go, but for now I'm far too scared to take these to a gig.
Thank you for making this!!! I bought two brand new 12.2 last year whos amps shut down middle of my gig last year…twice! I returned them immediately and went with rcf. Extremely disappointing and I’m glad to know I’m not the only one with issues!
@@devere9675 I didn’t try that before returning them so can’t say if that would have fixed it. I did call QSC service center who did not mention that either. They were brand new out of the box so I would assume they had the latest firmware.
@@francoisblanc6453 I bought the RCF HDM45 which are bigger so may not be a good choice for you if you’re looking at the 8.2 or 10.2. I had the issue with the 12.2, so I wonder if the 8.2 or 10.2 would be okay? The RCF HD10 or 910 is a good option if you’re looking at 10 inch speakers but I’m not sure of any comparable 8 inch options to the 8.2
bom vídeo...eu tenho um par dessas caixas k10.2 e uma delas ja entrou em proteção ...acredito que foi queda de energia ...depois do reparo na autorizada veio atualizada o firmeware ,atualizei a outra caixa também...uso elas constantemente volume no máximo em 0 ou 1+ db as vezes com Sub k212c ...nunca usei estabilizador de voltagem (((recomendam)))Mas confesso que também perdi a confiabilidade!!!e o modelo K" antigo não tinha esse problema!!
Well I got both legacy and the k.2s no problems this far but that’s for the info I did the firmware update. I’m not sure what it did but K.2s still work🤞🏾
I purchased the KS118 as soon as they dropped in 2020...both woofer blew on gig #2...The official QSC dealer said my serial numbers fell just outside the range of serial numbers they were looking for.....after that I felt kind of uneasy about them so I sold them and started back using my KW181...which I can turn up louder with no issues ...Unlike the KS118's the limit light started coming shortly after turning on the speakers and especially if you turn the gain to the 1 oclock position on the amp. I have the original K12's and KW181's I bought since 2017...no issue ever.
That’s the crazy thing, the original K-series (KW181, k12, etc) were so reliable and so good that it’s surprising the new ones have as many problems as they do. I bought a pair of original k12s :)
I’ve been considering the K10.2 bit this is worrying to hear. I notice on QSC’s website that all the .2 range had a new chipset revision from 5th Sept 2022. There has also been subsequent firmware updates for this new chipset and I’m wondering if any of the recent issues had these new chipsets running the firmware 1.5.5 version? I’m also considering the EV ELX200-10p as I’ve read a number of reviews say they prefer them to the QSC’s though I had reliability issues with the original ELX Line-X range.
I remember when the k.2 series came out. I was all set to upgrade from the legacy series I own but just never heard much of a sonic upgrade. If anything, the new K.2 series didn’t sound as full and had more background hiss. I have stuck with my original K12s which sound fantastic.
I bought 2 K8.2s. Love the sound. Never push them hard. The (all my gear) looks new. 3 years+ in - one stopped dead @ a gig -no sound. Luckily I have 3 yrs left on the ext. warranty. I did update the firmware. Just shocked. think I'll go back to using my crown amp with a pre and power 2 QSC E110s. Amp module suspect. QSC factory did apologize via email and will fix it but...possible 2-3 months wait. Hmmm.
Issues galore with the K10.2s K12.2s have been absolutely flawless, as have the KS212c subs. I'm not a DJ though. Sound guy, this is my mobile small gig rig.
I just bought a pair of QSC K10.2. My current dealer has confirmed to me that with the new firmware 1.5.5 the problem has been corrected. Well I hope so - what do you think?
What many people don't realize with self-powered speakers = a speaker (especially a subwoofer) is a VERY harsh environment for an amplifier/electronics to live in. Think about the pounding, rattling, shaking, vibration that the amp is subjected to while in use. I am not saying this was the cause of your failures, but I've been in the business 35+ years and by comparison, I have never had a power amp (rack mount 19") ever fail - across thousands of uses and installs. IME passive speakers powered by external amps are far more reliable. The world's greatest speaker systems are passive and powered by external amps (d&b, L'Acoustics, Adamson, Danley, JBL VTX etc.). I have tons of powered speakers, don't get me wrong - but seriously considering going back to all passive for the above noted reason, plus not having to run power all over a stage and venue. Side Note: I installed (6) KLA's in an auditorium (2015 I believe) and (2) amps died within 3 months. Manufacturers need to get back to a focus on reliability. If a speaker doesn't work, it doesn't matter how good it sounds.
this does not make sense as original K series did not had the issue which had all the things. Most likely this is quality control issue with parts in amp or design issue.
I have a K12.2 that failed at a gig for no reason. It just cut out and all the input lights stayed on even though no source was plugged in. Took it in to an authorized QSC repair shop and they said something on the amp failed and that it was an ongoing issue with the .2 Series speakers. I paid almost $400 for the repair. I’ve only had the speaker for about 5 years so I thought it was still under the 6 year warranty. The problem is I never registered none of my QSC speakers that I have so basically it voided out the 6 year warranty and made it a 3 year warranty instead. That’s my fault for not registering the speakers within 30 days of purchasing them.
Same thing happened to me 😮 It happened to me several times at some important events. I was totally embarrassed. I ended up selling 4 of them because I couldn’t trust them. I had the original k12 for over 8 years with no issues
The k.2 series has a flaw in the design for the amp and has a recall but they are only replacing the amps as they go out. I run a pair of k 8.2's and have had both amps replaced and have had no issues since. These were installed in 2018 and both amps replaced by end of 2019 no questions asked.
I thought I was the only one who felt this way! I've had reliability issues with my K10.2 speakers and my KS118. The amps fry so easily and a woofer blew out on the KS118. I have 4 amps sitting in my house that I have replaced. I do not recommend these speakers anymore for this reason.
@@gatchmanphoenix1418 Yeah. I did recommend them after I first got them. That was what... 2 years or so ago? My opinion has changed now. QSC really lacks in the reliability area. That's been my experience.
question - do you think the k.2 issues are the type that, if they're gonna happen, they happen right away? e.g. if I buy used ones with multiple years of reliable performance, would you expect that they're past the window of potential issues?
Burned over 6 of my k12.2, so I sold all 8 & bought 4 KLAs. Kept all my KW & K series subs & tops. The analog boards don't have to worry about the DSP chip malfunction. The new series use a 2ohm ceramic speaker instead of 8ohm, cheap dsp chips and warranty is useless if they can't keep up the supply of parts!! Hopefully the new L array series doesn't disappoint but then again.. its digital as well..
Do you think an Everse 12 would sound significantly worse than a k.12.2? ... I want a speaker with a battery and I'm torn between buying an everse 8 for around town or selling my k.12.2 to buy everse 12... around town would be acoustic guitar and vocals, but my use case for k.12 at home is a power amp for my electric guitar modelers and simultaneously playing practice tracks... would I miss the QSC at home if I went with one everse 12 speaker for everything?
The original/"legacy" K series from QSC is still great. I now use (and recommend) BassBoss DiaMon 112s and RCF TT10A's. Both are under 30lbs and get stupid loud. The DiaMon is a coaxial speaker so that has some benefits, while the RCFTT10A gets incredibly loud and can network with the rest of the RCF life. I am lazy so I like the lighter weight. My "bigger" mains are Fulcrum FA22ac's which are the best sounding speakers I've ever heard period. They weigh 60lbs though so they can be a pain in the ass to get on stands. They're also discontinued :(
Well what the peak spl level when ppl are having issues? Or are the using a powered mixer /DJ mixer on already powered speakers? Not sure why feedback would shut it down but maybe it’s a safeguard when ppl aren’t doing things right type thing... not sure. Two yrs into mine but I don’t need to go super loud.
That was the weird thing. I’m so paranoid I make sure there are no limit lights on or anything. The feedback wasn’t super loud; I’m just surprised it fried the whole amp (if it was too much power drawn, it should have just blown the fuse). It’s a puzzle for sure
I had 2 qsc k12.2s go off at the same time on two occasions and have had them break more times than all my 22 qsc k series speakers combined.i agree with you these are very sensitive and are bad for 220v regions even with the firmware updates.
Im a Dj but new to hosting outdoor raves. What speakers do you recomend ? Now looking at the Mackie DRM 15" active speakers and 18" DRM subs. What do you recomend for Techno music ?
After 2020 QSC reliability is not the same. I have a pair of original 12.2s work great ( purchased new in early 2019) - i purchased a second pair of 12.2s in 2022 (that's when I started having problems - mostly shutting off randomly).
I have just been given one to repair K12.2 i think. It is under warranty but the other one also had issues and it took him one month to get it back From Thomann. He uses it on a ski mountain so the next month Feb March is important. Can't be waiting one month again! So, they shut down after 3 seconds then reboots and shuts down again in this endless loop. I'll be opening it up in the next few days to have a look. But 2 units still under warranty both broke! I could not work with this. Imagine i turn up for a €1000 wedding with those! Personally i'll stick with my RCF or my V15 Tannoys and use the Martin Audio for the bigger events. I do use some QSC gear. I have some power amplifiers which have mostly been ok but the 6kw Powerlight (PL6) died unexpectedly and my first repair failed the power supply mosfets are super expensive! I have a CX404 which is not too bad but the volume pots could be better. The PL236 seems ok but the PL4 has an earth hum on one side which i find surprising. It's not enough to notice with music on so for now i'm not bothering to open it. I guess the older stuff was made better but doesn't last forever without expensive servicing.
I have 4 K10.2s..Two of them stay at home. two of them i bought from rental and are lugged around for PA uses.. Theyve broken down on me a couple of times. I wont get into it right now (maybe slowly over time) but i wont recommend QSC either, for multi reasons. One quick one is an 8 month wait for a small part and then only to be told its not made any longer....also: Try calling them and see how THAT works out for ya. They got my money, no need to answer the phone....i guess i own them for better or worse at this point, and unless i feel like spending another 1500-2K , ill just have to use them. Where on the presets is the best place to start for guitar reproductions? for instance as an frfr for Helix, Kemper whatever. Thanks for the vid and giving us a platform to obtain information. That alone gets you a thumb up here! EDIT: also gotta wonder which input for guitar? Looking thru the manual, it seems as if input A bypasses the preamp of the K10, and B does NOT!
I bought my K12.2s in fall 2020. I bought my KS118 in summer 2021. I use them weekly at my live blues venue. Never had a problem and I've never updated them. Is this because of when I bought them? Maybe the shutdown problems started with the same speakers after the ones I purchased? I keep hearing about the quality of parts in the amps. The amp modules are blowing because of inferior parts and not the design. Perhaps the Covid epidemic had an impact on getting quality parts because of supply chain issues? QSC doesn't say or acknowledge this. That's why people are mostly pissed off. From what I know, the amp modules need to have certain parts replaced. A lot of repair techs have been saying that.
As a rental/production house we own over 20 K and K.2 first K series no problem whatsoever. One fan died on me in 10yrs. K.2 two amps died in the first 6 months. Same use same events. QSC replaced the amps with warranty quickly. I am on board with you on reliability and so on. EV speakers match and in some cases surpass the quality. JBL is always a good buy. Price is also a problem as well. They behave like Apple in some cases. Still have my K12s and they work without problems. TBH we do use EV Evlove 50 now more than the QSC on a lot of corporate events
Yours isn't unique, but I was told that the firmware update ... supposingly cured the issues - I'm yet to get surprised?? I've managed to solve issues with re-initialization ... but I'm not satisfied with doing it during soundcheck.
I’ve had bad luck with my K10.2s and K12.2s! Amp problems, argued with me at length that I didn’t fill out my warranty on time so no warranties for me. I like them but I make sure I bring at least 1 extra top in case 1 stops working. I keep my trailer humidity controlled at 50%. They’re in cushioned cases. Never pushed near max. Always have large subs with them. And have them surge protected via higher end Furmans FWIW. Aside from QSC K2 stuff I’ve only blown 2 woofers in 33Ys! If they’d even offered to sent 1 or 2 amps I’d have been happy, but nada. The amps are easy to very easy to replace….
I used to work for a rental company as a technician, it’s true we did have some K.2 who burned out but it was all before the software update, now it’s working like it should for a QSC product. I’m even looking to get a pair of K10.2 myself
I almost pulled the trigger on these until 4 straight days of researching after seeing your video and for the price you pay for QSC, it's not worth the headaches. The K12s are rock solid but the 12.2 produced during and after the pandemic has an uncomfortable failure rate that no professional band or DJ want's to encounter which is very sad because I've heard these and thought they were perfect for the type of music I play at events. Now I'm down to JBL PRX912 or RCF 912A. The only thing I didn't like about the RCF 912A is they don't have the DSP, but the one thing I love about them is plug n' play. Has anyone else had better luck with K12.2 manufactured after 2023?
I had one completely fry and the other fail and then somewhat work tonight at a worship event. And they weren’t being pushed very hard at all. I am beyond sick right now…
I have the original K12 speakers and I still think that they sound better than the K.2 series. They can handle the load better. You can really push them to their limits and still sound amazing
you had a lousy experience bro I know how that feels but my Qsc is in perfect condition after 4 years of use. I do weddings for over 400-500 people with two EV exks subs and great sound.
I own 7 K10.2s. I've had two of the amp sections completely shut down. However, both speakers (out of warrantee), were quickly repaired and have been working consistently since. 2 out of 7 is not a good reliabilty percentage. However, good news, they were quickly, easily and economically repaired. The service (Triple S Electronics) was amazingly quick and sent a full analysis of the unit's performance. What other brand can be serviced like that? Stuff breaks for whatever reason. I want to know that things can be repaired, that's almost as important as how reliable they are. When I've tried to have Mackie, Yamaha or EV units repaired, I was on my own. Not so with QSC. Also... in my opinion, the K.2 series sounds A LOT better than the K series.
What was the issue you had with the amps? It sounds like the amps themselves weren’t completely broken, but rather it was something small where they didn’t need to be completely replaced
I bought a pair of Alto TS415’s. Years ago I had TS315’s and returned them rt away because they just sounded weird. Since Alto replaced those and added more power all I can say is wow! QSC watch out because Alto is competing directly with y’all at a much more cost effective price.
I just got two of them, fingers crossed. My question is I notice some white noise even when there’s no inputs. It’s not major but not sure if it’s normal?
Yeah that’s normal, it should be pretty quiet though. With gain staging you should be able to adjust how much there is-see if when nothing is plugged in whether you still get the noise and if it changes based on the volume knobs (even with nothing plugged in)
I have a friend of mine who does sound and he cranks the knob 100%.. He must use a digital mixer at all times to cut out the ringing feedback.. Meanwhile Im using a dj mixer running 4 mics at times with no white noise or feedback.. Maybe He thinks these speaker’s operate like his old passive systems.. 🤷🏾♂️

Mine cut out on the first performance after buying new ones. Yuck. I would trade them in for legacy K speakers. Thoughts on preferred speakers a year??? Thanks
Dang that is so frustrating. For lightweight mains I now use (and recommend) BassBoss DiaMon 112s and RCF TT10A's. Both are under 30lbs and get stupid loud. The DiaMon is a coaxial speaker so that has some benefits, while the RCFTT10A gets incredibly loud and can network with the rest of the RCF life.
@@djmyr Today I traded in my k12.2 for legacy k12 off my experience with the older ones my boss has. Never an issue. I'm probably the only one trading in old for new & am stoked for it too! Your video definitely helped me pick a lane before more of my gigs occur! I'll give an update in the next few weeks fingers are crossed!
@@Highvibesociety. Nice. I recently bought another pair of K12s (the original) about a year and a half ago. Zero problems and I use and rent them out them all the time. It's a good purchase
I have another QSC speaker that just went out, my KS112 Subwoofer. Took it out to a small gig I had yesterday paired with a K8.2 and it wasn’t working. I’m having the same problem that I had with my K12.2, the green signal light illuminated even though there was nothing plugged into the speaker. I bet it’s the amp that went out again. This is totally unacceptable QSC.
EV ETX, JBL SRX, BassBoss, or RCF would be my top pics (in no particular order). The JBL SRX stuff never let me down, the subs in particular were very impressive. The ETX stuff sounds great, and RCF and BassBoss have great reputations for a reason (BassBoss has an unbelievable warranty). Yamaha DZR too but Ive heard some problems about the DXS18XLF. Finally Mackie DRM really impressed me for the money. You can always buy a pair of used “legacy k” like the k12s, those speakers are amazing
Have you thought about the Mackie SRM450v3 1000W 12-inch Powered Speaker or even smaller SRM 350v3, which I love as I pair them with the original QSC K12 series running my 4 tops of Mackie/QSC SRM 350v3 10-inch blows the competition away even the CP8s are on stand by with my collection of the QSC/SRM series of speakers front of the house, You are correct I do not like the K.2 series!
I believe something was wrong with your speakers or the setup you were running. I have k12.2's since 2019 and never had an issue. Even the issue that a lot of people were having that the speaker stopped working and needed a power cycle became of a faulty limiter security feature. Regardless, I've done all the firmware updates for the k12.2 available online and updatable via USB cable into the speaker from a pc. And it never had that issue
The majority of the problems are coming from speakers manufactured in 2021/2022 during the supply chain debacle. QSC started using crap components from China because they couldn't get their regular components. Now there is a trust issue with QSC. The company is very good at honoring their warranty.... but some of us are actually using these speakers to make a living and can't afford to risk losing gigs because of unreliability.
Good morning ! after 5 years of use of QSC k12.2 I have never had a problem! I pushed them to the limit multiple times for hours with no problem. these are the best speakers i have had. apart from a slight vibration of one of the k12.2 at high volume nothing abnormal. still working day after day. some feedback and nothing to explode. I am in canada therefore, with the 120volt and not 220volt sockets. I do believe it does! they seem sensitive to 220volt despite software updates. have a good day! thanks for the video !
I have 10 K12 and 10 KW 122 when they came out with those speakers I didn't like them because they have to many settings .. The old ones you just put the cord in and turn them up !!!!!! AND THEY WORK
Yorkville is a damn good speaker it’s all made in-house except the speakers inside but they use Italian made b&c drivers The amp board is not made in china it made by yorkville . Qsc make great amps but the powered speakers are not as good. Piece of advice if you installing any speakers get a drive rack pa and set it up so you won’t destroy your speakers
I bought a pair of K12.2s in January 2024. Used them on 2 gigs and they sounded great. On the third gig one of them died. I checked the firmware, and it was up to date. I asked around and another band told me they had the exact same problem. The tech guy at the QSC authorized service center told me in confidence that he is constantly getting K2 speakers in with the same problem, and he explained that the ones with power modules from China have incredibly high failure rates. The wait time on replacement modules can run well over a month. Yes, QSC will repair or replace them when they fail.... but that won't help me when I'm on a gig and they die. If you are a working professional musician, you can't afford unreliable equipment. I'm done with QSC for now. It's a shame, they sound great.... but being unreliable is a deal breaker.
I have allll RCF sound but lucked up and snatched 4 of the legacy K12’s only because I got em all for $800 from a guy who always goes for the shiny “new” gear and sells everything. I already had a pair that I kept to rent/backup and of course now dude is on DJ forums complaining about his k.2’s and how he hates he sold his old ones (& I keep my mouth shut cause I’m not selling them back ever) 😂
Dang, going on five years, three gigs a week, all sorts of weather and the K8.2 and K12.’s still going strong
Hoping your good luck continues 😊
Pre 2020 perhaps
I heard and experienced problems with the K12.2 only ... I've heard the pre-.2 amp cards and K8.2 and K10.2 are good as far as parts failing in the amp cards. We had two K12.2s replaced before we had a good pair that didn't go into limp mode after 30 mins of program.
Mines as well. They’ve been great to me
I too have had no problems after 2 yrs .
I've had my K12.2s for 8 years now. 4 or 5 gigs a week, no protective covers and they still sound as good as day one.
Tried this very system after watching your viedeo because band member called raving about how sweet this system sounded , found your review and watched and yes pre set up for gig in band room they sounded very very good we were loaned the system and were considering switching to it , long story short played a Saturday night festival with them and 3 other groups during second group one shut down another time one gave damadge warning , only left with monitor sound till for some reason they settled down and resumed working , to many unsure reason , i wont kick any money in for the system , very disappointed
I was truly hoping after initially listening to the sound we wouldnt have the issues youve alerted us to
Thank you for your honest sharing
Make sure you use the K.2 updater and update your speakers. The USB input is behind the main knob. I check mine for updates often. Have four 12.2 and four ks212c and no problems.
I’m curious about these updates; why would you need to update a speaker? I play music full-time for a living as a solo LoopingArtist using multiple instruments, including bass guitar.
One of my tops went out a year ago, and I have been lazy about doing anything about it, because I had another powered speaker I would just use, and now the other QSC top blew out.
I am on their website looking for a service center, and when I enter my city, it just keeps searching, but nothing comes up. So I will call Sweet Water tomorrow to find out what’s up.
@@davidbrucemusicvideoI was renting my QSC Speaker and out of 4 Bass Bottoms only 1 of them is working right now. Out of 10 QSC Tops only 4 is working. 2 of my Tops need to be updated cause after 20 or 30 minutes the sound turns off. One of my Bass Bottoms was blown out because these new DJ’s always turning the music up to loud and the volumes be in the Red in Distortion Mode🤦🏽♂️😳 After I get all these speakers fix I’m not Renting them out no more and I might sell some of them to lol
@@djblvdrodd dammm i have all qsc.. is extremely hard to blow those honestly…
I destroyed one high frequency driver because I unintentionally screwed the factory eq settings, sending the bass to the highs, iam not kidding, the actual resonance material was in pieces…
The k12 woofer didn’t blow either, it just got kind of stuck on the same position for some reason..
Rule number 1 is to never hang powered speakers, unless you can easily reach them and monitor them.. Also never turn the knobs up to the max, like most sound guys would do.. Newer speakers should be leveled after you eq you mixer and sound sources..
I’ve had my pair since they were 1st introduced in 2017.. Only issue I had was with the extension cord power source not sitting snugged within the sockets.. That also includes the use of the locking power cable provided by the manufacturer.. The power must be snugged..
Same here. I have issues with two of my K12s, one of my KW152s and one of my KS118s. Never had an issue prior to Covid but it seems like I’ve keep running into issues with the gear that I’ve bought since then.
This might be why QSC’s wood cabinet KW line still uses the original amp from the original K series… the KW122s sound better than the plastic cabinets but it is a little bigger and heavier.
Their PLD amp line (now discontinued) had some issues so I’m in the process of selling those off for my mains. They have been great for monitors though.
Also have KS118, K12, K10.2, and the KW122s I mentioned. Never had a problem with any of those, but I do agree that since Covid hit, their company is a little bit more hit or miss than before. The PLD amp line came out around 2013 though and wasn’t their best and what I’m used to. The PL380 amplifier is bulletproof though, but has no built in DSP.
I feel like their R&D is more focused on active powered speakers and Qsys networking tech these days more than amplifiers despite being an amplifier company first and foremost.
Purchased both speakers QSC K12.2 and ALTO TS312 on 02/14/2022
Played 20 gigs, with the QSC K12.2 on the right side and the Alto ts312 on the left side of the front-end PA system, and on 09/30/2023 the 20th gig, the QSC failed to work, it would power up, but would not process the signal from the PA board. Trying to get it fixed now by warranty....
I've owned a pair of K12.2s for almost a year now and use them with my band probably about 3-4 times a month. Sometimes I experience sound cutting out or dropouts but that was due to my faulty Presonus Studiolive 32R that I had serviced and now works like a charm. I do feel like there are certainly more reliability issues with this model compared to the K series of old. Knocking on wood, because when they work, they are brilliant sounding speakers.
I agree, the original K series was rock solid and these sound even better in my opinion. Too bad they don't seem to be as reliable as the K-series.
Wow! I’m shocked by this. I’ve been rockin my DOT 2s for about four years and haven’t had one issue. Still crankin them til this day!
I’ve had the same experience with my K12.2 speakers, one of them shutting down in the middle of a performance at least in three different occasions. When this happened I asked one of my band mates closer to the speaker to turn it off and do a reset. Feel very uncomfortable when using them. Both speakers have the latest firmware version.
I got a pair each of the original K8 and KW12s, still going strong after 8 years!
I own a pair of Electro Voice ELX 200 12P with the matching 18 Inch Sub and man does this sound system blow me away with how great this sounds. I've owned my ELX 200 12P's for roughly 6 months now and recently bought my subwoofer less than a month ago and they have been great to me so far!! I like my music loud and I push them to the limits and when I'm DJing I would often times check and see if the speakers are getting hot and they perform just like you expect them to!! Please be aware that I've owned speakers from JBL Eon, Mackie, Carvin, and subwoofers strictly from Cerwin Vega and the EV's have the been the best sounding system I've ever owned.
Yeah that’s Factz the EV 200 series speakers do sound damn good they get loud and be clean been thinking about getting a set myself!
I have 2 12.2's and k118 sub. I use them for band gigs. I feel like these are more for that. DJ's go especially hard. Those 3 speakers are absolute bangers at shows. It is unreal how loud a band can get with them. They all stay at 0db, sometimes outdoors I will pump the sub 10-15 percent over. All this being said, I am about 8 months into my purchase and you're scaring me bro lol. I have been looking into buying a pair of the 8.2's for monitors. I can say that I am close enough to sweetwater to drive and pick up purchases like this. It never sits right to have such expensive gear delivered to me. delivery people are so overwhelmed I just don't trust them to handle with care anymore.
It's not just you, and not just bad luck. I had the exact same experience with a K8.2 that I was using as a floor monitor. Got some feedback during a performance, muted it within 2 seconds but the amp was fried. It was only 8 months old so still under warranty. Took it to an authorized shop. It took 8 months to get a replacement amplifier. Like you, my confidence was shaken in what I'd always considered a premium brand. Unlike you, I cannot afford to replace all of my QSC speakers so I'm kinda stuck with them. But you better believe I'm really careful about feedback now. Who knew that you could kill a speaker due to a software problem?
Had my K12.2 in 2020 or 2021 and a little less than a year it just cut off during a NYE gig. No power, won’t turn on at all. So yeah I’m scared to get another. Sticking with my EVs however I’m itching to get the KS118 Sub
Love my first generation Pioneer XPRS 10” mains, Baltic birch-55-20k hz-134spl-Powersoft amp 90x60 degree angle. Only drawback is there are 41lbs for a 10” speaker which is slightly heavier than I want. Considering replacing the LF driver with a neodymium to lighten up the weight
Got a K.2 10 for a monitor and has shut off on me twice at gigs. Been back and forward selling it, but this video sealed it for me. I just ordered the Everse 8 to use for gigs.
Did you try updating the firmware? Did you look to see which version of firmware your speaker was running when it failed?
Thank you so much for the vid. I had the same issue with my k12.2. I was djing a high school event and wasn't pushing them hard at all and they shut down. Luckily they went back on after resetting them. I thought it was a fluke but it did it again at another event but this time it shut down completely. Sent it back to QSC and they sent me a replacement. I can't trust K12.2's any longer so I sold them. I miss my legacy k12's. I switched over to RCF's and love them!
Yeah RCF has some good stuff. My original k12s, KW18s, etc are all going strong. I made the switch to BassBoss and am so happy
@@hamster1717 Great stuff. Bass Boss hits hard!
Same exact thing happened to me! Sent them back went with rcf and haven’t looked back since
@@MrMaui38 It's scary to think that this would happen to such a reputable speaker. I was very disappointed. RCF's are the way to go. They're simple and sound great!
@@jasong.3985 Exactly! I was so surprised and disappointed after how many QSC products I’ve seen used by other DJs, and how many good things I’ve heard. When I called QSC service center back then, they said that they were expecting a recall for the new amp modules that had started going out post Covid.
Very surprised by these stories. I've installed 3 sets of dot 2s in the 3 venues, and never had problem with any of them. I also own 2 pairs that have been hammered since they came out, and never an issue.
I had a brand new K12.2 die on me last summer, only 1 year old and used for maybe 15 events. The amp module was bad, they released a few bad batches I guess. I got it fixed under warranty, pretty bummed though. I''ll probably keep that one and sell my other 2x other road dog k12.2's.
I run two show locations that use 6 k12.2 each (12 in total) 4-5 shows a week. Over the past 2 years we’ve had to send 5 amps to get repaired/ replaced. Mind you we don’t run super hot signals through these speakers(never in the red) I also know others that send almost 1 k12.2 a year to go get replaced/ repaired. Build Quality is definitely not the MOST reliable but they sound so damn good. I do think most of the damage was caused by rain and sea breeze though, only other incident I’ve had with a k.2 series is when they are in hot weather they go into protect mode. Definitely invest in a solid way to protect these speakers from the elements.
I have been living with Protect Mode 4 on two K10.2s that I bought in 2021. Due to Covid, I didn't use them much until this year. I've now had 4 outages with one speaker and 5 with the other. I use these as either light duty mains or as monitors. Firmware is updated to the newest version 1.3.3. I sent the speakers back to Thomann for waranty service - all they did was update the firmware and send them back.
I've got a case open with QSC, and I have seen a service bulletin that indicates that a hardware fix needs to be made. I'm hopeful that QSC can make this right, because right now I can't trust these speakers. My old K12s were absolute tanks, but these things are currently too delicate. My hope is that QSC can swap out the amps and I'll be good to go, but for now I'm far too scared to take these to a gig.
One has to perform the firmware updates when available from QSC. I think the firmware updates addressed the overheating issues.
Thank you for making this!!! I bought two brand new 12.2 last year whos amps shut down middle of my gig last year…twice! I returned them immediately and went with rcf. Extremely disappointing and I’m glad to know I’m not the only one with issues!
Dang sorry to hear that…that’s super frustrating. RCF makes some great products 👍
did you update the firmware?
@@devere9675 I didn’t try that before returning them so can’t say if that would have fixed it. I did call QSC service center who did not mention that either. They were brand new out of the box so I would assume they had the latest firmware.
I was about to pull the trigger for QSC K8.2. or K10.2... now not so sure! What RCF model did you buy ? 712 MK4 ? 732 ? 912? 932 ? something else?
@@francoisblanc6453 I bought the RCF HDM45 which are bigger so may not be a good choice for you if you’re looking at the 8.2 or 10.2. I had the issue with the 12.2, so I wonder if the 8.2 or 10.2 would be okay?
The RCF HD10 or 910 is a good option if you’re looking at 10 inch speakers but I’m not sure of any comparable 8 inch options to the 8.2
I have QSC k12.2 speakers and facing an issue of output
And all the sig light are turned on to green
bom vídeo...eu tenho um par dessas caixas k10.2 e uma delas ja entrou em proteção ...acredito que foi queda de energia ...depois do reparo na autorizada veio atualizada o firmeware ,atualizei a outra caixa também...uso elas constantemente volume no máximo em 0 ou 1+ db as vezes com Sub k212c ...nunca usei estabilizador de voltagem (((recomendam)))Mas confesso que também perdi a confiabilidade!!!e o modelo K" antigo não tinha esse problema!!
Which speaker do you recommend between QSC K12.2 k.2 series 12” and electro voice FRI 2082-BLK Dual 8” two way.
Bought 3 pairs of K12.2's and 3 pairs KS118's 6 years ago. Still going strong.
Well I got both legacy and the k.2s no problems this far but that’s for the info I did the firmware update. I’m not sure what it did but K.2s still work🤞🏾
I purchased the KS118 as soon as they dropped in 2020...both woofer blew on gig #2...The official QSC dealer said my serial numbers fell just outside the range of serial numbers they were looking for.....after that I felt kind of uneasy about them so I sold them and started back using my KW181...which I can turn up louder with no issues ...Unlike the KS118's the limit light started coming shortly after turning on the speakers and especially if you turn the gain to the 1 oclock position on the amp. I have the original K12's and KW181's I bought since 2017...no issue ever.
That’s the crazy thing, the original K-series (KW181, k12, etc) were so reliable and so good that it’s surprising the new ones have as many problems as they do. I bought a pair of original k12s :)
@@hamster1717 Which is better for DJ. the QSC KW181 or the Electro Voice EKX 18SP
I’ve been considering the K10.2 bit this is worrying to hear.
I notice on QSC’s website that all the .2 range had a new chipset revision from 5th Sept 2022. There has also been subsequent firmware updates for this new chipset and I’m wondering if any of the recent issues had these new chipsets running the firmware 1.5.5 version?
I’m also considering the EV ELX200-10p as I’ve read a number of reviews say they prefer them to the QSC’s though I had reliability issues with the original ELX Line-X range.
I remember when the k.2 series came out. I was all set to upgrade from the legacy series I own but just never heard much of a sonic upgrade. If anything, the new K.2 series didn’t sound as full and had more background hiss. I have stuck with my original K12s which sound fantastic.
I bought 2 K8.2s. Love the sound. Never push them hard. The (all my gear) looks new. 3 years+ in - one stopped dead @ a gig -no sound. Luckily I have 3 yrs left on the ext. warranty. I did update the firmware. Just shocked. think I'll go back to using my crown amp with a pre and power 2 QSC E110s. Amp module suspect. QSC factory did apologize via email and will fix it but...possible 2-3 months wait. Hmmm.
Which is better for DJ. the QSC KW181 or the Electro Voice EKX 18SP
Thanks for the vid, Very true my k12.2 2 out of my 5 are giving me issues, nothing like the original K12s can take more of a beating
Issues galore with the K10.2s
K12.2s have been absolutely flawless, as have the KS212c subs.
I'm not a DJ though. Sound guy, this is my mobile small gig rig.
hello, can you tell me if the Electro Voice EKX 15p is better than the qsc k12.2 which you recommend. it is for DJ use
I just bought a pair of QSC K10.2. My current dealer has confirmed to me that with the new firmware 1.5.5 the problem has been corrected. Well I hope so - what do you think?
What many people don't realize with self-powered speakers = a speaker (especially a subwoofer) is a VERY harsh environment for an amplifier/electronics to live in. Think about the pounding, rattling, shaking, vibration that the amp is subjected to while in use. I am not saying this was the cause of your failures, but I've been in the business 35+ years and by comparison, I have never had a power amp (rack mount 19") ever fail - across thousands of uses and installs. IME passive speakers powered by external amps are far more reliable. The world's greatest speaker systems are passive and powered by external amps (d&b, L'Acoustics, Adamson, Danley, JBL VTX etc.). I have tons of powered speakers, don't get me wrong - but seriously considering going back to all passive for the above noted reason, plus not having to run power all over a stage and venue. Side Note: I installed (6) KLA's in an auditorium (2015 I believe) and (2) amps died within 3 months. Manufacturers need to get back to a focus on reliability. If a speaker doesn't work, it doesn't matter how good it sounds.
and the heat too.
this does not make sense as original K series did not had the issue which had all the things. Most likely this is quality control issue with parts in amp or design issue.
I have a K12.2 that failed at a gig for no reason. It just cut out and all the input lights stayed on even though no source was plugged in. Took it in to an authorized QSC repair shop and they said something on the amp failed and that it was an ongoing issue with the .2 Series speakers. I paid almost $400 for the repair. I’ve only had the speaker for about 5 years so I thought it was still under the 6 year warranty. The problem is I never registered none of my QSC speakers that I have so basically it voided out the 6 year warranty and made it a 3 year warranty instead. That’s my fault for not registering the speakers within 30 days of purchasing them.
Same thing happened to me 😮 It happened to me several times at some important events. I was totally embarrassed. I ended up selling 4 of them because I couldn’t trust them. I had the original k12 for over 8 years with no issues
The original k12s held up so well (I recently bought another pair) it’s sad that people are having bad experiences with their new products.
No problems ever with the QSC K12.2. Great sound and performance ...
I do think the problems are rare but they are there. The k12.2s have a good balance of sound, SPL, weight, and price though
The k.2 series has a flaw in the design for the amp and has a recall but they are only replacing the amps as they go out. I run a pair of k 8.2's and have had both amps replaced and have had no issues since. These were installed in 2018 and both amps replaced by end of 2019 no questions asked.
I thought I was the only one who felt this way! I've had reliability issues with my K10.2 speakers and my KS118. The amps fry so easily and a woofer blew out on the KS118. I have 4 amps sitting in my house that I have replaced. I do not recommend these speakers anymore for this reason.
You need to make a video about this. I just seen your video recommending them. Now I see you changing your mind.
@@gatchmanphoenix1418 Yeah. I did recommend them after I first got them. That was what... 2 years or so ago? My opinion has changed now. QSC really lacks in the reliability area. That's been my experience.
I still have the jbl eon 615 with my dbx drive rack and my avante imperieo sub 215 and they rock
question - do you think the k.2 issues are the type that, if they're gonna happen, they happen right away? e.g. if I buy used ones with multiple years of reliable performance, would you expect that they're past the window of potential issues?
any news on this?
Teufel POWER HIFI stereo or QSC K.2?
Burned over 6 of my k12.2, so I sold all 8 & bought 4 KLAs. Kept all my KW & K series subs & tops. The analog boards don't have to worry about the DSP chip malfunction.
The new series use a 2ohm ceramic speaker instead of 8ohm, cheap dsp chips and warranty is useless if they can't keep up the supply of parts!! Hopefully the new L array series doesn't disappoint but then again.. its digital as well..
Do you think an Everse 12 would sound significantly worse than a k.12.2? ... I want a speaker with a battery and I'm torn between buying an everse 8 for around town or selling my k.12.2 to buy everse 12... around town would be acoustic guitar and vocals, but my use case for k.12 at home is a power amp for my electric guitar modelers and simultaneously playing practice tracks... would I miss the QSC at home if I went with one everse 12 speaker for everything?
I have these and it works flawlessly going on for over 3 years.
Which speakers do you recommend? , I have qsc k12.2 and same thing happened to me , so want to change to different company , thank you for your help
The original/"legacy" K series from QSC is still great. I now use (and recommend) BassBoss DiaMon 112s and RCF TT10A's. Both are under 30lbs and get stupid loud. The DiaMon is a coaxial speaker so that has some benefits, while the RCFTT10A gets incredibly loud and can network with the rest of the RCF life. I am lazy so I like the lighter weight.
My "bigger" mains are Fulcrum FA22ac's which are the best sounding speakers I've ever heard period. They weigh 60lbs though so they can be a pain in the ass to get on stands. They're also discontinued :(
Totally agree sir people are having trouble with these, i have 10 of them after selling my original ones constant firmware updates and fragile !
Which is better, QSC k.2 series or L class series?
Well what the peak spl level when ppl are having issues? Or are the using a powered mixer /DJ mixer on already powered speakers? Not sure why feedback would shut it down but maybe it’s a safeguard when ppl aren’t doing things right type thing... not sure. Two yrs into mine but I don’t need to go super loud.
That was the weird thing. I’m so paranoid I make sure there are no limit lights on or anything. The feedback wasn’t super loud; I’m just surprised it fried the whole amp (if it was too much power drawn, it should have just blown the fuse). It’s a puzzle for sure
I had 2 qsc k12.2s go off at the same time on two occasions and have had them break more times than all my 22 qsc k series speakers combined.i agree with you these are very sensitive and are bad for 220v regions even with the firmware updates.
My k 12.2 have been a nightmare. They have been in the repair shop 5 months and still cut out and have to be restarted 😢
Im a Dj but new to hosting outdoor raves. What speakers do you recomend ?
Now looking at the Mackie DRM 15" active speakers and 18" DRM subs.
What do you recomend for Techno music ?
The Mackie DRM series really impressed me. The 315's sounded great as did the subs. What size events are you trying to cover/how many people?
@@hamster1717 2-500 peoples.
Sounds like you need a line array (the kind you hang)
After 2020 QSC reliability is not the same. I have a pair of original 12.2s work great ( purchased new in early 2019) - i purchased a second pair of 12.2s in 2022 (that's when I started having problems - mostly shutting off randomly).
Yeah it’s unfortunate that their quality control seems to have gone down. They used to be one of (if not the) best
I have just been given one to repair K12.2 i think. It is under warranty but the other one also had issues and it took him one month to get it back From Thomann. He uses it on a ski mountain so the next month Feb March is important. Can't be waiting one month again!
So, they shut down after 3 seconds then reboots and shuts down again in this endless loop.
I'll be opening it up in the next few days to have a look. But 2 units still under warranty both broke! I could not work with this. Imagine i turn up for a €1000 wedding with those! Personally i'll stick with my RCF or my V15 Tannoys and use the Martin Audio for the bigger events.
I do use some QSC gear. I have some power amplifiers which have mostly been ok but the 6kw Powerlight (PL6) died unexpectedly and my first repair failed the power supply mosfets are super expensive!
I have a CX404 which is not too bad but the volume pots could be better. The PL236 seems ok but the PL4 has an earth hum on one side which i find surprising. It's not enough to notice with music on so for now i'm not bothering to open it.
I guess the older stuff was made better but doesn't last forever without expensive servicing.
I have 4 K10.2s..Two of them stay at home. two of them i bought from rental and are lugged around for PA uses.. Theyve broken down on me a couple of times. I wont get into it right now (maybe slowly over time) but i wont recommend QSC either, for multi reasons. One quick one is an 8 month wait for a small part and then only to be told its not made any longer....also: Try calling them and see how THAT works out for ya. They got my money, no need to answer the phone....i guess i own them for better or worse at this point, and unless i feel like spending another 1500-2K , ill just have to use them. Where on the presets is the best place to start for guitar reproductions? for instance as an frfr for Helix, Kemper whatever. Thanks for the vid and giving us a platform to obtain information. That alone gets you a thumb up here! EDIT: also gotta wonder which input for guitar? Looking thru the manual, it seems as if input A bypasses the preamp of the K10, and B does NOT!
Use a mixer instead of directly plugging into the speaker.
I have six k12 tops, and three k-Subs. Super reliable. I never had an issue with the legacy line either!
I bought my K12.2s in fall 2020. I bought my KS118 in summer 2021. I use them weekly at my live blues venue. Never had a problem and I've never updated them. Is this because of when I bought them? Maybe the shutdown problems started with the same speakers after the ones I purchased? I keep hearing about the quality of parts in the amps. The amp modules are blowing because of inferior parts and not the design. Perhaps the Covid epidemic had an impact on getting quality parts because of supply chain issues? QSC doesn't say or acknowledge this. That's why people are mostly pissed off. From what I know, the amp modules need to have certain parts replaced. A lot of repair techs have been saying that.
As a rental/production house we own over 20 K and K.2 first K series no problem whatsoever. One fan died on me in 10yrs. K.2 two amps died in the first 6 months. Same use same events. QSC replaced the amps with warranty quickly. I am on board with you on reliability and so on. EV speakers match and in some cases surpass the quality. JBL is always a good buy. Price is also a problem as well. They behave like Apple in some cases. Still have my K12s and they work without problems. TBH we do use EV Evlove 50 now more than the QSC on a lot of corporate events
hello, can you tell me if the Electro Voice EKX 15p is better than the qsc k12.2 which you recommend. it is for DJ use
So you admit you had problems even after claiming you didn't?
Yours isn't unique, but I was told that the firmware update ... supposingly cured the issues - I'm yet to get surprised?? I've managed to solve issues with re-initialization ... but I'm not satisfied with doing it during soundcheck.
How’s it going in your opinion what are the best loudest speakers for a wedding DJ
BassBoss and RCF makes some of the best and loudest active speakers. Also look into L’Acoustics, DnB Audiotechnik, and Fulcrum Acoustics
I’ve had bad luck with my K10.2s and K12.2s! Amp problems, argued with me at length that I didn’t fill out my warranty on time so no warranties for me. I like them but I make sure I bring at least 1 extra top in case 1 stops working. I keep my trailer humidity controlled at 50%. They’re in cushioned cases. Never pushed near max. Always have large subs with them. And have them surge protected via higher end Furmans FWIW. Aside from QSC K2 stuff I’ve only blown 2 woofers in 33Ys! If they’d even offered to sent 1 or 2 amps I’d have been happy, but nada. The amps are easy to very easy to replace….
I had a qsc k2.2 after 4 hrs of use they start clipping
The quality and reliability of all powered speakers is clearly marked on the back panel . If it says made in PRC , youve bought yourself a problem .
Bro if you like the original k - series, get a set of CP12s and let us know what you think. I own 4 CP8's, super reliable.
I love my CP8’s!
@@Ronniezim me too!.....
I’ll consider these issues but u will need to give me detailed recommendations as well
I used to work for a rental company as a technician, it’s true we did have some K.2 who burned out but it was all before the software update, now it’s working like it should for a QSC product. I’m even looking to get a pair of K10.2 myself
I almost pulled the trigger on these until 4 straight days of researching after seeing your video and for the price you pay for QSC, it's not worth the headaches. The K12s are rock solid but the 12.2 produced during and after the pandemic has an uncomfortable failure rate that no professional band or DJ want's to encounter which is very sad because I've heard these and thought they were perfect for the type of music I play at events. Now I'm down to JBL PRX912 or RCF 912A. The only thing I didn't like about the RCF 912A is they don't have the DSP, but the one thing I love about them is plug n' play. Has anyone else had better luck with K12.2 manufactured after 2023?
I had one completely fry and the other fail and then somewhat work tonight at a worship event. And they weren’t being pushed very hard at all. I am beyond sick right now…
Did you update the firmware
tnx for the update
I have the original K12 speakers and I still think that they sound better than the K.2 series. They can handle the load better. You can really push them to their limits and still sound amazing
All Factz I have two OG K12’s and I love them two death they just work and sound great!
you had a lousy experience bro I know how that feels but my Qsc is in perfect condition after 4 years of use. I do weddings for over 400-500 people with two EV exks subs and great sound.
I own 7 K10.2s. I've had two of the amp sections completely shut down. However, both speakers (out of warrantee), were quickly repaired and have been working consistently since. 2 out of 7 is not a good reliabilty percentage. However, good news, they were quickly, easily and economically repaired. The service (Triple S Electronics) was amazingly quick and sent a full analysis of the unit's performance. What other brand can be serviced like that? Stuff breaks for whatever reason. I want to know that things can be repaired, that's almost as important as how reliable they are. When I've tried to have Mackie, Yamaha or EV units repaired, I was on my own. Not so with QSC. Also... in my opinion, the K.2 series sounds A LOT better than the K series.
What was the issue you had with the amps? It sounds like the amps themselves weren’t completely broken, but rather it was something small where they didn’t need to be completely replaced
RCF 932A is 3 steps from these but you be shocked with the fbt 114a
I bought a pair of Alto TS415’s. Years ago I had TS315’s and returned them rt away because they just sounded weird. Since Alto replaced those and added more power all I can say is wow! QSC watch out because Alto is competing directly with y’all at a much more cost effective price.
I just got two of them, fingers crossed. My question is I notice some white noise even when there’s no inputs. It’s not major but not sure if it’s normal?
Yeah that’s normal, it should be pretty quiet though. With gain staging you should be able to adjust how much there is-see if when nothing is plugged in whether you still get the noise and if it changes based on the volume knobs (even with nothing plugged in)
I have a friend of mine who does sound and he cranks the knob 100%.. He must use a digital mixer at all times to cut out the ringing feedback.. Meanwhile Im using a dj mixer running 4 mics at times with no white noise or feedback.. Maybe He thinks these speaker’s operate like his old passive systems.. 🤷🏾♂️

Any updates?
Mine cut out on the first performance after buying new ones. Yuck. I would trade them in for legacy K speakers. Thoughts on preferred speakers a year??? Thanks
Dang that is so frustrating. For lightweight mains I now use (and recommend) BassBoss DiaMon 112s and RCF TT10A's. Both are under 30lbs and get stupid loud. The DiaMon is a coaxial speaker so that has some benefits, while the RCFTT10A gets incredibly loud and can network with the rest of the RCF life.
@@djmyr Today I traded in my k12.2 for legacy k12 off my experience with the older ones my boss has. Never an issue. I'm probably the only one trading in old for new & am stoked for it too! Your video definitely helped me pick a lane before more of my gigs occur! I'll give an update in the next few weeks fingers are crossed!
new for old lol🤣
@@Highvibesociety. Nice. I recently bought another pair of K12s (the original) about a year and a half ago. Zero problems and I use and rent them out them all the time. It's a good purchase
I have another QSC speaker that just went out, my KS112 Subwoofer. Took it out to a small gig I had yesterday paired with a K8.2 and it wasn’t working. I’m having the same problem that I had with my K12.2, the green signal light illuminated even though there was nothing plugged into the speaker. I bet it’s the amp that went out again. This is totally unacceptable QSC.
So what did you go to instead of QSC?
These speakers are solid!!! Highly recommend these over other brands (JBL, EV, Mackie, etc)
Looking to buy soon.
What would you recommend?
EV ETX, JBL SRX, BassBoss, or RCF would be my top pics (in no particular order). The JBL SRX stuff never let me down, the subs in particular were very impressive. The ETX stuff sounds great, and RCF and BassBoss have great reputations for a reason (BassBoss has an unbelievable warranty).
Yamaha DZR too but Ive heard some problems about the DXS18XLF.
Finally Mackie DRM really impressed me for the money. You can always buy a pair of used “legacy k” like the k12s, those speakers are amazing
10 qsc k12.2 just love them.I never have a problem with them.
What sub did you have in front of these? Not a QSC. Maybe the common denominator here is a faulty sub passing DC to your mains.
The problem with the K.2s is the DSP. I stay away from any speaker/amp with DSP and preset functions. The originals were simple and straight forward.
Have you thought about the Mackie SRM450v3 1000W 12-inch Powered Speaker or even smaller SRM 350v3, which I love as I pair them with the original QSC K12 series running my 4 tops of Mackie/QSC SRM 350v3 10-inch blows the competition away even the CP8s are on stand by with my collection of the QSC/SRM series of speakers front of the house, You are correct I do not like the K.2 series!
I believe something was wrong with your speakers or the setup you were running.
I have k12.2's since 2019 and never had an issue.
Even the issue that a lot of people were having that the speaker stopped working and needed a power cycle became of a faulty limiter security feature.
Regardless, I've done all the firmware updates for the k12.2 available online and updatable via USB cable into the speaker from a pc.
And it never had that issue
The majority of the problems are coming from speakers manufactured in 2021/2022 during the supply chain debacle. QSC started using crap components from China because they couldn't get their regular components. Now there is a trust issue with QSC. The company is very good at honoring their warranty.... but some of us are actually using these speakers to make a living and can't afford to risk losing gigs because of unreliability.
Good morning !
after 5 years of use of QSC k12.2 I have never had a problem! I pushed them to the limit multiple times for hours with no problem. these are the best speakers i have had. apart from a slight vibration of one of the k12.2 at high volume nothing abnormal. still working day after day. some feedback and nothing to explode. I am in canada therefore, with the 120volt and not 220volt sockets. I do believe it does! they seem sensitive to 220volt despite software updates. have a good day! thanks for the video !
I have 10 K12 and 10 KW 122 when they came out with those speakers I didn't like them because they have to many settings .. The old ones you just put the cord in and turn them up !!!!!! AND THEY WORK
Do you recommend the QSC ks118?
I do....I have a pair and they are awesome
Me, just having got k12.2 😂. I’ll update if they fry!
Hopefully you have better luck than I do. QSC is great about their warranty if you do have any problems
Yorkville is a damn good speaker it’s all made in-house except the speakers inside but they use Italian made b&c drivers The amp board is not made in china it made by yorkville . Qsc make great amps but the powered speakers are not as good. Piece of advice if you installing any speakers get a drive rack pa and set it up so you won’t destroy your speakers
I bought a pair of K12.2s in January 2024. Used them on 2 gigs and they sounded great. On the third gig one of them died. I checked the firmware, and it was up to date. I asked around and another band told me they had the exact same problem. The tech guy at the QSC authorized service center told me in confidence that he is constantly getting K2 speakers in with the same problem, and he explained that the ones with power modules from China have incredibly high failure rates. The wait time on replacement modules can run well over a month.
Yes, QSC will repair or replace them when they fail.... but that won't help me when I'm on a gig and they die.
If you are a working professional musician, you can't afford unreliable equipment. I'm done with QSC for now. It's a shame, they sound great.... but being unreliable is a deal breaker.
I have allll RCF sound but lucked up and snatched 4 of the legacy K12’s only because I got em all for $800 from a guy who always goes for the shiny “new” gear and sells everything. I already had a pair that I kept to rent/backup and of course now dude is on DJ forums complaining about his k.2’s and how he hates he sold his old ones (& I keep my mouth shut cause I’m not selling them back ever) 😂
Mines caught on fire during a gig
I was so bummed and embarrassed after being so happy to buy them. Now with multiple live gigs in the coming weeks; I'm at a crossroads.
