Boom!! 120 dB crew in the house!! Great video!
Thanks Channa! Appreciate your support bro
This is a great discussion!
I have done this myself many times!
My comment does not really deal with the possibility of doing this or physical constraints, (amplifiers can handle this) but rather running room EQ on subs that react differently than what the EQ software is expecting.
The room EQ software is written with the assumption that the output impedance of the amplifier (or sub-out) is matched to the sub input impedance in order to make the necessary adjustments to the gain (mostly) and to a (lesser extent) freq. response.
By doubling, or quadrupling the number of impedance loads on a single sub output, and having no way to tell the software that it is driving into a smaller impedance could lead to incorrect settings.
That's all.
And, yes, I DO know what I'm talking about. :)
40+ years in audio.
You can also use a good quality RCA "Y" adapter at the subwoofer input by either piggy backing to additional subs or feeding a left and right. I like using those instead of y-cords.
I make it with rca Y. Connect 2 active subwoofers. Awesome 🤘🤘👍👍
Running four 12" passive subwoofers of off one amplifier channel in my listening room/home theater. More the marrier I say. Thanks for your video.
I agree, now that I have two subs I'll never go back. Its amazing
Good video bud. Again very easy to follow for some who had questions on how to do this. Also, glad to see your wife supporting you on Patreon! 😂👍
Thanks! She supports me in everything I do. 👍
@@Youthman Oh I know 😉 You've got a good support group behind you my friend
Life of Bliss she’s awesome. Happily married now for 23 years
Eq video next using the SVS app and REW next please!
just like to say thanks for all the sub + REW vids in laymen s terms.i went out and purchased a mike from off your list and downloaded REW.followed your vids and now have my subs set up with tighter bass.i have the ultra pb 16 and a monitor audio gold 15" sub.both working together.its given the sound different dynamics now. ive played both blurays and hifi content , both sounding better. it makes a difference when some one whos not a rocket scientist explains the up's and down's as they are learning too, so we all learn as we go forward..
Your set up is insane my walls vibrate like crazy I can’t image how wild yours pounds thanks for the video I’ll b checking for more
Thanks Jason, that's actually a really old video. I now have a pair of JTR Captivator RS2's (see some of my recent videos)
So Youthman. This video is for the rookies! Keep up the great work!
Of course it is. I can assure you there are plenty of them out of the 35,000 that subscribe to this channel. I want to be able to provide content for the novice to the audiophile.
Another great video! More awesome useful information. You do an awesome job making tutorials. They always have useful pertinent information, and they are easy to follow along. Have great weekend man!
Thanks Hi-Fi. Hope you enjoy your weekend as well
WoW...you must be a rocket scientist to figure this stuff out....Thank you
This video is primarily for guys just getting into home theater.
A super easy way is to use the SVS wireless kit(s). Works flawlessly.
is there a quality difference between xlr and wireless kit signal ?
IPlayGames of course, xlr will be more powerful and have be more tight/ detailed
Great information 👌
a lot of people don't know that
Glad the video is helpful
The answer I can’t find is what to do with multiple subs on a Y splitter(s) (3, 4, or 5 or more) with Audyssey. Should we set their volume levels individually or set their gain together when Audyssey begins?
Great video Michael, now another video is needed, on how to tune those extra subs. Maybe with a more basic receiver, that won't recognize more than one sub.
I I have my dual sub outs split twice each....running 4 subs. I have gone as far as splitting 3 times to run 6 subs. Works perfectly with very little signal voltage loss. If you experience signal loss you can add an ART CleanBox Pro to boost the signal levels and change from RCA to XLR as well. The other option is to use a MiniDSP to boost the signal levels (along with using the DSP settings for each channel) Nice video man.
Love it.... Need more Sound demos.
Blessings to you and Yours.
Thanks. Hard part about sound demos is copyright strikes. Too many and CZcams will pull your channel.
Truly understandable.
I know a lot of the "vocal coach reviews" get away with playing less than 30 seconds at a time, then talk for 30 seconds to a min, so the YT filters, don't pop them.
I’m going to buy 2nd sub immediately, thanks youthman
Have fun!
What sub are you getting?
Youthman I’m in Saudi Arabia, not much brands are available, I have one Klipsch R-110sw, either I have to go for same model, or Polk HTS 12 which is available locally, otherwise I need to import from USA the SVS and pay fortune to get it here through custom duty.
Great explanation on how to hook up multiple suds.
On these pre/pros are you able to utilize the RCA and XLR pre-outs at the same time? Could you connect 2 subs with RCA and 2 more with XLR?
Great video...still patiently waiting for the JTR sub review...:)
That will be awhile. I shipped the JTR back to have it tested since if there is an issue, Jeff wants to get it resolved quickly so he can begin fulfilling orders.
In the meantime he is sending me a pair of R2 subs (dual 18’s) as soon as they are built. Stay tuned
Your home theater must sound amazing...
I’m running 2 subwoofers in my living room and both of them are cranked up but they are setup for good bass on my receiver so they hit hard but won’t blow
Hello
i have an existing home theater, receiver it is from yamaha rx-v496rds but i don't have sub woofer. Now I bought a JBL sound bar so I can play music via Bluetooth. I wonder if it is possible to connect these two systems together?
Thanks for the reply.
my receiver Sony STR-DN1050 has two sub outputs but only has one calibration/configuration for a single and not dual subs. Do I just run the auto calibration with both subs connected or just one connected? I'm confused because if both subs are connected (both rca out on receiver to the LFE on the subs) and I run auto calibration how will the reciever know which sub to set the distance and db for the sub?
So how to configurate In the menú? If I have two outputs how to configurate the second one
This is what I needed to no. How to hook up 4 subs ! Thank you .
hi thank you for the video
I do have one quesion I do have VSX-LX305 Elite 9.2-Channel Network AV Receiver
I want add. a Subwoofer to zone 2 I would like to put i would like to put Subwoofers work only with zone 2 any idea how can I do that
I have never found a use for Zone 2 so that is an area I’m not familiar with. My guess is the preouts are tied to the main zone so if you were wanting to listen to music say in the bedroom on Zone 2 with a sub, you could use a subwoofer that has a line level inputs. So AVR to sub with speaker wire into line level inputs on the sub, then speaker wire from the sub to your two speakers.
@@Youthman thank you for your reply 🤝
Id like to know if I can hook two receivers together to make one. Two receivers combined power .
Technically, yes, if one has pre-outs and the other has inputs for those channels. But I personally don’t recommend it.
This is where I get lost. I had 2 paradigm ultracube 12’s. Moved to a new home and starting a new set up. Upgraded to a pair of SVS PB 3000’s. Getting to run Dirac tomorrow, but though I could also wire in my ultracube 12’s in the rear of the room. Not sure how to make them all play nice together. 🤔🤔
If your AVR does not have 4 independent Subwoofer outputs, I would recommend a miniDSP 2x4HD. You will also need a calibrated mic and REW.
If I have four subs could I connect two subs to balanced and two subs to unbalanced? I have the Marantz av7703
Thanks for this info. Would it degrade the signal, or should I avoid using multiple RCA cables between the receiver and the Sub? For instance, an RCA cable from the Receivers to a wall plate I installed which then converts RCA to shielded Co-ax to another wall plate where the Sub is, then I convert it back to RCA and plug it in to the Sub. Should I avoid this and use grommets in my wall to ensure only a single RCA cable is used from end to end?
Is there any advantage to using a splitter from a single out put vs daisy chaining two subs?
No, either way is fine. The only benefit with Daisy chaining is sometimes it can be a shorter run. But there’s no difference in sound.
Damn!! Did this man stack his Klipsch Subs behind his screen to create 2 Super Subs at one time?
Yes I did. Stacking gives you 6dB gain per stack so I had 12dB gain by doing so.
Youthman never thought of that! Thanks for the reply. Is ok to add multiple y splinters on the back of the receiver without degrading the audio quality?
Absolutely. You don’t want to have thirty but if you had a Y splitter for both sub outs on your receiver to connect 4 subs that’s totally fine
Youthman ok great! I tried to daisy chain two Klipsch R-120sw for the front but it looks like one woofer hits harder than the other that’s why I wanted to add another splitter. I also have a sub in the back row. Thanks for the help 🙏
Nice.
Thanks for making it simple.
God Bless
Glad you enjoyed it
Wire is good but what about setting up receiver?
Question YouthMan..Can you put 2 splitters in each output to make 4 subs??
Absolutely. You can use a Y-adapter for each of the two sub outs on your receiver to connect 4 subwoofers.
@@Youthman sweet thanks man
are the subs the only thing that should or would have the "LFE" input? do any amplifiers have the LFE out?
No there is no reason to connect the LFE to a separate amplifier unless that amplifier is connected to a passive subwoofer that does not have an internal amplifier. The only other unit you would connect an external amplifier to would be tactile transducers (ie Buttkickers, Crowsons etc.)
"Boss-man ..that was one of the best vid's on subs in ages ..great tech info! ..also a good tip for just running audio listening only (vinyl etc) through A.V.all I use the dts-neo-X music settings on amp ..subs included too! ..sound is enveloping 💜totally🎼🎵🎻🥁🎺🎹🎸🎷🎤🎙🎧🔊📯
d 🤕
Thank you
Only half way through your vid so far, but...
Please remember that paralleling two subs from one output halves the input impedance of the two subs.
This can have dramatic effects on the response and performance of both subs.
Finishing the vid...
Paralleling four subs would be even worse.
Typically, each sub input is ~50K ohms - to operate correctly (and match the O/P impedance of the amplifier)
Two sums in parallel would half that to 25K ohms, and those in parallel with two more would be only 12.5k load on a 50K output - a bad mismatch.
No?
Hi Gary, this is the first I have ever heard of that scenario. I would need to do more research. I have never heard someone suggest using a Y is a negative thing.
Will research and report back
@@Youthman Excellent! - I am not an engineer, but engineers I work with are quite concerned about matching input and output impedance between one device (circuit) and the next.
A lot of speaker and amp spec. sheets will list the devices input or output impedance for a particular input or output.
Look over your component spec sheets and know that resistances in parallel divide (and resistances in series - a rarity in audio), add.
This is not a problem at all in a normal setup. Stop woring about things you dont understand.
This was my first thought, I come from car audio and impedance is very important. Take an ohm meter and double check your impedance level in all scenarios
I have asked this question a number of times of reviewers and have not received an answer from anyone so could you help me? Preamp with single RCA sub out. Split the signal going to a HSU sub and another to a SVS.
If I set the preamp volume at say 9 o'clock and adjust for a great frequency response everything is fine. When I turn the preamp to the 3 o'clock position will the two subs and the main speakers still have the same frequency response or balance between all three?
As the preamp voltage increases, will all the amps and speakers respond the same way or do different amps have have a different ratio between input voltage and acoustical output? If so it may mean that for every volume setting the sub output level(s) have to changed to achieve the correct balance. Please help as I am considering a two sub setup but really need to know this first.
I like you as your easy to listen to 👍🏽
Thank you.
I'd like to advise is possible also.use a minidsp 2x4. Got.out from your receiver with one cable and than ho.throw two or four subwoofer. Than you can handle indipendent level, ritards and eq. Excuse me for my bad English. By .. from Italy
Yes you are correct. I have one, I just need to learn how to use it
@@Youthman i have my two 18" subs wired using minidsp. I had used rew simulator to find best position. Than measured and rew calculated eq for each.sub, than i.copied the parametric filters to minidsp... the result is very good response
what if you use speaker wire
The only reason to use speaker wire is if you have a really old subwoofer that does not have RCA inputs
Youthman
I have some passive subs im trying to get working
Would you prefer 1x15" sub or 2x 12" subs? Thank you!
For movies, my vote is single 15, the. Get a second 15 as funds become available.
Once I upgraded to 15”, I have never gone back to anything smaller.
avc-x3800h has 4 sub outs. Can't I just plug in two subs without these complicated cable connections? Edit: Okay, when I read the readme it says you just plug in 4 subs and need to activate them in settings.
Youthman your AWESOME 😎
Thanks
As always... solid video... is splitting the signal on one out and connecting to both Inputs on the SVS increases the signal strength?
No it would not increase line level
Youthman i want to go big, sorry - BIG in my movie room with subs. What will give me more presure and output, s3611x2 or pb16 x2 ? Room is 17 x 13 x 8.
Great video
Thank you
I have the psb subsonic2 sub with a B&W aws 1000 and the Denon avr x4400h receiver and it’s awsome but thinking on adding a 10 inch Cerwin-Vega down firing sub mixed reviews on the 3 sub system I’m just learning about equalizers I have it set up for 9.2 but I have 13 speakers I don’t know how to set up 11.3
How to connect multiple subwoofers - czcams.com/video/4A87H0DqKZE/video.html
I would recommend getting a miniDSP as it will be difficult to time align them and EQ them without it.
It was a Game Changer for my setup - czcams.com/video/_ZxbM_s4vh0/video.html
Although this video was one of the best, if not THE best, at showing the How to for multi-sub connections... one simply cannot make multi-sub connections without also taking into account where each Sub will be placed -and- how their given AVR / Preamp Processor handles each of the Sub 1 and Sub 2 outputs. In other words, one must address Volume, Distance and Phase for each Sub connected / placed in their HomeTheater. And the above has nothing to do with Subwoofer EQ'ng, or Room correction, or REW, etc. For even if one chooses to not do Subwoofer EQ'ng / Room correction, one still must get Volume, Distance, Phase and Placement of their subwoofers correct. How they're 'connected' is most often dictated by all of the above considerations, and not the other way around. Yes, another video for sure..., however I wanted to throw this out there just in case some folks take away - "all that there is to it" is a couple of connections and I'm done. Sorry, but far from it if you want it done right and sounding good / correct.
hehehe...got confused in the middle...will come back after i get the 8500H. Need to connect 4 subwoofers
Hey youthman i need your help. I having some trouble with booming bass. I have 2 subs in the front, only place i can put them, crossover its at 120hz phase 0. One sub its a REL HT1205 and the other its a Dynamo 1000 down firing configuration. And its in a corner.
Only way to know what is going on in your room is using REW and a calibrated mic to see what’s going on. Then you can use a miniDSP 2x4HD to fix some of the issues and get a flatter frequency response
Youthman The funny thing is that with music it sounds good, and i have only play the movie infinity war and that’s when i notice the booming bass. As of today the mic its still not available. So any help would be great in the meantime.
This video inspired me to search for a matching subwoofer! 😉 🔊
You won’t regret it. Check out this video on Dual Subwoofers czcams.com/video/eXfH9WH8Yw8/video.html
When are we gonna see your JTR sub conclusion video? Why didn't it perform well compared to the SVS and Monoprice subs?
The sub was shipped back to JTR for additional testing so it might be awhile before I am able to get it back in for review.
great video.....
Thank you
@@Youthman can you please do a review video oh keff Q950 or what is your openion about Q950? am very confused between klipsch RP8000F and KEF Q950. Can you please help me to finalize my front tower?
Thanks man
I needed that info.
Does the XLR connections really necessary or worth it?
I have not done any A/B comparison but in all of the research I have done, it’s mainly for long runs and to prevent or reduce interference / hum.
If you do not get a hum in your sub, I don’t see much benefit of switching to XLR
@@Youthman thanks much
amazing tip Youthman. thank u.
i am currently using Denon 2113 receiver which is 7.1 ch.
my sub is Yamaha nw sw100 which has 5 ohms impedance.
shall I buy one polk psw10 and connect it using the Y splitter?
i know you have told we can but I hav a doubt about the impedance ... your help is much appreciated ... thank you 😊
My advice would be to upgrade the Yamaha and go with something besides the Polk. Even if you buy used, you can get a lot of bang for your buck
Youthman thank u so much bro.
currently I have only one Yamaha sub.
i am planning to buy polk psw10 after watching your video :)
after few months I will replace Yamaha with the same Polk ... is that ok ??
Thanks always great vids i have the svs 2000 pro do i just go into the lfe on the back only and out the lfe on amp set to 80 ?
Hey Tom I just reread your comment. I prefer to set my crossover in my AVR or processor and disable the crossover on the axle ant plate of the subwoofer itself.
Typically if you use the LFE connection on the subwoofer, you are bypassing the internal crossover
Youthman ok so now that i am going in the lfe terminal and also have the low pass filter off means i am definitely not using the sub to crossover ?
Correct
Youthman what sub do you use
Youthman, are going to conduct a demo on the PC series subs by SVS? I would to get your take on the coverage area it produces....
Hi Michael, I have not had any plans to review the PC series. I’m working towards getting some new brands in for review since I have a ton of videos on Klipsch and SVS just to diversify a bit.
Check out Life of Bliss channel. He has a PC in for review
@@Youthman Got it... Thank you...
When running 2 subwoofers how do you get true left right sounds with them? Or is it not possible?
Most of the time you won’t because the dual sub outs on most receivers or preamps are the same content.
@@Youthman I have this sony 1100 watt amp and I'm running 4 towers, 2 shelf speakers, 2 12inch subwoofers. I'm going to go with the 6.1 setup where would the best spots be for my tower speakers? Should all 4 be center and front or should I have 2 on the very back of the room and 2 in the very front?

Thanks Youthman, another good video where my heart is.. the subs. SVS uses directional cables. Is this snake oil? You have one arrow going away from source, and in plugging your sub up the arrow goes away from the sub. Usually this means one end is grounded, the other is not. Which way is the arrow supposed to point on these cables?
I am not certain but I made a video awhile back and mentioned the directional arrow on the SVS cables and many said it wasn’t necessary. My thought is it takes no extra effort to connect them according to the arrows so why not.
I just wouldn’t pay extra for “directional cables”
I connect them in the direction of the flow of the signal (AVR to Sub)
@@Youthman Called SVS spoke with Scott. You are correct.
The arrow goes from the source of the sound away. So the arrow will point TO the sub.. but in the case of a CD player, it would point to the receiver. I asked if it really mattered, he stated only if your getting feedback would he really worry about it.
If you don't have ground hum don't worry about it, if you do the problem is in the AC side, NOT the signal cable. Lifting one end will solve the problem, but like I said, that's NOT the cause..
poserwannabe exactly. I don’t think it will matter as well
Hey Youthman would you get a voltage drop using 4 subs from 1 preout compared to 1 sub, so would you have to increase the gain on the subs? Thanks
Ha I just thought about it, would be best to re calibrate the subs after doing so?
If it does, your room calibration software will adjust accordingly
How many channels are you going to test on the emotiva?
I have all 11 channels connected in my 7.2.4 Dolby Atmos setup
Hello Youthman , do you have bass when you listen to stereo music from your Marantz AV7705? Please let me know?
Yes, I prefer using subs for home theater and music in my theater room.
In my 2ch living room setup, I do not have a sub as the wife requested no sub in the living room. This is fine because the Klipsch RF7 III have (4) 10” woofers and provide plenty of slam without a sub.
Good morning Youthman! How many subwoofers do you have in your home theatre and how are connected?
SuperBong2010 I currently have Dual SVS PB16’s. My Marantz AV7705 has dual sub outs so I use a single gable going to each sub from those sub outs.
yo love the channel and the content, but you always go big. Need some small speaker or soundbar atmos setups
Hi Franklin, when my son was 12 years old, before he jumped off a 40’ cliff, I was explaining how he could make the jump safely and while I was in mid sentence, Jacob looked at me and said, “Dad...go BIG...or go home!” And with that he jumped.
My channel focuses on mid-tier products. Trust me, there are WAY BIGGER products than what I review. $90,000 speakers, $6000 subwoofers, $12,000 processors.
The reality is I will never be able to review all of the products in the mid-tier category, much less the entry level products.
I don’t see myself reviewing a sound bar though.
Thanks for watching!
Youthman I have a xxl system just don’t want all this gear for my living room setup
Youthman pulled trigger on 5 svs ultra bookshelves in gloss white, will add elevations and sub later
Cool deal congrats!
Youthman looking for xpa-5 now
Its a awesome video dont get me wrong. But when u do these type of videos we what to hear it to. It after all a home theather channel. And what a home theather without sound :)?
I know CZcams destroys the sound but se still put om the headphones and listen.
I have audio demos on the channel but I personally don’t see much benefit other than maybe entertainment value. There is no way to accurately share with you what I am experiencing in my room.
Well by right, yes it is a signal, but due to splitting, the current in the sub cable might drop and therefore increase the volume from the receiver, but since it is 1 out to 2 subs, in fact, it would be very loud at certain positions and would increase. So according to you, they may cancel out for normal/expected performance.(Depending on room setup)
I am not following your logic
@@Youthman you do not have to, it ia meant to confuse you
So what if you have 2 sub pre outs
And want to run 4 subwoofers
I actually explained that scenario in the video 😀
That’s exactly what I had when I was running 4 Klipsch RSW-15’s
@@Youthman i only have the 2 outs on my Yamaha RX-Z9
did 2 y cables from amp then 12 foot rcas to each plate amp
i have nuance spatial baby mk2
Hey what about 4 subs on 2 sub outputs
Best method is to use a miniDSP 2x4 HD so you can independently time align and EQ them. Some new AVR’s have 4 independent sub outs.
You could use a Y splitter on one sub out for your front subs and a second Y splitter for the rear subs.
@@Youthman oh, yeah I thought it worked like that so all I have to do is put 2 Y's in the amp then run 4 separate RCA's to the 4 subs?
@nathankettlwewll3859 correct. The only issue may run into this time alignment because the AVR sees and will EQ two of the subwoofers as a single subwoofer.
@@Youthman ahhh I see
👍
What if your receiver only has 1 input ?
1 input? Do you mean output? If so, just use an RCA Y splitter
@@Youthman It has 1 L and 1 R which the R is being used by my phone with a male to two females. I tried to use the L to hook it up to the sub with the LFE one but didnt work the only thing that seemed to work was when I used the speaker output on the amp and hooked it up to the sub using the subs speaker outputs but I played very very low almost not noticable. If you could help me out it would be greatly appreciated

you don't want to be using a splitter that thin (it's not even RCA ) , i presume it's all you had to demonstrate a splitter.
I have lots of cables and interconnects including various splitters of different brand and gauge. Just grabbed one from the drawer for the video.
Also before people start poo-pooing Y-cables for hurting output, you'll only see the equivalent of a 3db change which is just barely perceptible by the human ear. Doesn't matter if you're using balanced or unbalanced cables. Math is math and crack is whack.
And that can easily be corrected by adjusting trim levels in the AVR. Thx!
3db is 50% more volume. By this rationale the SB13 ultra is not louder than an SB16 ultra? They are less than 3db different averaged across the board. It makes a huge difference.

3db is not 50% more volume, 3db is defined as the minimum change in volume that the average ear can perceive... That said, 10db is perceived as "a major volume increase"
Youthman is correct in saying that while there is a 3db drop after the split, it can EASILY be compensated no for...
@@poserwanabe really? There is less than 3db difference between almost all SVS subs. You can't tell a difference? Adding a second sub adds 6db and it is a huge difference. In subs it makes a big difference, 3db is very noticeable.

Don't make any assumptions about what I can and can't hear, I've made a good living with my ears..I was simply giving you a generally accepted definition...peace
Monolith monoprice THX 🙏👍👍👌💪......SVS not Thx 🤢🤮👎👎👎💨💩
Just an FYI, there are plenty of products that would meet THX standards but chose not to pay for the licensing fee to have the THX logo on their product.
What immature Moron
