4 ohm Speakers on Cheap Receivers: Recipe for Disaster?
Vložit

- 4-ohm loads and cheap receivers. Recipe for disaster? What about the beloved Sony STRDH190 stereo receiver? In this video, we discuss what can happen if you connect 4 ohm speakers to cheap receivers. Budget receivers often have smaller power supplies, output devices and heat sink area than more robust designs. This is why they NEVER give you power ratings into 4 ohm loads. Low impedance loads require more current draw which many inexpensive receivers simply can't provide when driven hard. We discuss two possible scenarios that can occur when using 4 ohm speakers on these receivers. The stereo receiver featured in this video is certainly an uncommonly good value but caution must be used when picking speakers for it to avoid these scenarios.

Thanks, Gene, you covered everything well. The combination of skimpy power supplies, insufficient heat sinks, current limiting, and not enough output devices to handle the current demands of a 4 ohm speaker, most cheap receivers are compromised. This is one of your best.
I remember you saying cover up the impedance switch on the back side of the receiver / amp with some tape. For they are practically useless. There was a built guy (maybe your VP) in the channel then. Many years passed, Im still watching the channel. Good work.
This is why I watch you really know you're stuff thanks so much for bringing it to my attention you're the only one talking about this problem I was about to make this mistake cause I watched some other you tube videos and was misguided so when I saw the title of your video it immediately caught my attention I can't thank you enough
Thank you, Gene! Wonderful video and explanation! As usual. God bless!!!
I still have the HK 3490 driving pair of jbl 530 in my bed room. I had the amp based on your great review back in the days. Amazing amp. Thanks Gene ;)
That is a killer amp. You did good!
always love your videos cause I learn a lot from them and use them to get my audioholic on lol,
Just focus on enjoying the audio or video instead of getting your audioholic on, its not worth it, my opinion.
Best solution imo is to have a receiver with pre-amp outs and use decent 4-ohm capable amps to drive the channels. Receivers always have sub-standard amps compared to dedicated amps.
When Gene starts to talk you better listen because you will learn something new and useful. Been a subscriber of this channel for like 7 years now. Thanks for bringing useful info to the audioholic world Gene!
Great info. Love this channel.
Always a like for audioholics! And BTW, wrath of khan has an amazing soundtrack. James Horner rip, was a genius.
I haven't done an extensive amount of research but Elac is the only manufacturer that I have noticed that complies with the 80% rule for rating their speakers. Kudos to them for being honest
Awesome job, diving into the world of AVRS's and need your guidance in choosing my starter AVR-I have three options -1. Denon 2700H 2.Yamaha RX-V6A 3. Yamaha-RX-V685
Sorry my dude, it's me again :) omg, It seems I only find your channel like once a year when I have to talk cables to someone ;) OK, now I subbed. Here is the issue and I don't wanna make you "work", but maybe you think it is an interesting subject to clear up the alchemy surrounding it some time: So this related to bi-amping. I am a more-components-is-better fetishist and so I am still going for dual mono amps etc and actually looking to bi-amp with 4 monos.
Now, I had already gotten all the specs sheets for my stuff as far as available and also bothered the manufacturers, trying to get some more info, but they are all coming back with philosophical, not practical BS. I had also asked the PS Audio "ask Paul"-service, but they could not / did not get specific in their advice. But what I gathered is that I have to gain-match amps if I want to use a fat monos for the base and maybe tube amp monos for the tweeters. - But at least via spec sheets, there is no way to do this.
Now I have seen one guy, who apparently set up a mic and measured the output in his room and he seemed to have some kind of device that can adjust/split the signal for the chosen amp pairs. - So what was he doing/am I supposed to do to get this to work? Also, what kind of kit am I looking for? Are such devices automatically studio-grade? Obviously, I do not want to go through all the effort only to mess up my signal on the last step with a sub-par gain/splitter-thinggy from China... I can see how this is not the most popular subject, but maybe you feel like geeking out on it some day, or point me to a good resource. I have 4-way (or 3.5 way) speakers with 2 sets of binding posts, as most speakers have anyway, but I could not even get out of the manufacturer how the 4 ways are related to the 2 pairs of binding posts internally, so I am not even sure how much power a second pair of (maybe tube-) amps would require for the tweeters... so right now my only solution would be to use two identical pairs of mono amps, but I think that would already be overkill for the tweeters, as they are 170W each and the entire idea was anyway to mix it up with some tube amps. 1st world problems !! :)
Great topic as always
As someone who taught acoustics and worked in the pro audio industry for some 15 years, Gene DellaSala is spot on. Heed his advice.
Yep.
But, if we do not listen at crazy levels. He says if you use the impedance selector switch, it will limit current and you will get only 25 Watts. I barely listen above 90 dB. Even with low eff. Speakers, do you think it will be alright? Talking about a small 2 way 4 ohm bookshelf speaker.
@Dan Wipper hi Dan. I'm new to audio so apologies if this is a stupid question. At 3:15 there is a screen shot of a yamaha A-S801. The switch has 2 options 4ohm A or B/ 8 ohm A+B. Can you explain what this means please.
@@danconnor3089 It means for 4 ohm speakers you can run only one set at a time (either A or B) and for 8 ohm speakers you can run two sets simultaneously (A and B), since two pairs of 8 ohm speakers running in parallel creates an effective impedance of 4 ohms.
I love how you assume what their speaker sensitivity is. How is it? You know what audio level they are listening at.
I ran 4ohm Cerwin Vega monsters on a midrange Denon. The Denon still works (it runs rear channel duty these days).
The very best tip I could give to a up and coming audio enthusiast is to learn about ohms. Parallel and series wiring is a absolute must know. This goes for car audio and home audio. It is the most basic knowledge that you must know.
Ditto ditto! (Couldn’t resist). 😜👍🏼 I never thought about it, but I agree. That is great advice. Differences between parallel & series circuits, and impedance/ohms. Had to get to a library to educate oneself when I was a preteen. Loving the internet!
I always thought that as long as there wasn't an abnormal amount of smoke it should be ok;-)
Yeah...normal amounts of smoke are OK, abnormal amounts are not.
I just ordered pioneer avr with the 5.2.4 so i can have the 4 atmos. But just noticed this morning it is 4 ohms. My current avr is 8 ohms. Checked my speakers they are rated 4-8 ohms. So i am actually hoping this new pioneer one with 4 ohms will actially make my speakers sound better.
On another note..love your jim and spock life sized cut outs.
Excellent video.
Great video very knowledgeable
Excellent advice
Great video! I have a question though. Since you were saying that about 8 ohm to 4 ohm, is there any way for me to run my 4 ohm DVC 12" subs on my receiver if I wire them to 8 ohm? Any help would be greatly appreciated.
7:20 "mid ranges more chocollately" is something I'm going to start using way more often now
Using avr denon 6500h to drive monster vintage SDA SRS 1.2 polks and so far so good.
Gene but what about the other side of the equation with a beefy AVR like the Onkyo TX-SR 805? I have an SVS Ulta front soundstage. Towers and center, all low ohm (4-5) rated through testing. That AVR weighing in at 51 lbs with a big e core transformer), should have no problem driving them, right? I also have an Onkyo HTR 940 driving the rear surrounds, also a semi beefy receiver (rated at 100 X 7 for real with testing) drive the four rear surrounds without issue, right? Please advise.
I used a cheap Pioneer in my garage with some vintage 4ohm speakers. It never ran hot but it started a pretty loud hum when running after about a week.
I am running 4 ohm Jamo D7 speakers on Yamaha Z11 which is set to 8 ohm according to your review years ago. I recently changed the connection to bi-amp to the front left and right. Do I have to keep the same 8 ohm setup on the receiver after bi-amp connection? Thanks
Hello thank you for the video. I have an Onkyo TX-8211 which is stamped min 4-16 ohm and I’m using a pair of HECO speakers from the 70’s that are 4 ohm. I’m only using those alone. Do you think I’m doing any harm on either end?
Hi Gene, after years of money saving, I finally got the my Marantz 8015, it's great and i really love it!
Currently I have a pair of Klipsch 6000f (the new tweeter version) as front channel and a pair Klipsch 160m (the old tweeter version) as surround, but I don't have yet a center (so it would be a 4.1).
You think it's right to use the Marantz 8015 with the 6000f together with the 160m, and for couple of months WITHOUT using the center channel channel or I may damage/stress the my new Marantz?
Thank you in advance for the help.
Thanks for that. I wanted to ask is selecting 4 or 8 ohms in the avr menu, the same as the selector switch that you were alluding to ?
Question. If I want to run my 4 ohm speakers off my old Pioneer 5 channel Receiver would this really be an issue if they were just computer speakers? Volume doesn't have to be too loud as I am right in front of it while working at my desk.
very good video. It gives answers in short period of time. excellent job.
Please can you inform us about videos or articles in which you have reviewed entry level av amplifiers (like Denon AVR-X1600H, Sony STR-DH790, Pioneer VSX-933 Onkyo TX-SR494 and Yamaha RX-V585) and small size speakers for small size rooms (10''x 10'')(3x3 meters) and bigger rooms as (15''x15'')(5x5 meters).
You see there are people with small size rooms and small size budget.
Please can you help with a piece of advice ?
I have an Onkyo TX-RZ720 (Power Output: 175 W/Ch (6 Ohms, 1 kHz, 1% THD, 1 Channel Driven, IEC)) amplifier which I had LG 12ohm speaker connected to, and sounded terrible. Due to limited budget, I decided to get Kicker 3way DSC6930 6x9 (90w rms and 360w max) connecting 1 speaker to each channel. It does mention high current power to drive 5 ohm speakers. What are your thought on this? Will this be better than the LG 12Ohm speaker setup and I am I risking damage/power output to speakers?
Hello Gene, greetings from Colombia. I have a Denon AVRX 6500 H with two floorstanding 4 Ohms Emotiva T2 first generation. Also I bought an AC INFINITY T 10 to help it with internal heat. Actually I’ m operating the Denon with the Auto mode. Do I continue that way ? My Denon can drive those speakers without affect it’s longevity? Thanks for your videos and advice. I appreciate very much your knowledge and experience.
Gene, I'm curious how the Sonos Amp can be recommended to run 6 of the Sonance for Sonos speakers?
this week I'm going to be hooking up my totems dream catchers to my marantz PM 5005.
Serious question:
I have the Denon H3500X, and all Parts Express speakers, all of which speakers are rated at 4 or 6 ohms. I set the Denon for 6 ohms. Should I just reset it to 8, and not worry about it?
I have a Marantz 4270 4 channel (70w x 2) and (25w x4) It was manufactured in august of 1975. I have a pair of Cerwin Vega D9 that state on the speaker, 4-8 0hms. Do you think it is safe to drive these 350watt Cerwins with that Marantz 4270 receiver? I have read a couple places that it would NOT be recommended to run speakers that reach 4ohm on the Marantz 4270 receivers. Any help would be appreciated. Thanks
At the risk of encouraging energy inefficiency... Tubes rock! and they're kinda weird, they have some special relationship with current, where modern amplifiers swing voltage, tubes swing current, I don't fully understand it. Tube amps then have different output taps for different impedances, and pretty much the same watts into the different loads. I saw a debate recently, where someone asked where they should plug in their 6 ohm speakers, into the 4ohm tap, or the 8ohm. The answers were totally bifurcated. No consensus, and even I, the great knower of things was logically torn on which way to go. Maybe you could do a followup for tube amps, and tube hybrids.
I got a 70lb beast of a tube amp used for $1700. I'm considering doing that twice more and running a surround system on them. The problem is, they're RCA, the new model is XLR, which feels like a better path to take, especially as I'm considering using long interconnects to locate them around the room. The debate of longer interconnects, or longer speaker cables, is a good topic to explore too. Sub harmonics were once scientifically thought impossible. But there was some research study that came out recently, which found that higher frequencies can harmonically manifest lower octaves! (will try to find it) Which means that filtering high frequency noise beyond the audio band may actually affect lower frequencies. Which I feel may be an important piece in explaining cable audibility, as the subtle capacitance and inductance of cables effect inaudible high frequencies, that create emergent phenomenon in standing waves in the reflections between speaker crossovers and amplifier's damping factor. Which may explain the observed phenomenon of cables. As it stands, I think the affects of cables are really affects of the amplifier-speaker damping-factor relationship, and whether that affects feedback-based-amplification, and that cables ever so slightly buffer that relationship. All I'm saying is that I'm looking at some interesting stuff, that may explain some stuff. I think scientifically, we may have to start measuring whole systems, and the affects of cables in them, rather than just measuring single cable lengths. And by WE I mean you Gene lol, your whole life now revolves around disproving a negative lol a topic I know you've delved ad-nauseam. But I think resonance between driver's/crossovers and amplifiers, and then the standing waves of them in cables, may cause audible effects with amplifiers of lower damping factor. So if cable affects come from basically being an extension of the amps damping factor ( from cable resistance, induction) then that could explain allot. Suddenly that higher resistance skinny single strand of snakeoil, is a resistor reducing oscillation between the amplifier and the crossover. If a wire is a tunnel, we know that when you drop a pebble in a tunnel it amplifies the sound, lasers amplfy by bouncing between mirrors. Maybe there's something similar going on at high frequencies in wire, something that inductance and resistance would mitigate, or some airy highs that capacitance would sparkle to life. Anyway, I'm just being open minded, these are my own thoughts btw, not some advertised nonsense, sorry for being long winded, you know how I is. ;P
@Audioholics I recently got a Denon AVR-3808CI from my brother in law who recently replaced it with a Denon 4700H. I thought about using it strictly for 2 channel listening and the streaming ability. My speakers are 4ohm nominal impedance, Klipsch Forte I rated at 100watts continuous. On the back of the 3808CI ( 7 channels x 130 watts)it says for use with 6-16 Ohm speakers for . Since it has so much power would it be okay to use for a 2.1 channel set up with the 4 ohm speakers. It weighs 35#'s. Should I stay away from it? If it wasn't free, I wouldn't be asking this question. You guys did a review of this AVR back on 7/3/07.Thanks. Live long and prosper.
Gene I really want to buy the New Polk Reserve R 200s but only have 2k budget for the whole system. I was going to go with a emotiva Pt-100 and a crown 1502 but the Pt-100 is having issues hooking up to my Samsung TV. The TV optical out isn't being picked up by the Pt-100 I saw a post when I asked Google Emotiva Pt-100 and my tv. I can get a Yamaha Rxa2a for 600 bucks. But don't think it will be strong enough for the Polk lsim703s or the Reserve R 200. What do I do ?? Thanks
Need help please!!!!
I have SB CH73 Panasonic speakers. Which amplifier should i use to play the two speakers. The stereo amp section showed 4 ohm 2x53 W RMS. PLEASE HELP!!
I'm powering my Martin Logan Motion 40's (4ohms) with an Arcam SA20 which is rated at 150W per channel at 4ohms. I've never had any issues. Should I be concerned?
I got Dali 505 speakers. They are second hand bought. What amplifier should i use?
It's good to be cautious. Avoid the combination if possible. That said I've done it several times and have had no problems. The receivers never got hot. However, I never turned them up much. Just low level background listening.
I’d love to buy the magnepan lrs speakers which are 4 ohms ... I have a marantz sr7013which is not a cheap receiver . I use it for 2 channel music and 5.1.4 for theatre . Would you think the amp would run the Maggie’s ?
100% true, also there is speakkers rated 8ohms and they actually have under 2ohms resistance 50-150Hz. 🤠
that's a very bad speaker design then, bad crossover particularly.
Actully it's great design all other way, mgnetoresistive-panel not want to point finger 🙃
Is it the same with integrated amplifiers? Some models claim they can handle even 2ohms like NAD amps.
Plenty of integrateds can handle any speaker out there. The McIntosh MA12000, the Music Fidelity M8XI, the Krell FBI, the Hegel H590, Devialet, Naim, Parasound, etc., etc.
Thank you so much because I was thinking of pairing the 4ohm Polk Reserve series with the Denon 2800H, so that's probably a bad idea hey?
The "quote" about smoke and electronics is great.
The average home system amplifier shouldn't be expected to perform well below 8Ω. The damping factor in the cheaper amplifiers really gets bad below 8Ω.
It is better to buy a powered subwoofer than try to get good sound from an overtaxed amplifier.
Can you use external amplifiers and the receiver strictly for processing to get around this issue @audioholics
Well said.
Great video! When you say in parallel you mean more than 1 speaker on a single channel? I have a pair of B&W 603DM S3 towers and just ordered the Sony STR DH590. Should I be worried...? As I can change my order if needed.
yes I mean connecting 2 speakers to a single channel in parallel.
Gene how do you feel about the Yamaha RX-Z9 with 4 ohm speakers? I know you did a very favorable review of that receiver way back when. I have mine driving seven 8 ohm Polk RTxxi series, but once got my hands on some 4 ohm Polk LSi9's and used them as my rear surrounds (set to "small") with the Z9 on the 8 ohm setting. I listen very loud and while I had no thermal shutdown and everything sounded normal, it turned the music room into a sauna! The Z9 I guess has a reputation for heat generation even under normal circumstances.
The Z9 can drive 4 ohm speakers all day long. Very stout amp section. It runs hot bc they turned the heatsinks horizontal to save space. That's really bad for hest dissipation, unfortunately.
Thanks for the explanation! I thing Im in trouble... Im trying to get Atmos going for really cheap and ordered the cheapest 7.2 receiver and 5.1 speakers I could find.. The Sony STRDH790 and JBL Cinema 610 system, The JBL is 4ohm but the Sony says 6ohm... Do I need to get different speakers?
No, it is all volume dependant. Don't try to recreate live rock music and it will (should) be fine. Also a quick non-engineer, non-technical way to check on your new gear is to listen to a movie at the volume you want, then halfway through put your hand on the receiver. If it is quite warm then you are pretty much at your limit. That would be your max volume for movies. If it just lukewarm then you are not stressing out the receiver. If it seems hot at all to the touch then you must turn the volume down or the constant high heat over a few years will shorten the life of the unit. This is very broad brush method, but very easy for the average guy to do to see if he needs more power. The easiest way for the average guy to buy a receiver is to get one rated at 4 ohms without the dreaded 4 ohm switch. Then your receiver really is a 4 ohm receiver. Again, this is a broad brush non-high tech way to see if you are overstressing your unit.
Yep. Bought a pair of Martin Logan 60XT`s. 4 ohm rating. Hooked to a Yamaha RX497. 75w rating. Cuts off many times. Use a Yamaha A-S801. 100w rating. Runs but, very hot to the touch. Finally use a Yamaha A-S1200. 90w rating. Problem goes away. Thing runs just barely warm. So, watts are not the answer. Power supply, caps, heat sinks are.
Nice pec bounce!
Well said!
I use a Hammond 1642 SE output transformer with its 4 Ohm tap to drive Magnepans. But I use a radio station transmitter tube run gently at 1000 Volts on the plate which I am sure is more than enough power. It is more than loud enough if I turn t up too high. But this is very different from a solid state amplifier.
Don't the cables-with-batteries (tm) keep the smoke to a minimum?
Hello, new to the channel and new to stereo equipment.
I have bought the sony str-dh190.
I have 4 Klipsch speakers. All of them are 8 ohms. Is it safe to connect all the speakers and run the receiver in A+B?
Gene, you gotta test a pro amp vs hifi amp
I thought putting speakers, any that are bass or subwoofer speakers, in parallel is bad anyway because it plays around with the tone of those speakers...so it could raise or lower the passive crossover points...essentially the speaker plays in a way that it's unintended. Is that true?
Any help would be greatly appreciate, I am really new to this, my dad gave me a a pair of Polk Audio LSi9 speaker and and the lsic center. I have a pioneer VSX-LX102 and and it is running the speakers well I guess. Should I upgrade my receiver? I mostly play Xbox and watch movies not sure if that matters.
Hi ..i have a question...i bought 4x4ohms 1x4ohms central and 200watt woofer from jbl. I would like to connect it to my macbook pro and not pay a fortune for amplifier. Any suggestions? I live in Germany( shipping😉)
OK, what about playing a Cerwin Vega RE 25 6 ohm speakers with a set of Fluance 8ohm speakers with a Technics SA 303? Will that work? Please Reply THANKS.
Apparently I have a super receiver because I hooked up four 15s and crank that up as high as it will go and nothing happened to the receiver instead of the pictures fell off my walls 🤣🤣🤣
Toughest amp i believe ive had is a yamaha m4, i ran a set of klipsch fortes and infinity kappa 7 pair and i mean ran them hard and the yamaha didnt flinch or even excessively hot, i was really shocked, keep in mind this was all 4 speakers at the same time.
I have a Yamaha AX-930 2 channel integrated amplifier (manufactured 1990). It is rated down to 6 ohms. RMS power 130W per channel/Dynamic power 300W @ 4 ohms. I plan to hook up 2 Cerwin Vega RE30 4 ohm speakers (RMS 250W), as this is the equipment I have. Can I offset any issues the amp might have by running a couple of computer fans set in exhaust mode on top of the amp grill above the heat sink. This would remove much heat and thus avoid overheating. As long as the amp components stay cool, does this offset any problems caused by the amp having to provide additional current?
Also, I am buying new cables (GearIt). Does wire gauge have any bearing on any of this? I have ordered 14 gauge pure copper wire-2 runs of 15 feet. Thanks for any help. Your channel has great content-very helpful.👍
I got all of the steps setup correctly right off the bat. Didn't have to change anything😎😎😎.
Any recommendation for an amp with around 100-150w at 4ohm?
Some receivers will pop the fuses or go into protect when at an "extreme" resistance.
What about tube amps. I have 4 ohm taps on my Rogue Audio but I have to go inside the amp to change them manually. Should I still leave it on the 8 ohm taps.? I only have one set of speakers that are labeled as 4 ohms but I use those with a different set up using a solid state separates amp. I was aware that 8 ohm rated speakers do dip. I just always tried playing it safe with tubes. Would be nice to know if I really didn't need to change them with your recommendation with solid state.
I am also looking for the same answer, if anyone can help us out. I have a tube power amp with taps for 4ohm, 8ohm and 16ohm. Is it safe to connect the 4ohm speakers to the 8ohm/16ohm tap?
If the receiver is any good it’ll turn off before any damage or fires
Cheap receiver will shut down and won't turn back on....they won't catch on fire, but we have experienced many customers that damage the receiver.
@@msabbarese1 i had a shitty reciver on my 2 ohm subwoofer in a 8 ohm channel and it just fucked the channel up but it still works
Hello. I recently got a set of vienna acoustics speakers and currently have marantz 5009 I want to upgrade my reciver that can handle 4ohms,Sonos,and 4k. And my budget is $2,500. Is it possible?
I just ran into your video and I have a Denon Dra685 series that will run 4ohm all the way up to 16ohms and so what are your thoughts about that receiver.
The receivers that say they can run 4 ohm speakers typically have an impedance switch to Pass UL for low impedance loads by cutting the power down to 1/2 or less. I wouldn't run 4 ohm speakers on budget receivers. Flagships like the Marantz SR8012 with dual heatsinks can do it much better.
So a Yamaha Adventage A860 is a budget product. I had the A830 which is an older version, but same power delivery and it was okay until I got an Anthem MRX 300 and it completely put my A830 to shame. After that, I only buy Anthem AVRs now. No more big name brands for AVRs for me anymore.
I've the new Yamaha Receivers r-n602 and r-n803 running my 4 speakers JBL 8 ohms. What happens it that... I bought 4 new Yamaha NS-777 (all are 6 ohms).
What I have to do to connect the Yamaha's stereo receivers (can I put 4 ohms or 8 ohms) to the Yamaha 6 ohms speakers? I never get that kind of answer on all the Internet for 2 months trying, neither by Yamaha. How to connect 4 (yes, 4) 6 ohms speakers to a Receiver (stereo), usually 8 ohms. It's better to try to put all the receivers (stereo) into 4 ohms to run 6 ohms speakers or to put the receivers into 8 ohms? I don't think my new Yamaha stereo n-s602 or 803 has a way to put into 6 ohms. What will be safe for me (sometimes I use low volume and full Loudness to hear my musics, but sometimes I use high volume... I love BASS, and a little middle or high frequencies. Using my other Yamaha, the n-r700 with my 4 JBL S-312 (8 ohms), and the receiver set into 8 ohms, it's all okay (I can have both low and high volume for hours). But now, with the Yamaha's speakers NS-777 (all 6 ohms), I don't know what I have to do. I'm very loss here. Can you help me, please? I love your explanation here, but because I have more than 65 years and always use 4 (four) speakers at once, I'm really loss here. Thanks.
Ya I saw the Sony 190 reviews an Andrew and Sean's videos too. Lol...
I think Sean explains exactly who and what the sony amp is for
Sean did say it is recommended for 6 ohms and up.
Both of the reviews for the budget Sony clearly stated not to go below 6 Ohm.
where is the link?
A cheap alternative is to add a proper value capacitor before the speaker (if it is not subwoofer/ need not produce low frequency
Pure power amplifiers (or integrated amps) are ALWAYS BEST when driving speakers - from power/drivability, SQ, robustness, and fail-proof/simplicity standpoints. Most receivers (even "TOTL" models) have too many compromizes in their power supplies, designs, and layouts to be competitive with power/integrated ONLY amps - because they have to fit all of the power, signal, and digital circuitry all inside of ONE CASE. All those mis-matching power and signals going through them (high voltages, low voltages, signal voltages, digital signals, hi and low currents, etc) automatically causes many problems with interference, isolation, and signal/voltage/power bleeding into wires that shouldn't be passed on them. The more I think about it - the more I lean towards separates ONLY. Reasonably-priced separates will sound better, perform better, and last longer than any one box solution - not to mention being more flexible in setup and upgrading.....
You and ZF should join forces. Maybe between the two of you can can come up with an original idea.
Hi, I purchased recently Sony STR-DH590. It's requires at least 6ohm speaker. But I have small 3ohm speakers (Sony home theater speakers). Can I connect 2 3ohm speaker in series or should I purchase bigger 6ohm speaker?

Ok….so you are the guy who can possibly help me with a question that nobody really seems to have the time to help me with. I bought a Pyle PMXAKB2000 karaoke mixer thinking that something idiot proof would sound great but nowhere seems to have a recommendation for speakers. So with all your knowledge about cheap amps….do you have a suggestion on type and brand of speaker I can pair with my amp? Please
Gene, good video but you can help consumers by providing a list of receivers in various budgets.
Also, what is cheap or not in this discussion?
Flagship Yamaha avr has also problem with 4ohm speakers?
@Jingle Nuts RX-V3067
If i look at the user manual, he can drive only the front speakers with 4ohms but i have the center and the two surrounds speakers also with 4ohm,till know i never had a problem,i guess if i drive all of them higher than 75% of the volume, than i can have a problem..
Thanks for your answer!
Just put two 4 ohm sets of the same speakers in series, problem solved, lmao.
Careful with that Tribble man!!
I run 4ohms into a Yamaha A-S801, the heat sinks in this receiver as massive
I literally learn everything I know from you. Thank you! What about 6 ohm? Just got JBL Studio 590s and wondering what my Pioneer elite will now do. Thanks
My old Denon 1909 can drive my JBL Studio 590s but if I hook up the center channel 520c to it it shuts down. Getting an X3700H tomorrow to fix this and will probably add a 2 channel external amp soon.
Enjoy the 590's. I know I do! Also look into the matching 550p subs when on sale. They are terrific for the $189 I paid a piece.🤯🤓😎 also research criss-crossing the speaker tweeters in an unnatural looking way because it makes the speaker sound terrific. New record day has a whole video on this I believe geared towards the 530 JBL speaker.😉🤗😇
Probably not much, most cheap receivers or amps have digital/tripath amps that usually handle low ohm speakers and are only limited by the power supply. although, I may be talking about stuff "too cheap" to review. A lot of cheap gear based on car amps are rated at 2 ohms to maximize the amount of power available on a 24 vdc (+12 / -12 voltage swing).
And those cheap Class D amps don't hold a candle to even used whole house audio amps like the Niles SI-275 or Sonance 275se. The Class D amps' high power ratings are taken at 10% THD. Plus, the WHA amps are generally high-current amps capable of handling low impedance speakers loads of 2.7 ohms. That all but guarantees excellent bass dynamics without stress or strain.....
I was an audiophile years ago I always wondered why companies make 4 ohm speakers. But maybe only expensive speakers are 4 ohms and with a high quality receiver they are ok.
Back in the old days recievers were lower wattage, or more expensive.
And yet, they all sounded better, got much louder, and generally lasted longer. I had a 30w/channel pioneer Amp back in the 70s that would blow away anything built today in the 100w range.
@@randymc61 Me too. Did it happen to be the Pioneer SX6000? That was my first true stereo receiver. I bought it in 1972 thinking it was 100w/channel, but recently saw online that it’s actual power was 35w/channel. Regardless, that receiver was a great one in all aspects. It had plenty of power driving a pair of 4ohm floorstanders. Maybe it’s my nostalgia for my first piece
of hi-fi gear. Ran a turntable & a Reel-to-reel tape deck. That Pioneer had a great sound to me, with plenty of power to go. It had a full rich lush sound related to the speakers. That’s how I heard that amp. Always seemed it was ready for more gain with composure. I loved the loudness feature too. I had to listen at lower volumes in Barracks overseas. The cherry 🍒 was how good it looked compared to most today. Beautiful walnut shade framing chassis. Real wood! Kept & used that Pioneer for 23-25 years.
HOW about using 8 ohm's center of 30--60 power wattage channel with Yamaha AV RX 3050,
With something as budget friendly as a polk s20 bookshelf dipping to 4.5 ohms at 140hz this should be taken seriously. Gene, should recievers that only list 8 ohm and 6 ohm spec be used with some caution? Marantz's 2 channel power amp ($800) does not show a spec for 4 ohm loads.
Can you help an old fart with Yamaha speakers from the 80's NS-4 serial # 41697 which I could not find on Google. Will they match up with the Yamaha receiver Yamaha RN303BL. I live in small apt. around 450 SQ FT
I don't see a link for the Marantz anywhere

2 questions:
1. What benefits are there of 4 ohm speakers?
2. Why are all car audio speakers 4 ohms?
The problems only arise if you're pushing it (power/volume) pretty hard though, right? I've got an old pioneer (about 15 years old) AVR running two large 4 ohm Cerwin Vegas and two small 8 ohm bookshelf speakers and one 8 ohm center. I've had this system running daily for almost 13 years with no problems, but then, I hardly ever turn it up very loud.
correct. CV speakers are also very efficient so you don't need a lot of power to get them playing loud.
