You nailed it! Depending on 3 things: speaker sensitivity, desired listening volume and crossover point to subwoofers. 55 watts per channel RMS at low THD can be more than enough power. It is a multi variable equation. Short answer: it depends. Great job explaining.

For me, it made a noticeable difference. I was running a 7.3.2 With a Marantz 7015 receiver. I have Klipsch RF7 IIIs and an RC64 III on my front soundstage. Also have RP8000f towers In the rear. I put an Anthem 325 on the LCRs. It did wake them up. But it woke up the mid range in the rear/heights even more. I assume because the LCRs were no longer stealing all of the power LOL. Not just a headroom improvement, but improved detail too. I'd say the hungrier, higher quality speakers will yield the most noticeable difference.

I have a 100wpc Onkyo receiver with Klipsch in a 5.2 setup. About 13 yrs ago I got an Emotiva xpa-3. Had to send it back due to some humming I could not get rid of. In all honesty I could not hear any difference ( minus the hum ). A better sound stage. ( maybe ) I'm thinking that an external amp may be a waste of $. With my low to moderate listening levels and the efficient speakers, It's hard to justify. Even a BasX Emotiva amp, I don't think I'll hear an improvement. Any thoughts out there ?

Great video Michael! I was just thinking last week how I missed seeing these types of videos on your channel!

And keep in mind 100 watts vs 200 is only 3db. At loud volumes noticeable but dint expect it to be like whoa!!! I went from a 200 to 300 per channel within the same brand as I expected at loud volumes noticeable. Reg volumes not so much. I've had alot of power amps too. Dont let price make you think you are necessarily getting a better amp either. Emotiva ATI outlaw have performed as good as parasound halos, aragon. Levison, and other high end amps I've had.

Thank You. This one question asked and your answers provided has help me and a host of others greatly.

I have an Emotiva XPA7 hooked to an Arcam AVR11. I noticed a huge difference right away. Not only were action scenes more dynamic but the clarity was much better.

Thi s was a Fantastic explanation! Great video!

I don't remember the receiver I had, but I added a 5x200 watt Outlaw amp about 15 or 20 years ago. The speakers were small Tannoy PBM 6.5 studio monitors. The improvement in sound quality was dramatic. The amp was a good value. I'm still using it, but I'm on my 3 processor and 3rd set of front speakers. In all fairness, the speakers were fine until my 2 year-old thought the aluminum dome mid-range was a button and kept pressing it. :( I've never had a $6000+ flagship receiver, but compared to the amp in a sub $1000 receiver, an external amp is a must. And now, you can get a decent amp for a pretty good price. However, If I were starting from scratch, I'd likely use 3 powered studio monitors for LCR. As an audio engineer, I really love the flat and accurate sound that studio monitors give. I designed a home theater for my Dad 20 years ago with all Genelec monitors and it's still as good as a post production sound stage - it was REALLY expensive, not a bad value when you consider how long it's been.

Thanks for the excellent explanation. Not alot of people know that. I like also that like emotiva they show that their amps show that all channels are driven with their amps. Thank you Michael.

i returned the first LX505 because the chip had gotten corrupted as a result of a speaker wire short. Got the replacement and have been very pleased. But then I ordered and connected a Tonewinner AD7300PA + and have been even more pleased and impressed, I do wish I could control the crossovers independently and the subs were separated but those aren't deal breakers. In Australia the Onkyo RZ50 was 200.00 more than the Pioneer. I've had no trouble getting into the menu. If i would warn about anything it would be about speaker connections and wire shorts, which can be potentially disastrous

Adding just a stereo power amp for the front speakers is usually the most VFM upgrade as about 50% of the sound in a 5/7 channel set up is delivered by the front left and right channels. Stereo power amps are a dime a dozen, compared to 3, 4, 5 channel amps. Most of us have an older stereo power amp in our collection.

Excellent explanation. Thank you :)

Like almost everyone I started with a simple 5.1 receiver several years ago. If you have the budget, a separate pre/pro and amplifier(s) is the way to go. The power supplies in AVR’s aren’t mage to do everything they are asked to do

Nice review question answered, as far as the speakers go it's also going to depend on the speakers ohms rather it be 4 or 8, I am sure thing will also make a difference.

Great video, and agree with the content. However, there are some A/V receivers that do have dedicated power to each channel, that the wattage does not get reduced as you add more speakers. Each speaker output is dedicated, and the power wattage is not split up. My JBL A/V receiver is that way, and is not based on the "2 Channel" configuration as some amplifiers like to use. I'm able to have my surround speakers just as loud or just as much power as my front Right, Left, Center speakers. All speakers get the same output wattage, regardless if there's 3 speakers or 5 speakers connected. But you have to watch which A/V receivers actually do this. Needless to say, this makes for a very large, and heavy A/V receiver that needs plenty of "air".

Just got my first amp(emotiva xpa5 gen 3) with full klipsch 7.2.2 and honestly I haven't really noticed that much of a difference yet. I think only time you really notice a difference is when it's turned up loud.

I've got the SR7015, and made the shift to amplify the LCR with a 3 channel amp. You won't regret it. Just be careful, as in the settings, you can only select pre out for 2 channels, or all channels. No options for 3. After researching I just set it at 2, and hooked up the 3rd as a pre out, and it still works. Front 3 running off of an Anthem 325, and love it.

Great explanation and great points! My upgrade Path on my main system included upgrading the receiver first, then adding a 3-ch amp for the front. Already got the jamming SVS-3000PB subs, Klipsch RP Towers in the Front, and 4x Ceiling speakers for Atmos/Surround. As much as I want to upgrade, it really is enough power to crank beyond comfort. With high efficiency main speakers, even with the LPF off on my mains, which I strongly prefer with good towers, I never notice any distortion or strain. And for music, I use stereo mode, which gives them more power anyways.

Good info. All about caps, capacitors that is. Power supply charges them up for them bombastic events, instant power on tap. An AVR has limited room allocated to: processing, I/O, video, AND must provide speaker power ...whereas a dedicated amp in its simplest form is just a power supply and caps! Thats the efficiency and benefit, the right tool for the right job.

It's not day and night, but it is noticeable. When I had my theater in a 10'x12' room, the SR7012 performed well. When I went to a larger room, external amps helped. With a larger room, you tend to turn it up louder. Also, with larger amps, I seemed to have better dynamics at lower volumes. Some think I am crazy though.

@Al Better sound using decaded Amps at lower volume has more to do with a separation of consurns than watts, manufacturers limit production costs by selecting cheaper parts in AVRs, there's also an issue with crosstalk, but the biggest issue is the lack of current needed to push the signal to the peak before time runs out, this results in the clipping or rolloff of the signal, when a high powered Amp is connected, this is reduced at all volume levels, but maybe more noticeable are higher demands of volume.

Been here since surround sound, then Dolby Pro Logic when you connected it to a stereo receiver. My opinion is yes, be it good old Pro Logic or Digital sound, there is a noticeable difference in sound. Call it Dynamic Range, no distortion and perceived clear/clean sound.

Great video Youthman! You influenced me to purchase 2 5000 watt power amps! I still want another one or two! I will wait till the end of the year, my bank account needs to recover!!!

Bought an Emotiva XPA5-Gen3 a while ago. At this time I had a Denon X4400 and a Klipsch RP 5.1.4 System (280F, 450C, 160M). Long story short, I returned it. I'm usually listening at - 20 to -15. I wasn't able to notice a difference at all. I had it once that I thought the Denon went out of juice, this was whilst listening music at +15 in All Channel Stereo, but this was more or less just a test because thats way above "apartment listening levels". To be fair, I haven't tried the Emotiva at this volume, because it would be an unrealistic scenario (for me) anyway.

Great video - Only thing I'm uncertain about is due to my speakers; RF7 II L&R (101db sensitivity) and RC64 II C and their remarkable high efficiency and is an amplifier warranted. I have a Denon 6400 receiver and i'm considering getting an Emotiva XPA-5 (200 watt per channel) to get more head room and clarity but having such efficient speakers it might not be necessary. I'm running a 11 (7.2.4) speaker setup with 2 subwoofers so I'm sure the amp is diluted pushing all those speakers. I know there are alot of experts out there, maybe even someone with similar setup who can offer advice.

Not the same wattage

When using external amps, does the preamp voltage decrease if you go from front 3 LCR to 5 or 7 channels, all running at the same time? Can an AVR fully maintain its voltage so that the power amp runs at its full potential when all channels are driven at different volumes?

Very happy with my Emotiva A3 powering LCR (and LR in preout mode) with my Denon x3700h. I can definitely hear an improvement. External amplification is a must is using 4ohm speakers in my opinion. Recently added bass traps to first reflection points along side walls. Clarity further improved.

I have cranked it up fairly loud and it still plays distortion-free. My sound system consists of 4 SVS Ultra Bookshelf speakers (2 for the mains and 2 for the side channels), an SVS Ultra Center speaker, 6 SVS Prime Elevation speakers (4 ceiling mounted for Dolby Atmos and 2 mounted on the back wall for the rear channels) and 2 SVS SB-3000 Subwoofers.

Hi Sir I recently bought Marantz SR8015 receiver and planning on buying a pair of RP-6000F and a RP-504C for my first home theatre build. I see that the sensitivity for these speakers is 96dB. So, does it mean if I sit at 4m from the speakers, I still get 84dB using just 1W, given that for each doubling of distance it takes 6dB away? Or to put it other way, does it just take 16W to raise the dropped volume to 96dB again at 4m, having to double the wattage for each 3dB gain to compensate for the lost 12dB? And I don't think I'll ever go beyond 85dB during movie watching. If that's the case, is my SR8015 more than enough for my use case?

Great, informative video. Is it purely down to higher volumes then (i did notice i had to increase the volume after adding 4 atmos speakers)? But regarding your analogy with the cars, does this mean timings can be affected also🤔

It is all about control. The power has to control the conus from the speakers, in other words, more power will control the movements of the speaker tighter. Ideally you want 1,5 times more power than your speakers max rating So for a 150 watt RMS speaker you should want 200 watt rms Amp.

How about for those of us that use our home theater system for vinyl as well and want a great sound?

I am running two old beefier AVR's from Onkyo the 805 for processing LCR and the Onkyo 940 for my SVS Ultra surrounds until I get amplification. Plenty until I get Emotiva or Monolith amplification.

Your speaker resistance is also a important thing to consider when choosing AVRs and power amplifiers ... A 4 ohm speaker will double the workload of a AVR amplifier compared to a 8 ohm speaker, Problem comes from that AVRs generally don't release any more power when presented with a 4 ohm load so in simple terms the AVRs power rating is halved when you have 4 ohms speakers...AVRs generally produce no extra power with 4 ohm loads , cheap to mid priced power amplifiers can generally give about 50% boost to power and expensive amplifiers can become true " double down amplifiers"...

Yeah, it also helps to do a little research using a speaker power calculator. With my MLP distance, speaker sensitivity, etc Turns out at the levels I normally listen to, it was sucking back a whopping....3 watts per channel. At -15db on the dial it was maybe 20 watts per channel. At the very most at uncomfortable levels. Confirmed with killawatt at the wall. Which a decent AVR can handle just fine. It made zero difference sonically, added a small hum to the system that was fun to figure out....but my AVR runs coolers. So yeah, use a speaker power calculator first after determining what spl levels you want to see what power you're using or need.

You can feel some bass hit in your chest and feel the floor vibrating. 5-12W per speaker is like standing in front of DJ speakers at a club.

Youthman, my my Denon AVR X4700H has 9 discrete amps - not a single shared amp.

If your Denon is already loud enough for your space then save your money. Denon promise that with 5 speakers you will get 70% of that 125 wpc. So about 88 wpc with 5 speakers and more like 65-60 wpc when powering 9 speakers. I have the Denon X6700h, I also have a Emotiva BasX A3 powering my L/R/C speakers (Monitor Audio Gold, C350 Centre, and 200 L/R) plus a Emotiva BasX A4 powering my Four Monitor Audio Bronze 100 Surrounds and rear surrounds. This means the Denon only has to power the six B&W M-1 heights. The Monitor Audio are less efficient (Golds 90db and can drop to 4 Ohms, Bronze 87db, and can also drop to 4 Ohms) So in my case scenario it works, but with more efficient Klipsch speakers you might be ok. PS I also have two SVS PB1000 subs, they are good enough for me, and my neighbours. lol

The Amp can only ampfly what's sent to it, but there's less chance of noise being introduced by crosstalk from internal components processing the signal, noise can still be introduced by cables. Any amplifier can appear to affect the sound by running short of power (current) and clipping or rolling off the signal, this can result with damage to the speaker.

Speaker efficiency is a huge deal too...I make it a point to buy very efficient speakers so my amp doesn't have to work as hard to achieve the desired volume level with the same amount of power...most of the speakers in my system have a sensitivity >95db...and it makes a huge difference

Hey Frank. Your RCA’s are always on so you can hook up any channel count, amplifier, and it will work fine. Your AVR will power whatever speakers you have connected directly to it, and the pre-outs will send signals to the external amplifiers you have connected. If you select preamp mode in the Marantz, it disables all of the internal amplification, so you will need external amplification for each channel of your system.

In my case, I have a 11.2.4 set up with the main pre running out to my Luxman c700u's theatre pass through and on to my power amp and main speakers with the Denon powering the other 9 channels. The example you gave of adding a 3 channel amp cannot be done with the Denon 6700 as the only options that are given is to have all channels running, all channels off in pre-amp mode or (as I have it) all channels running except the front main which is in pre-amp mode. My only option is to add a 9 channel amp (or 11 channel if I want to go 11.2.6) So I want to say that, "Buyer beware". Make sure your AVR is flexible in designating which channels are powered and which channel are in pre mode.

And as I have it, main front in PRE and ALL remaining channels driven. So if I wanted to add a Magnepan centre, which would require a mono block to drive it, I cannot assign centre channel to be a PRE and connect the mono block.

If this is true and they upgrade this in the future, the 6700 will show its true abilities. Admittedly, this affects a very small percentage of their customers. In my case it is actually relevant as I plan to upgrade the 1.7's to 3.7iRs.

Жыл бұрын

Answer to your first question, often times it depends on things like the sensitivity of your speakers. If you have high sensitivity speakers, you were here less difference by adding power because it’s already taking very little wattage to get your speakers to reference volume. Answer to your second question, it’s not that AVR’s are 140 W x 2 that’s just the power rating with only two channels driven. That same AVR rated powering all nine or 11 speakers might drop down to only 55 watts per channel.

Youthman, great video. However, there are a couple of very important specs when rating amplifiers that go unnoticed by many people. Looking at the rated watts with 2 speakers driven is the first part but at what ohms? Many amps aren't happy at say 4ohms where many smaller or expensive speakers live e.g. bookies and tweeters. And at what frequency range is the rating? The latter being the slick marketing companies do. If the ratings aren't at the full spectrum of 20hz to 20khz it's snake oil. Period. Many list their power ratings at 1khz ! Even with adding a sub, an amp still needs power to drive the mids and bass frequencies above 80hz. And if you're running your front speakers at full range...smh you got played ! So my advice, do your homework with whichever component you start with when building your home theater and make sure they play nice with each other. Finally, and I totally agree with Youthman, get a good power amplifier. At least a 3 channel or more but make sure your AVR has pre-outs before you buy one. ✊🏼

Whatever camera, lens, and lighting you are using looks very professional

Newb question(s) here: should watts output of amps match watts output of AVR? Put another way, would it be noticeable if you have a 300W pc amp powering LCR when your 100W AVR is powering the rest? Guess I'm asking if more watts going to speakers changes the sound signature coming from speakers or is it only the volume affected?

To answer your question, having more power available for some channels does not change the sound except when the extra power is needed, and you will have less distortion and compression of peaks. The volume control and the content determine how much power is sent to the speakers. If there is insufficient power, the amps will clip and distort. One thing to recognize is that it takes twice as much power to produce 3dB more output. 3dB is commonly considered the minimum change to be easily recognizable as louder. So double the power only gives you the ability to make it very slightly louder. Most of the time your amps are only averaging 1 or 2 watts of output. It is for intermittent, momentary peaks that up to 100 times as much power can be needed.

Your towers will sound more like powered subwoofers in some cases.

Manufacturer website will typically show how much power they recommend. I’m ok using twice their max. So if a speaker is rated up to 150 watts continuous, I’m ok driving it with a 300 wpc amp. It’s better to have too much power and not need it than to not have enough power and the amp begins to clip or introduce distortion:

@@Youthman thanks so much. Never messed with amps before. Trying to figure out what I need has been daunting.

Doesn't klipsch lie about the speaker sensitivity rating how dose that make it more useful

I have an ATI AT527NC powering 7 Klipsch front (280F), center (450C) surround (250S) and rear speakers (260F)...connected to a Denon 4400h powering the 4 Atmos speakers (500SA)...the ping, ting and ching-a-ling is more rich/dynamic than just the AVR alone...but you're not getting anything near using the 200 watts per channel the ATI puts out...without going deaf first....
