Bi amping

[AVP]

I have a Yamaha rv-x775 receiver and Rf5 Klipsch speakers. I want to bi amp the speakers by using LR channels from from my receivers amp to the hi pass on my speakers. I want to use the pre outs to go to mono amplifiers to drive the low pass on the speakers. Is this doable?

Passive bi-amping isn’t really worth the trouble. Especially with higher sensitivity speakers.
If you want to do it, no harm should come as long as you do it properly.
That said, you really want matching Amps, not using your AVR and a separate Amp.
Regardless, I am a firm believer, after much research and conversations with professional Speaker Designers, that you are much better off using a single Amp channel per Speaker from an Amp capable of delivering plenty of clean power to your Speakers.

I’m lookin at the outlaw 2220. You would recommend 4 for the klipsch? 2+2. Or can I use the Yamaha for the highs, and the outlaws for the lows. Sorry, just clarifying. Thanks

If the outlaw amp and the internal yamaha amps have different gain the bass and upper will increase in volume differently.

I would not recommend Buy-Amping your Speakers. There really is no benefit to it. *shrugs

If you choose to, I would recommend using matching Amps, not splitting between two different Amps.

I use the Outlaw 2200s, single Amp to each of my mains (and Center +Surrounds). They are good Amps. I have never felt I was leaving any performance on the table and have never second guessed my choice to run single Amps.

Did you read his post? Lol.

You'd really want to get four of the 2220s so everything would be gain matched, and for the money you'd spend on amplification you could put toward better speakers. Not that your current speakers are bad, but there are more expensive options with better performance. Higher quality speakers will get you much more than bi amping or more power can.

I agree with what others have said that it is not worth it, not the way you are thinking of doing anyway even if you use 4 M2220. Yes if you use four M2220 to biamp then the issue of different gains are resolved but now you have a new one. That is, the input impedance issue.

The Outlaw's input impedance is only 10 kOhm, so for the Yamaha pre out to feed 2 of them in parallel, on top of the Yamaha's own internal amp, the overall input impedance will be less than 5,000 ohm for sure.

That may be still be fine but Yamaha's AVRs are known to have limited pre out drivability to begin with, so the potential signal degradation when used to feed 3 power amps may not be insignificant. Whatever benefits from (not likely) the bi-amp scheme may not make up for the potential loss in the preamp side.

All great info. Thank you. I’ve been out of home audio for about 12 years. Ive been doing a lot of reading and so much has changed. If I were to scrap everything I have, where would you recommend starting?

A higher end Yamaha AVR.

More accurate brands of speakers. So many depending on your budget.

I was looking at the Devialet speakers, but looks like there are connectivity issues with running them in a home theater setup. I really want power and simplicity which I thought I had found in that setup. Budget around 6k for everything. I don’t need surround. I would really like a badass 3.2 setup. I have an old SVS Ultra sub that I’m still looking for a twin (passive) I’d like to to keep that for the low end.

Wouldn't bother with the passive bi-amping thing either with the avr or separate amps myself. Just as was noted, simply a more powerful amp would be a better choice.
I'd concentrate on speakers then worry about an appropriate amp. Are you talking about those Devialet boom box things? Which old SVS sub do you have?

RBH SVT + SV821C + Yamaha AVR = 3.2 bada$$.

Ultra passive

 

[lovinthehd]

Can't even remember SVS offering a passive! What size is it? Ported? Sealed? Could be hard to match for a second....

 

[AVP]

40” tall. 16” diameter. Came with a Samson 1000. I missed an opportunity not too long ago on eBay. Contacted SVS, and they won’t build mother 1. It was built 2001-02. I know if I got another 1 with a better amp it would bring down the house.

 

[AVP]

3 ports. Came with 1 plug.

For the cost of a second set of speaker wires, you can do passive bi-amping using your current AV receiver. It may not be the final word in bi-amp setups, but it'll let you explore any possible benefits with minimal cost and effort.

[ryanosaur]

Ah yes... Buy-Wiring... Another largely wasteful pursuit.

@PENG , I think you mentioned there may be a case where bi-wiring helps with some impedance issue (???). Would you comment on that please?

I strongly doubt you will be able to do that with a receiver. How will you balance the output of the high frequency driver(s) with that of the woofer? There is no gain control on the Outlaw power amp.
