Bi amping question

[Merkules2001]

I have a pair of b&w dm604s2 speakers. I have an onkyo nr709 powering them. I tried to use biamp feature on that unit. Set front to biamp. Used correct channel and only got lows. So my question is can I use nr709+m282 on one pair of speakers. I already use zone 2 on another pair of speakers through rca to another receiver.

Short answer is no audible benefit in passive bi amping.

As everettT said, there no audible benefit in passive bi-amping.

In addition, there cannot be any benefit by using an AVR such as yours for bi-amping. It has a single power supply section that provides power for all the individual output channels. Reassigning those channels does not send more power to your speakers. The power supply can only do so much.

Can the engine of a 4-wheel drive vehicle deliver more power to the wheels when 4-wheel drive is selected compared to when 2-wheel drive is used? Of course not.

It is a disservice that AVR manufacturers describe doing this in their owners manuals. One can even argue that it's dishonest.

If you use an additional external amplifier such as an Onkyo M282, you would be able to provide more power to your speakers. However, we are then back to everettT's point that you will not likely hear any benefit.

I'd also figure out what is going wrong now before expanding the passive bi-amping thing...altho I still wouldn't waste the amp/wire doing so.

Yes to all the above...
And:
I spoke with several speaker designers last year when I was shopping for my rig. None of them felt that bi-amping did anything worthwhile. I was surprised as they all put 2pr of binding posts on their speakers...
One of the three does so because he is a firm believer in bi-wiring! I'm not going to name him. And though I think he has a true innovators spirit, his speakers remain in a category of cult favorites as he has yet to allow any third party testing to be published for his most popular gear.
Two of the three put the extra binding posts on their speakers because they are concerned more about their clients possibly selling the speakers in the future and recognize that the single pair of binding posts will hurt resale value in the modern market.
To be clear: Two successful speaker designers only do it because of market EXPECTATIONS. They do not want their speakers bi-wired or bi-amped. (Though one said he will tell people to bi-wire if they want, not suggesting improvement, just saying it can be done with no harm to the drivers.)

And again: All felt Bi-amping was meaningless.

Hmmm.

I spent a lot of time looking at that concept last year: Passive Bi-Amp, Vertical or Horizontal... To do so from your AVR is Pointless. To do so from a multi-channel external amp, unless the amp claims All-Channels-Driven specs, is also pointless.

If you want to really do the job right, consider getting Monoblocks for your mains... give each speaker their own good quality, clean, power supply. Enough to hit Reference Level Dynamic peaks (105dB). For me, that was about 256w. The Outlaw 2200s are rated conservatively at 200w into 8ohms/300w into 4. I likely never even come close to using that... though its there if its needed. (I run 5-channels that way... Rears are on my AVR, as will my Atmos when I get around to it.)

Thanks folks.

They work fine with the connectors between the plugs. I had read to remove those or fry your amp.

Try reversing the wires for "hi" vs "lo" (they're both the same anyways).

I will. Thanks.
