what would happen if.....

[gcmarshall]

what happens if one connects one pair of front speakers to the front (A) channel and ALSO connects those same speakers to, say, the surround back speaker connections amplifier. then, if one activates 7-channel stereo mode, using only the fronts and surround backs (turning off the other amplifiers) is that considered a bi-amped set up? in other words, two sets of speakers wires going to each front speaker; one set running out of the front A channel, with the other set running out of the surround back speaker jacks. the receiver would be in 7 channel stereo mode, the connection plates on the speakers would be removed, and only the front speaker and surround back speaker amplifiers would be turned on.

what would the the result of this set up? a fried receiver? improvement, no improvement, unknown, etc.?

"...is that considered a bi-amped set up?"

No. That's called hooking one speaker up to two amplifiers. Can't say fer certain but that's not the way things work. You're flirting with the possibility that neither amp will work, either now or forever.


Biwiring or passive biamping means sending the same signal to both parts of the speaker. Biamping (or biwiring, for that matter) requires a speaker with fwo sets of binding posts, one for the bass and the the other for the mid/highs, that are normally joined by a removable jumper for a single wire drive.

If you ARE usuing bi-wirable speakers with the jumpers removed, let's hope there are no internal connections between the two areas. At best, you will be getting the half of the surround information from the same box that youi're getting half of the main R/L signals.

If nothing else, it will create a "bizarre" effect. Which channel gets the bass speaker and which gets the highs?

I did that at work with some Monitor 70's and an Onkyo 701 and there was a big improvement in sound! They hit a lot harder and louder, it was fun!

Here, I found a picture of when I did it with some Infinity Beta 50's, a PS12 and a Velodyne DPS-10.

And here is when I did it with the TXSR 503, the Monitor 70's and two DPS-10's:

I don't think the Yamaha is capable of "bi-amplifying" the same way it is described here on the Denon 3805:

Bi-amping the Denon AVR-3805 for 240 Watts for the Front Channels:

you're right. technically it's not. i was just hypothesizing. i have no intention of trying it. my thinking was if i have 7 amplifiers in my receiver, why can't i use two of those amplifiers to "biamp" my front main speaker, since my front speakers have 4 binding posts on each speaker. using the 7 channel stereo mode, but with only 2 of the amps activated, why wouldn't this be an acceptable biamp setup?
