I have a question in an area I'm not too knowledgable about concerning the M80's.... since there are two sets of terminals on the back of the speaker (connected with a gold plated bridge) I was wondering what the effect of running two wire runs to the speakers would be and removing the bridge. Say for instance, I ran one wire run from the Emotiva to the bottom posts, and then another run from the Denon to the top posts, what would this do? I believe it's called 'bi-amping', but what is the positive or negative effects of doing this? Would this turn them into 8 ohm speakers? Do the bottom posts only feed the bottom two drivers and the top posts feed the top four? Or is it three and three? Or is there any separation at all if you remove the bridge and run them from separate amps?
Excuse my ignorance in this area, I'm just curious as to the possibilities of having the four post arrangement like the M80's have.

It would be bi-wiring. And it would cost you more. That's about all it would do.

Using two separate amps to power one speaker is bi-wiring? Then what is bi-amping?

whoop, you're right, that's bi-amping. But it really wouldn't do much, if any good. There's another discussion going now in the Tech forum. Or the Advice forum. Dunno, I'm drinking scotch.

You only really get a benefit from two amps if you have an electronic crossover before the amps that just sends low notes to one amp and high notes to the other amp. Without an electronic crossover you're still amplifying all the signals in both amps so you're not really gaining anything. Then again I always thought the best thing about bi-amping was being able to crank the volume until the amp driving the woofers was clipping like crazy and still have clean sound coming out of the mids and tweets IIRC the lower set of terminals on the M80 goes to the woofers through the woofer part of the crossover, and the upper set goes to the mids and tweets through the mid/tweed parts of the crossover.

Bahahaha hahahaha hah hahah ah ha hahahah!!! IIRC the lower set of terminals on the M80 goes to the woofers through the woofer part of the crossover, and the upper set goes to the mids and tweets through the mid/tweed parts of the crossover. Ah, I see. This is what I suspected. So again I ask, by splitting the woofers from the mids/tweets wouldn't this change the ohm load? Wouldn't one amp push an 8 ohm load to the woofers and the other amp push an 8 ohm load to the other four speakers? Or does it work that way?

No, I don't think it changes the impedance. I know that someone has the technical answer, and I've seen it before, but I don't remember what it is right now.
Useful, ain't I?

Given how my morning is going (not to mention the threads in this forum), it seems like a good idea, don't it?
