Axiom Home Page Forums General Discussion Advice from Axiom Owners Bi-amping M80's with a Denon 3808

I have a 4308 and it is very similar. If you bi amp you will use 4 of the 7 channells to power your front speakers and only be able to have 5.1 surround. I think you would get more power to the front speakers but possibbly not. When you seperate the high and low speakers within the m80's it may also change the impedance from 4 ohm to 8 ohm. Since your receiver will provide less current on account of increased resistance the total power to the speaker will not increase. Check with Axiom to see if the impedence changes when Bi-Amped.

I've had M80s, Bose 601s, Nuances, M22s and Sansuis all connected to my fronts at once!. Soundstage...what soundstage ?

Jason and I also placed M60s on top of M80s. The M60s were inverted...their woofers were up at ceiling level.

Yeah, there was a lot of presence there but we didn't exactly build a line array. It sounded like two separate, vertically-oriented and discombobulated bass images.

But it looked very intimidating and very precarious, as one speaker set was slightly tilted ala tower of Pisa.

Butch, as was said previously, there's no possibility of actually biamping with a receiver which has only one amplifier feeding through several channels. To even start on biamping two separate amplifiers would be needed, as the term implies. Also, an external crossover(with the internal speaker crossover removed or bypassed)before the amplifiers would be needed so that each amplifier would be sent only the desired frequencies.

On your question about a 4ohm speaker turning into an 8ohm speaker, no, each section is nominally 4ohms by itself. 4 ohms doesn't come about as a result of two 8ohm sections being driven in parallel. The action of the crossover keeps the impedance(roughly)at 4ohms.

Yeah, what John said.
