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.
