Hello

Can Anybody advise me if I can bi amp a pair of Polk M-60's with an Onkyo 8555 receiver ( using all 4 channel in a bi amp connections to the speakers)..? there is nothing in the manual to that effect.


a- is it feasible without damaging spekars and/or receiver

b- does it make any difference in sound?


I would appreciate any help


thanks, Pallpoul

If it's not mentioned in the manual, then I wouldn't think so.


But it wouldn't matter much, anyway. Bi-amping is done to provide more power to the speakers by allowing each amp to boost only part of the signal (low frequencies, or highs). All of the amp channels inside a receiver are sharing a single power supply, and that is what limits your power. Dividing that power between 4 channels instead of 2 won't really make any meaningful difference at the speakers. Any improvement would be so small (maybe 1dB of extra headroom) that you would probably not even notice.


The bi-amp capability in speakers is really intended for use with separate amplifiers. Receiver manufacturers often include that capability just to fluff up their marketing literature.
