Hey, I have monitor audio bronze 6 tower speakers and they are hooked up to a 5.1 HK receiver. I am running 5 speakers, a monitor audio center channel and 2 old cheap surround speakers with an polk audio psw125 sub. I was thinking of bi-amping the tower speakers to increase performance. Do you think I should? also how would I bi-amp them with a 5.1 receiver. i found i would need a power amp but i do not know how to integrate that into the system.
