I have a Denon 4311CI that I will be moving over to my new 5.1 setup with 5 of the B&W CM1 speakers. I'm a newbie when it comes to setting up receivers beyond stereo mode (previously it was just on a 2.1 setup). Should I take advantage of the bi-amp capability in the 4311CI and wire the tweeter and the midrange speaker on the front CM1s separately (removing the metal bridge on the back of the speaker)? I am in the middle of running 14/4 wire to each CM1. Does bi-amping apply to just the front left and right, or also the center speaker?
