I am a new HT-2 TL (L,R, and HT-1 center) owner and could not be more satisfied in the two weeks I've owned them. As everyone has posted, absolutely amazing. I have a 5 x 200w amp and am not using two of the channels and was wondering if anybody has bi amped their speakers and if it made an improvement? Also, would I need to do anything additional as far as crossovers are concerned or are the speakers sep up to accept this? I haven't ever bi amped but I feel the need to give these new speakers everything they deserve.
