Here is my situation.

2 identical pairs of speakers, one pair on channel A the other on channel B. Channel A and B: all surrounds and center shut off as is the sub. speakers set to large and Xover at 80 ( though I do not think this matters in large). I then listen between the speakers and channel A has no bass, and sound boxy, but B sounds great. I then switch the speakers and the same, A = bad B = good. I then Biwire and the speakers sound bad, like they did on channel A. Shouldn't A and B sound the same??

I brought it in to get looked at and the guy said I had the sub turned on(which I did not), so I took it home and it still sounds like crap. Any ideas? This is deffective is it not?
