I see a lot of discussion about subs and mains in this forum. The center channel is supposed to be the most important speaker in HT. I know it is supposed to be timbre matched with the mains. Apparently, just because the mains sound good does not mean that the center will sound good. I have read more than once where the center that matched the mains did not sound good. That being the case, have you ever built your system around the center? If so, what is the best center channel you have heard? If not, why would you base your system on the mains if the center is the most important speaker? I realize that ideally you would want identical speakers across the front but then don't you have problems with horizontal vs vertical displacement of sound?
