I like the Klipsch towers but am not a fan of the center speakers. I think a better choice in that budget would be some Monoprice Monolith THX speakers: a
365C center and some
365T fronts. That center will be miles ahead of the Klipsch center, and since the center is the most important speaker in the system, that makes the Monolith THX stuff an easy pick over the Klipsch stuff, at least for me. Keep in mind that the Monolith THX speakers are intended to be used with a subwoofer.
