I really don't know. I didn't plan on buying HUGE speakers. My music room setup is in a state that I don't really want to mess with right now. I'm thinking maybe I can use them for home theater if I can fit them in the room. Or flip. :scratch2:
Home theater, though, really demands a third speaker that's as closely voiced as possible to your left and right mains. In fact, depending on how they're built, lots of folks by three of the same speakers for their fronts.
You can't just toss any old speaker in there as a center channel and expect it to work.
Given how excited everyone is for you, I'd recommend you keep 'em for strictly two-channel music.
