I have a home theater setup with four π mains (JBL2226/B&CDE250) and three π subs. The television is plasma so I don't use a center channel. I use an Audio Note Kit 2 for the mains and Profet amps for the subs.In my bedroom, I have a couple of two π towers that I use. I have a wall mounted LCD, so the speakers serve there too. The amp is a Stoetkit.
I also have seven π cornerhorns in my office (2226/Delta10/DE250), but they're not being used for home theater. My living room does not have two corners that would work well, so the fours are in the living room, sevens in the office.
