Since I always enjoy seeing other people's setups, here's mine:
For the record, that's a 58" plasma on the wall. Everything else is so big, it looks like a 32".
The subs are a pair of DIY 18" TC Sounds LMS Ultras in 24" cubes powered by a pair of Behringer EP4000 amps.
I have the amps up in the floor joists just below my listening room. I didn't have room for the amps and with the cooling fans so loud, it's better that they are down in the basement.
My subwoofer progression has been a SVS 20-39PC+ from when they first came out. Then a SVS PB13-Ultra, a Submersive HP, and I even tested dual Submersive HP's. The dual LMS Ultras are by far the best subs I've ever heard. They work perfectly with my room.
My setup is primarily a 2-channel audio setup that is home theater capable.
