Custom-built center, with SL3-derived ESL and mid-bass line-array. Bolted to top of 4x15" Infinite Baffle sub. Full acoustic treatments missing from pic, as is AT screen that sits in front of it.
I fully expected to have to take down the screen at some point in the last 16 years so I can take fresh photos of it and now fully treated wall behind it, but no, that darn thing just works perfectly year in and year out.
