Uh, I guess I'm included.
7.4.4 in the theater
5.1.4 in the office
2.1 also in the office (PC)
5.0 in the living room
2.1 in the master bedroom
I've got a least another sub and 2 bare drivers that could become subs. Plate amp too. That and the 15 speakers from various systems I haven't gotten rid of for some reason. I'm sure my kids will want at least 5.1 in their bedrooms at some point.
Got a couple of "spare" tv's and receivers too. Too bad none of it is worth anything.
