This has been a great thread! Props to all those killer systems pictured!
Here is my little setup:
This is our first house and we have only been moved in for about two months now. The room is a little small but it will do - it is certainly better than the apartment we used to have!
Here is the front. KG.5s as mains (small but effective), KV3 center and a Velodyne sub for now. My wife and I agreed that she could have the whole rest of the house if I got the living room and the garage. That seems to have worked out well. She has not complained one single time about all the little black noise boxes. The TV is a Sanyo 32" HD. The cat is an 8 y/o tabby with an attitude.
One of my prized possessions - this is a DIY rack made from polished aluminum extrusions, brackets and stained birch ply with edge veneers. It is part flexy rack, part something a little nicer. More pictures of it are here: http://home.hiwaay.net/~lbrewer/images/rack/
Matching DIY speaker stands. Different tubing, same wood. The wire is run up through the middle.
Rear KG.5s for the 6th and 7th channels.
View from the front corner showing more .5's as left and right surrounds. The wiring for the surrounds is Belden 5000U, 12 gauge. All of it was run in wall - quite a chore in Alabama heat.
These are the brackets I used to mount all four surrounds. They are from some type of JBL monitor speaker. I took off some unused brackets and was left with a 3/8" stud that screwed right into the back of pre drilled .5s (Thanks Klipsch). Wire runs up through the mounts. Each mount was rotated 45degrees so I could put two bolts into the studs.
The last shot, from the right rear. A matching TV stand with integral drawer and center channel shelf is in pieces out in my garage right now. That, and some wire tidying, should make it look a little better.
