Yup. That is the "old work" box. I current have adjustable boxes for the rest of the theater where the box has a metal clamp that attaches to the stud and then you use a screw to adjust the depth. I only have single , double, and triple gang versions of those.

Use two of the double ones on either side of the same stud?

There you go thinking again....

Let me see how that would lay out. I don't think that they could go on the same stud due to where the stud is located, plus the fact that the metal plate from one box would be in the way of the other since they "wrap" around the stud, but maybe put the main lighting (cans and sconces) on the first switch in the room, and then a stud or two back, put up the "effects" switches for the stars and rope lighting...

I will have to look when I get home.

For my project I put in a 20 amp circuit just for the subs and 20 amp for the rest of the equipment. The electrical outlets in the room are on a 20 amp circuit shared with the outlets of a couple other rooms. Then the lights are on their own 15 amp circuit. IIRC I think I put in 7 new circuits for the entire basement remodel.

As for the subs getting their own circuit, I figured one circuit is ~2200 Watts (20a*110v). I may eventually use at least half of that in amplified power.

A few new pictures tonight. I got my backer boxes up for the can lights that go in to the soffits. I also got them wired up back to the light switch. Took a while to get them attached since I didn't want them snug, but just held in place by a few finishing nails until the bottom of the soffit goes in. I then ran the wiring and stapled them in place.

Another shot of the equipment rack area. The blue boxes are adjustable but since they are cut out in the back, I made an entire sealed part around that entire area to keep the sound somewhat contained.

Oh, and the neighbors across the street who had an open house this past week, here is their "theater room"...

I'm thinking of Nelson from The Simpsons.

Sadly, for many people that is what they think a home theater is, a dedicated room for watching a movie and nothing more; perhaps this is just the beginning stage for their HT and a severe case of upgraditis will set in.

At least the seats look comfy.

It's not like I can really make fun of anyone at this point. My current HT room is just a living room where I have my gear. My new space still won't be dedicated strictly to home theater, but I sure hope I can have fewer compromises and have it look nicer.

Keep in mind that the people currently living there are in their upper 70's. I'm surprised that they didn't need a larger screen and something besides in-ceiling speakers so that they could actually see and hear the movies...

Where's the beef?
