Oh andI cant see where your missing the 2 subs either
2 more going in the back of the room. Short and squatty but the same internal volume, same 18" drivers, and same power to them as the others. Also not pictured is the 4 Atmos speakers and 4 surround speakers, each are DIYSG Volt 10lx's, 10" midbass drivers with coaxially mounted internal waveguides and compression drivers for the highs. All the speakers were built in my shop, with only the drivers and SEOS waveguides purchased (all DIYSoundGroup kits). Subs are Dayton UM18-22's from Parts Express, and each one takes about 2.5 sheets of 3/4" MDF and weigh close to 300 lbs each.
Aside from hiring out the mudding and taping, I have done 100% of this myself, from electrical and HVAC, to low volt wiring, to framing and drywall (2 layers of 5/8" drywall with green glue in between, mounted on hat channel and clips for sound proofing), riser and stage construction, all columns and trim work, paint, speaker building, acoustic design and treatments, etc. It has been my life every evening and every weekend since Christmas and I am about 700 hours into it with almost 100 hours of work left. I watched the first movie in there tonight, and although we were sitting on lawn chairs, I was pretty chuffed. I will post some pics when done in a few weeks, the room is looking really good but I still have 80 cloth panels to build and a few other details, like hanging the 200lb door and finishing the air circulation system for the projector housing.
