Hey guys. We moved into the new house in August. Had the new baby last month and now I finally get to spend some time getting my new theater up and running.\n\nThe plan:\n\nKeep my current Mitsubishi HC4000 1080P DLP projector until I get either a JVC 4K or a somewhat moderately priced 4K DLP unit comes out.\n\n \n\n120" DIY Spandex AT screen. Had one in the old house, but it was my first try and the plans I got weren't the best. Plus it was a grey screen with black backing. Going with white and black backing to brighten things up again and to prepare for a new projector.\n\n7.4.4 Atmos setup. My current receiver is an Onkyo TX-NR809. While it is a decent receiver, it has it's issues. It does have Audyssey MultiEQ XT which does a pretty good job, but I want XT32 and Sub EQ since I will have a sub in each corner of the room.\n\n \n\nCurrent contenders for new receivers are Denon X6300 and the X4300 if I want to use an external amp to drive two of the Atmos speakers...I don't.\n\nCrown XLS1500 to drive the 4 subs. Great amp.\n\nSubs are 2x DIY Infinity 12" 1260w and 2x 1262w each in their own ~ 2 cu ft box. Boxes will be finished in satin black.\n\n \n\nFront three speakers are Pioneer SP-FS52 Andrew Jones towers. Love these for the price\/performance ratio. Great speakers for the money.\n\n \n\nSide and surround will be old Kenwood HTIB speakers I got from my parents. I know. You don't have to say it. They work until I get matching Pioneer bookshelves or something else.\n\n \n\nAtmos speakers are TBD. Can't decide if I want to cut 6-8" holes in my ceiling or not. I don't.\n\nMy only source will be my trusty HTPC that will use SageTV for all TV viewing and Plex to serve up my movie collection (see picture above. It is under the Onkyo receiver). I'm toying with the idea of getting an additional Nvidia Shield TV that will replace the HTPC due to it having all the streaming services and it supports all the new HDR, Atmos, DTS:X and the like. We'll see how the HTPC does it's job first.\n\nThe room itself is 16'Wx15'Dx8'H. Kind of an odd shape being wider than deep, but it allows me to have a very wide space for lots of seating. Considering two 4 person home theater style seats to replace my current couch\/love seat combo. I'll be about 9' from the screen which should be fine. Any closer and I'd have to downsize my screen.\n\nThe room is pretty much a storage room now so I get to find new homes for all the crap that's in there, but it won't be too bad.\n\n \n \n\nThere are 6 can lights in the ceiling and an air intake and vent. Placement of Atmos speakers will be at the advice of everyone here. My brother works as an installer for Magnolia, but I'm not sure how much they've actually taught him.\n\n \n \n\n \n\nAs you can see from the above picture there is the intake pretty much right between the left side and left back speaker on the ceiling. I think Atmos speaker placement will have me put it enough away from it that it will work, but I'll have to measure and make sure.\n\nYou can also see that the guy that did the prewire was...special. The lower plates are from his first try. I had him wire again because he assumed I was going to have all my equipment in the front of the theater. He was wrong. It goes on the outside of the room.\n\n \n\nAbove is the correct placement for the 7 channel pre-wire. I guess he didn't realize that labeling the wires is a pretty standard thing. Glad I paid them for the prewire. They wouldn't do more. For some reason. I did have them put two dedicated 20A circuits and cat6\/RG6 in place. This is outside the theater in the Game Room. Good location.\n\n \n\nI told him to just have the front three channels come out of the same hole. No labels again. Thanks crappy wire puller guy. I have a toner so I got them all identified, but still.\n\nPretty much it for now. I'll update the thread as I progress.\n\nAny suggestions on Projector, speakers, receiver and anything else are always welcome. Sorry for the bad PQ. My phone is getting old.
