Question on decoupled ceiling for a new build
I've been lurking and reading as much as possible over the last few months.
I have a quick question and looking for some advice.
Here is a quick overview of what I have and just started doing.
14' x 26' 4" x 8' rectangular theater room in a few year old home. This area was a finish 14 x 22 x 8 media room area by the developer in the basement. Three of the walls are insulated and space a few inches off a pour foundation wall. I opened one 14' wall up to a max distance of 26' 4" for better seating. I will have two rows of three seats first row will be about 13' - 14' from the screen. Rear row about 20 - 21' on a riser. I have a HVAC business so I can get OC QuietR 1" FRK 475 and 2" 1400 along with duct liner at cost so I will be doing panels and bass traps in all four corners.
Seymour center stage xd 130" diagonal 2:35
JVC 4910(just got it from AVS)
Two UXL18 (Waiting on shipping)
Two mini Marty's 80% finished
Emovita XPA 5 , UPA 7 and a UMC1
I may need to use my current Mirage OM6's and OM-C2 for the front till I decide on the front speakers. Unless they can keep up. I was looking to possible do Triad Bronze dipole side surrounds in columns and there Bronze mono's for the rear. Unless there is a commercially lower cost option that is just as good. Or DIY 1099 for the front and the Volt 10's for surround. Any suggestions are welcome. I haven't decided on a budget on that end but of course cheaper is better.
I don't have plans on tearing the room completely apart and isolating everything with clips. I can except that the room will not be completely sound proof. But I did have to drop the ceiling to modify a duct run in a soffit to make it smaller and the original lighting won't work. So when I dropped the ceiling I noticed that none of the top plates on the three walls are touching the first floor joists ( maybe in 2 or three spots). The fourth wall still need to be built and were the others might be touching I could notch the plate a little. The only contact points are a nail or two every other floor joist.
So here is my question right now. Does anybody think that with just the contact points of the nails the walls are decoupled enough? If so it makes sense to now decouple the ceiling with clips. I would be willing to do the additional work if it is going to help.
I tried to at least get a photo, I hope it attaches correctly.
Thanks for any input.
