Two of the rooms on the long sides will be unfinished and I will only be the ones those rooms for any length of time so the sound there shouldn't be an issue. I am going to soundproof the ceiling to mostly keep from hearing people walk around upstairs. What are your thoughts? The room is framed and one side has drywall, but not totally complete yet. I am trying to save money.
Two sides are the concrete foundation of the house. The 3rd is the mechanical room with the HVAC, Hot Water Heater, etc. The last side is part of the game room, but above is where I'd have an issue. My master is directly above the theater.
Unfortunately, I'm not really qualified, nor comfortable to answer your question. This is my first theater and to be honest, I don't even know if what I did works yet.
I will say that it is expensive. I'm probably $5,000+ on soundproofing when you consider the additional cost of the drywall. To give you an idea, the rest of the basement (~1600sq ft) was about $4,000 of the drywall quote, the theater was $3,600 and it's only ~260sqft. Add the price of the clips, channel and the $300/bucket of green glue and it gets expensive quick.
The flip side is that if you don't do anything, you won't know how bad it is until it's too late. I have read that soundproofing is pretty much all or nothing. You'd want someone like Big or Ted to answer your question.....Sorry I can't be of more help.

I love it. It's a great game for the price. The one thing you want to be aware of are the ramps. They are unavailable. No one sells them, so if they are damaged, broken, etc, you won't be able to get replacements. Depending on the condition, you should be able to get it anywhere between $2k - 3K. $2k would be for one that needs torn down, cleaned up and rebuilt (pops, flippers, etc). $3k would be for one in excellent condition, nothing broken and most likely with an LED swap.
Let me know if you want any help with pricing or checking out pictures for you.

Would you mind describing how you hung your atmos boxes? Looks like you attached them on the bottom side of your channel but that would leave an air gap between the speaker face and the ceiling drywall.
Sure. It was tricky to get them up correctly, but here is what I did. Keep in mind, that with two layers of 5/8" drywall sandwiching OSB and green glue, these buggers get heavy. I built the boxes and then ripped some 2x4's for arms. Then I went to harbor freight and bought two Cargo Bars
(make sure you print a coupon). Next, use the cargo bars to put the box in the ceiling and line the face of the box up with the channel. You want to the box face, to be flush with the bottom of the channel. Once you do that and have it in place, hold the arms on the side of the box so that when attached, they will hold the box exactly where you have it in the ceiling.
Then I marked the side of the box, pulled them down and attached the arms. Then it's just a single drywall screw through the channel into each side of both arms. When you're done, the face of the box will be flush with the bottom of the channel which is technically the back of the drywall. Add a big old bead of acoustical sealant on the face of the box and you've created a sealed box in the ceiling.
All you have to do is cut the hole in the drywall and put your speaker in. The box doesn't hold the speaker, it just provides a cavity to contain the sound.
I'm not sure if these pictures will help or not. Oh, and if you have someone come in to drywall, make sure they know not to cut out the box. They are just supposed to drywall right over it and you cut out the drywall later depending on the size of your speaker.
