a question about basement HT ceiling
I am moving in a couple weeks to a 35 year old 2-storey home. I am putting my HT in one part of the basement (12x20). I am putting a door up (with a lock...to keep the little ones out when unsupervised). The basement is "mostly" finished. The ceiling however, is open. When we move in, I am ripping out the carpets upstairs, and laying hardwood. Downstairs is where I am perplexed.
I want it to sound great in the HT, and I want little sound to travel to the second storey to disturb or wake my family. I have read about a room within a room etc, but I think I have decided on stuffing the joists with insulation and screwing up drywall. I guess I would then seal the seams with caulking. Now this is where I am stuck.
A) Do I put a resilient channel and drywall again...and then hire someone to tape, sand and finish?
B) Do I drop 6 inches and put in a suspended ceiling?
Although technically capable of finishing the ceiling, I am going to be too busy these next months to do the finishing within a reasonable timeframe. If I get someone to do it professionally, how long would finishing a 240 sq. ft. room take? Would I need to remove everything out of the room to do the work? Can I reduce sound transmission with the insulated drywall & suspended combo?
At the end of the day, I want something that will keep the sound in the basement...that looks good...is a quick solution...and disrupts the HT (and rest of the house) the least.
Thanks.

If you want a sealed room, you're gonna need a solid ceiling like the resiliant channel + drywall idea, a drop ceiling won't do much for isolation.
Then you'll want to deal with in-room acoustics as well, so if you have the headroom to build a good ceiling structure, I'd do it. I did not (low ceilings), so It's a simple drywall ceiling.

With my basement HT room I stuffed my joist with insulation, used resilient channel and double drywall (hang drywall left to right, tape mud, install 2nd layer of drywall front to back, drywall glue/adhesive caulk, tape and mud.
The only thing you can hear on my first floor is bass, but only when I am playing at very high levels (reference or above).
It should not take more than 3 to 4 days for a contractor to drywall, mud and finish your room. If you go with a skim coat or texture coat it will take even less time.

Rob,
My ceiling is also sheetrock (1 layer 5/8")no Resilient Channel, with fiberglass insulation (R13)between the joists. When the volume is cranked up I can only hear the bass slightly upstairs. I have carpet in my living room which is directly above so I'm not sure what your proposed hardwood installation will add or subtract to your equation.
You also may want to consider any HVAC ducting that you may have as this can be a great source of sound transmission from your theater to the upstairs rooms.
It's also easier to remove everything possible from the room before the project begins than it is to clean it afterwards as this is a dirty/dusty job.

Its a metal channel that seperates the drywall from the lumber. Check this out.

Just one thing to keep in mind if you do go with a drywall ceiling in your basement. Will you ever, ever, need access to anything up above in the floor joist such as plumbing or HVAC?
If your answer is "no" to that question and you do go with a drywall ceiling, then don't forget now is a good time to install speaker wires for your surrounds. Even xtra wire for future rear channels.
