I had thought about it but was beyond my expertise. Anything I should do to give me the flexibility down the road?
I don't know what you are planning for wall treatments, but for my particular panel design, it worked out better to have the stage and riser at the same height. I see you are planning a slightly taller stage, so that may become something you need to address depending on your wall treatments.
Also, my riser is similar to yours, except I went with 2x12x instead of 2x10s. When constructing a step in front of the riser (splitting the overall height of the riser in half), I didn't have a lot of wiggle room on the face of the riser or the step to fit a fairly small step light. With your 2x10 riser, your front step will be even shorter, leaving even less room for a step light. Not sure if that's a concern or not.
Another good thought. I will have to lay that out tonight. As I mentioned above I don't have any flexibility in the riser height.
If you can spare the height and the extra $$ to decouple the floor, you could skip the Serenity mat and use this 1" decoupling / isolation product from Kinetics Noise Control: http://www.kineticsnoise.com/arch/rim.html. It works extremely well and has a built-in vapor barrier. Just roll in out and start installing the two layers of T&G ply (or OSB) with GG in between. Two layers of 5/8" would be more than sufficient, but I like your thinking with the 3/4" sheet material if you can swing it.
Interesting product. The serenity map is already in my garage ready to go.
Squeaks typically come from movement against a nail within its hole in the wood. If you're not decoupling with Serenity mat (or other product) and concerned about squeaking, then a dab of construction adhesive will do the trick. I've not used roofing felt, mat or adhesive in the past and have not had any problems, but YMMV.
If you don't feel like making the extra trip and just want to get all your material from the riser and stage aisle at HD, I don't think you'll have a problem spacing the joists at 16" o.c., especially if the joists are the same size as the perimeter and run all the way to the floor. Personally, I don't think it's worth trimming insulation for this type of application. Space 'em at 16", stuff it, and call it a day.
I don't recall anymore, but I used it in 2004 for my last theater. Not to hijack this thread, but here's a couple of pics of the install FWIW. The double layers of ply floating on the pads with the Green Glue between layers was rock solid and really prevented sound transmission into the adjacent areas. In fact, it was difficult to ever hear anything outside the theater, regardless of volume. I used a rate of three 28 oz. tubes per 4x8 sheet for the "ultimate". Unfortunately this was in the days before the newer formulation and the speed loader, so it was quite a lot of tubes!
The "money shot" for you, Ted!
I can't take credit for the drywall. I was smart enough to know my limitations. I did all of the drywall in my joist muffler but not to the finish level of a professional. I have a TON of respect for those who have tackled the Sheetrock themselves!
I came home to find the joists for the riser done but they did 16"OC and not 12" OC as was specified. Spaceman is correct that it will be a snap to get the insulation in there with 16" OC. So what does everybody else say....with a top of 2 layers of 3/4" OSB is 16" OC plenty for a 9' x 13' riser? They are coming in the am to finish up so let me know if you have any thoughts.
We got another check mark today. The frame of the stage is done and I am VERY happy with it.
Now I need to pull some conduit and electrical to their final locations in the stage and riser. I already have power and conduits stubbed to the back of the stage and riser. So I have a couple of items that I need some help on:
1) STAGE: I am planning on keeping the power and low voltage boxes behind the screen on the wall and not in the stage. Where should I put the boxes and what have you guys found helpful to have in front of the screen wall? I don't think I need power. There will be outlets in both of the side columns that are a couple of feet away. Is one box for the low voltage conduit running to the rack enough? Should I put it on the front part of the stage facing the audience or on the stage floor facing up?
2) RISER: I will have (3) floor outlets for the rear seats and I will have (3) outlets in the front portion of the riser for the front row seats. I have a conduit for low voltage that runs to the rack. Should it go between the 1st and 2nd row or in the face of the riser behind the 1st row of seats?
I also have been trying to find a recessed box to put the power supplies for the chairs in but have not had any luck.
3) STEP LIGHTS:
Spaceman was correct. My space for the step lights got small in a hurry. I have enough room to mount a 3x5 box in the face of the riser above the first step but not in the step face. It is only 3" tall. I could frame a pocket for the box? Would a light for the step only be sufficient or do I need a light for the step and the floor?
This is the light I was looking at. Its 3" x 5". Would I be better off with rope lights?

Never heard of that term before........from your illustration, that's what I was referring to as blocking. Learned something new.....
I worked most of Sunday and tonight and got the low voltage conduit and the romex for the seat plugs in the riser. I also added some bracket on each side of the joists to firm them up a bit.
I decided not to run anything in the stage. I will make a hidden panel in the false wall for some low voltage (USB for xbox etc)
I had a little more room in the step that I thought. I thought it would be tough but I pulled the face off and moved the center support over a bit. It made it much easier to cut the box with the face pulled off.
I will try and get insulation done by the weekend and then get the tops on the stage and riser. I am starting to think about the soffits and trim. I also need to make some final decisions on equipment. So be on the lookout because I am going to need some help here.
OK gang I would not let myself think (to much) about product until I was sheetrocked and had the stage and riser done. So now its time to talk some product! Please let me know what you think about my selections below.
The big change will have to be the PJ. The LS-10i has been discontinued, Bummer! Runco has reduced the price of the LS-12d by 3K so that could be an option. The DP Highlite Cine 260 is very close to the LS-10i. Also some of the newer DLP/LED have gotten bright enough to work (Sim2 M150 or DP 1000 LED). These LED's intrigue me....3 chip color, single chip convergence, DLP pop, no RBE, no bulbs, less loss of brightness & instant on. What's the downside (besides cost)?
My setup will be a throw of 165" to a 120" wide 2.37 AT screen (Approx .8 gain)
