ok I'm not sure I agree on the drywall before riser thing, er rather I'm not sure it matters to me and here's why...
First and foremost - We are not loud speaker people. As I said before, I don't think we've ever cracked 90db and that's when the theater was COMPLETELY open to the rest of the basement. Now that it's enclosed I can't see us going even that high.
Second if you look at where the riser is adjacent too, none of those areas need sound protection. (Yes I realize that I'm in experienced with sound proofing and maybe even incorrect, but I'm also balancing cost and functionality here...) - the riser is bordered by 1) the stairwell and gym, 2) my unfinished office (also protected by 2x6 split stud wall) and 3) the insulated concrete wall to the outside. I'm not really concerned about _direct_ sound going in any of those directions and I don't "think" we will be generating enough energy to worry about indirect sound waves having much of an impact escaping the theater.
Third, I'm trying to wrap my head around how the riser filled with insulation is going to be any different than a the riser with insulation coupled to drywall.
Finally, my contractor is sort of doing me a favor. He had initially bid on this project thinking he was going to do the entire basement and then I backed down to just doing the theater so I'm trying not to be "ticky tacky" with him if I can avoid it or at least not without good reason.
If I'm way off base and this is really critical and I'm missing it, please let me know.
