The extent of any sound mitigation is R13 fluffy in the walls and a double layer in the ceiling (one layer tight against the subfloor a 3in gap and another basically flush with the joists). There is a "solid" exterior door...solid foam. So far the sound is really not bad, the theater is under the master bedroom and part of the living room. With the sound at about 55-60 the door closed you can have a normal conversation in the adjoining rec room...you can hear the theater noise but nothing you have to shout over. The wife has even watched movies/shows upstairs at normal volume 10-11 on a older Samsung soundbar and other than occasional bass not really notice.
Phase II if it ever happens will be some robust soundproofing with 2 layers drywall, snot (as my aunt who does soundproofing/structure work), hat/channel, attention to outlet/box/recessed light openings and a better door.
Room dimensions are 18' 8" (screen wall to back wall) 12' 10" x 7' 8". Riser is 6in tall, pressure treated lumber laying flat with 2x4 and 3/4 TG.
