I have a decently treated room (basement) and I can play pretty flat to 15hz in my room with my 4 subs and, even with it cranked, it is a non-issue with neighbors. The bedrooms are two floors above, and even at night when if I crank up a movie I have never woken any of my three kids up. Point being, you may be overanalyzing this unless you are talking about shared walls or having something like 10+ 18" subs in your house.
Sorry, I missed this post the other day. I often check/post on mobile, and sometimes miss a post.
Very good chance i'm overanalyzing it, as I tend to do that. Probably one of the reasons I love forums.
The Home Theater is being built above the garage (garage below is 2x6 construction with 5.5" of foam in all walls), in my new home build. Two of the home theater walls are 2x6 walls, that will have brick on the outside, 3" of closed cell foam on the inside, and then R-13 batt insulation, with the double drywall/green glue/clip & channel inside of that. One wall (same treatment, minus closed cell foam and brick is common to a bar/lobby area outside the home theater. The last wall (2x4 construction with R-13 batt insulation & same interior wall treatment of course) opens onto an attic space, which is about 6 feet wide (sloped ceiling) and the roof area will have 9" of open cell foam, the short wall 5.5" of closed cell foam, and then brick on the outside. The roof deck above the theater will have 9" of open cell foam (not sure how much open cell actually helps abate noise, especially LF).
The room, designed and build by Erskine Group, will have full acoustical isolation treatment.
The two nearest neighbors (one across the street and the other next door, uphill a bit) are roughly 130' from their closest wall to the closest wall of the home theater.

And that would be just plain stupid.
Some of these bass heads will rue the day they chased the "nth degree" of bass response and reference levels. They'll be practically deaf come retirement age. Home theater rooms are not large commercial auditoriums.
I opted to have the Erskine Group build the theater, to make sure it didn't get mucked up (I have great contractors that actually built a treated/isolated home theater in the house two before mine, but it was still only their first time) and so I could get moved into the house sooner.
So, hopefully, I won't have any issues with the construction being mucked up, since Erskine designed it, and Steve and his crew that build pretty much all of the Erskine theaters will be doing the theater as turnkey (minus equipment).
