Preventing Bass from reaching other rooms

Hey all! Was just trying to see what's everybody's take on this one:

Last winter I went to a restaurant right about friday night, the kind that has a sit and eat area and a bar area next to each other separated by only a glass wall and some booths...

Now don't get me wrong, I love BASS but when you are trying to talk to your spouse you need full attention or either: She will get mad at you / You don't get your point across.

Regardless, bass was overbearing the already loud friday night scene, I could tell the room resonances were playing their part plus a poorly designed subwoofer enclosure since I could tell 40Hz was almost OMNI-present :rolleyesno:

Bar sub was mounted on the ceiling and I could have a clear site of it from the restaurant area, I would say that's the first problem and in a commercial environment I guess if you go to fellows like GIK they would probably have a fix for it, but what about a home?

If bass is nice and properly felt in the living room, what happens when everybody is having a nice conversation in the kitchen, on an open concept floor space?

THANKS!!!
