Theater above basement

**pwest** · **06-28-09, 12:56 PM**

I'm converting my living room into a dedicated home theater. The room is 18' x 13.5' and is directly above an unfinished basement, and has a wood floor which is the ceiling for the basement. I plan on carpeting the floor and doing the usual acoustic treatments, but I was wondering about the subs. Should I build something like ASC's subtraps, to decouple them from the floor and also to help with the vertical room mode?

Sounds great. Are you asking with respect to sound staying in the room or regarding the quality of the sound remaining within the room?

All I'm concerned about is obtaining the best possible sound in the room. I live in the country and I'm single, so sound escaping isn't a problem. I was thinking that running a pair of THX Ultra subs in a room constructed this way might equate to a a whole lot of movin and shakein goin on.

I wonder what sort of construction might help you in that respect. A structure built with a resonance point of 50Hz might be a fun ride.

That would start a little structural roller coaster starting at 65Hz down to 35Hz.

I think the carpet will definitley help and it might be enough. I would set them up and run the system before getting too worried. If you find that after a sound test you need to do something else you could use something like a subdude by auralex.http://www.google.com/aclk?sa=l&ai=C...s/SUBDUDE.html

The SubDude might be just the ticket, and I am considering that as an option. I read a test report on the ASC subtrap that said that it was very useful, when you had wooden flooring over an open space ( sounds familiar ). The reviewer stated that this flooring arrangement is quite suseptible to flexing, vibration transmission, and self noise ( whatever that means ). Also that it would help with the vertical axial mode, usually at 70 Hz with an 8' ceiling. I'm usually not a DIY kind of guy, but it doesn't appear that it would be to hard to build a combo isolation platform and bass trap.

Carpet may help, but a good flooring like wood would look better as long as its installed properly.
