Hi All,
I have the opportunity to build out a new listening room and have some questions for the experts.
This will be a conversion of an existing garage space and will likely be used for 3 - 4 years (at which point the garage will be torn down and a new addition to the house (with a permanent listening space) will be built. Given this fact I'm looking to balance the cost of this build-out against its longevity.
The space:
In order to properly finish the room I will need to build 4 interior walls inside the existing space. There are reasons for this that aren't worth going into here. The maximum size of the interior space is 16.75' X 18.25'. The ceiling can be flat at 8' or be a tray up to 9.5' (sloped up around the perimeter to a flat ceiling at 9.5').
Based on the calculations that I've done I'm zeroing in on a finished dimension of 15' x 18.25' x 9.5' (tray ceiling). This seems to pass all of the major criteria (Bolt, Bonello, etc), has a volume close to 2500cuft, and still provides a good sized space for the arrangement of equipment and furniture.
Have I missed something here? Is there a problem with these dimensions that I'm not seeing?
Trapping:
Aside from all of the usual bass trapping methods (corner traps, panel traps, etc) I'm wondering what other methods can be employed. Since the room will be built narrower than the space available I will have wall cavities on either side of the room that are approximately 15" deep. Is it possible to use these cavities as massive broadband bass traps without introducing other problems? My concerns in this approach are screwing up the room dimensions that the bass frequencies see as well as increased sound transmission to the outside.
Am I better off just building a tight inner room and treating inside that room?
