I'm a DIY speaker builder, and after years of listening to commercial monkey-coffin boxes, have been fabricating a series of bipole and rear mouth back loaded horn enclosures. It's not likely I could ever again settle for a simple direct firing system.
Circumstances have recently required I migrate my audio system ( 2 channel only) to a former basement bedroom. The previous room was much larger and while not without some minor issues (due mostly to concession to "wife acceptance factor" ), it was quite tolerable.
Approximate dimensions of L-shaped room:
8'3"wide x 23' long, 7'6" to suspended ceiling, with a unfortunate structural beam/ventilation soffit (8"x20") across the width of the room.
Two exterior walls are half height concrete, 2"x6" stud walls with raw 'glass batts/ vapor barrier / 1" styro / 1/2" gyproc. Interior walls are single layer 2"x4" stud framed/ raw 'glass batts/ 1/2" "donnaconna" fibreboard/ 1/2" gyproc.
It became immediately apparent that rear and side-wall mid/HF absorbsion/diffraction is required, for which the designs and implementation examples are easily understandable. My main question is without completely reconstructing the room, how to implement wideband treatment on the rear / side walls.
All of the loudspeakers in my current and future planned collection are either fullrange bipoles, rear loaded horns or open baffles. The compact horn enclosures in particular are designed specifically to use the room corners to complete the final flare / mouth of shortened horn.
something like this:
* pardon my computer skills, I couldn't get it to properly display in post.My initial intuition is that (diagonal) corner mounted bass traps that seem to be a standard technique would seriously limit if not completely destroy the room's contribution to the LF extension of these designs.
Any comments or observations appreciated.
