Congratulations on the latest design.

1) Is it more beneficial to construct a straight wall (of drywall) perpendicular from side to side, making the corner bass trap with 6" of 3pcf fiberglass and supporting wood for the soffit,
or
Is it better to build the angle with framed drywall, then cover the surface with the 6" of fiberglass?

It six of one and half dozen of the other. Personally, I would angle the wall so that soffit mounted speakers are at the 30° mounting angle. Nothing hard and fast on that.

2) Can you recommend an RT60 time to shoot for in my ongoing calculations? Or is this a crazy question?
350 ms based on your dimensions and the EBU/ITU standard.


I have a big problem with the ceiling. The material at 15' will be acousitically transparent at low frequencies. The room modes will develop to the 30' dimension. Also, I have no idea how the absorbent material will actually absorb being basically suspended in free space, vertically. Jay, any ideas?
