Super Chunks with a twist

Posted by johnvb on December 12, 2010 at 09:04:08

Wanted to get the opinions of the folks here of an idea I have for some bass traps. As you can see above, I've already built some flat 2'x7'x6" bass traps using OC703, also eight 2'x4'x4" wall panels for first reflections.

I put these together while I was running mono pole speakers, in a 11/6 x 15/6 x 8 room, but they are still unfinished sitting as you see them, in the attic. The room has a slight 45-degree cut at the wall/ceiling transition, thus the 7' trap height, instead of a full 8'.

I've since changed to Magnepan MMGs, and want to do something different. The 25-1/2" wide, 6" deep bass traps would have been big for the room to begin with, and would of encroach into the swing area of doors on the front and side walls.

So I thinking of going the "super chunk" route, but with a smaller 16" x 16" back side length, and a rounded front facing side, with some sort of reflective material added, similar to how ASC adds reflectiveness to their tube traps. Think of a pie cut in quarter slices. Will I get close to the same bass trapping performance as using the above panels (which are close to the size of the Magnepan MG20.1 models!). And what can I stick onto the 703 to add reflectiveness, that can bend along the curve, if I go that route?
