Im going the DIY route for acoustic room treatment and I want to start with bass traps.

I have the budget but I'm curious which, if any, of these bass trap methods have significantly better low end benefits than the other.

Bass trap styles:

1. (15" + 8' tall) square superchunk
2. (15"x15"x21" + 8' tall) triangle soffit bass trap
3. (6" thick + 8' tall) panel placed 45 degrees on the corner with an airgap.

   Thanks for any advice or insight on this topic I am obviously a newbie at this and I appreciate the help. (y)

   If needed:
   11'x11x'8' room.
   Using Roxul Safe n Sound.
   Not for mixing or anything too serious just a listening room.
