Absorbers at the reflection points

[pinhedgtr]

I built the bass traps in all the corners, but now I need to build the absorber panels at the first reflection points. My question is, what type of absorber do I need to build? Mid-high, high bass, or other? Thanks for your help!

You want as broadband as possible. 2-3" of 703 with a few inches of air gap should do the trick.

cool thanks I went ahead and followed Ethan's desing for a mid-high absorber. Now I just have to hang them.

Will the Roxul 3" stuff do a good job at HF absorption?

2" 703 with 1/4" poly batting on the face covered with burlap.

Depends on what kind of Roxul. If it's the 2.5-4lb it will work just fine. The 8lb can be a bit dense if you have a case where your reflection angles are real shallow.
