| I doubt if a "minichunk" would outperform a 2' wide panel that is at least 4" thick. Bass trapping is also about surface area and coverage area in the room. Though without seeing the 2 approaches tested (at the same time by the same facility) it's hard to tell.
Basically you reach a point of diminishing returns. 4" panels straddling the corner give about 80-90% of the performance of superchunks, at a much lower material cost. In general, you are better off using that material to cover all 12 corners of the room. If you want to superchunk all 12 corners, so much the better.
Spacing panels out from the wall gives increased overall absorption, and more absorption at the lowest frequencies. So theoretically, the thicker the material, and the further spacing from the wall, the better. But once you get 4" thick straddling a corner or 4" out from the wall, you are getting close to the top of that curve. |
