I don't think this is really threadjacking, but a related question. First of all, I was somewhat confused about which is more effective, 12x12 squares or 17x17 triangles? I guess the 17x17 seems intuitively to me like it would be better, but I'm learning that I shouldn't just trust my instincts with acoustics
The second question I have is related to my own setup. I currently have a 4 inch thick 2'x4' panel straddling the corner. Would it be better to make this into a chunk absorber or not? Obviously with a chunk absorber (using the same material) I'm only going to be going up the wall 32" as opposed to the 48" I'm currently covering. What's the tradeoff, and is one preferable in different situations? I'm just trying to figure out the most effective approach. Thanks!
