After reading other posts, room mode simulations here, and flow resistivity estimate here, my assumptions are as follows .
1. Corner bass traps and the idea that "bass builds in the corners" isn't all that accurate. Maybe it's 2 walls next to eachother so one square bass trap partially covers 2 walls at one time. But it isn't better than a full wall "bass trap."
2. Thicker insulation with less density is best for bass trapping. Therefore pink fluffy insulation is better for thicker traps compared to mineral wool.
3. For my space I can utilize 8"-16" on front wall and same on the back wall. I calculate that 8" of insulation with an 8" air gap does similar bass attenuation compared to 16" of insulation (OC pink fluffy insulation with flow resistivity of around 6k-8k).
Therefore, my conclusion is building width/height walls out of insulation for the purpose of bass attenuation is best and I'm better off using OC pink fluffy with an air gap to be most cost effective and best performance within my allowed space. Of course, measure results and make adjustments for my space after measuring.
Am I on the right track?
(Possible follow up question. Would it be better to have both front and back wall 16" bass trapping, or only one wall 32" bass trapping?)
