I guess my question is this: If you take out your feelings about AF, he is presenting a solution that is backed up by the numbers. Mathematically, you would want to know how much pressure you have and at each frequency. Then you would want to apply the solution that is designed to fix the issues (unwanted high pressure frequencies.)
If there is another solution out there (corner bass traps) that can also be used, where is the objective data and room testing process that dictates proper performance in mitigating the unwanted frequencies?
