If you're planning that fiberglass boards will be significantly effective at low bass frequencies, you'll need a lot more of them than you're probably thinking.
Dang!!
I am just getting my toe into this treatment area and was hoping a few panels in the corners and on some of the obvious points of reflection would make a small room act a bit larger, and even out my low frequency fear. As my room is not a uniform rectangle, most of the software for modes looks pretty useless for my room. I guess I need to get the REW software, the SPL meter, a mic, an external sound card (for laptop) and run some test tones. I assume I should still put absorbers at the first order reflections and diffusers at the rear? Right?
I clearly have just enough knowledge to frustrate the bajeezes out of me.
