Well I found my “sonic laser tape” measuring thingy. Really makes taking room measurements a breeze. Anyway, the room is a little better than my original plot. There are still issues obviously, but the modes don’t seem as bunched up and reinforcing as I feared. (I’ve posted the actual plot to the left.) Hopefully this will make it easier to deal with.
I’m still amazed at how costly it is to deal with this stuff properly. I am skeptical of most of the cheap glue/foam products you can find at places like Guitar Center. They may work fine as diffusors but, according to articles in publications like Sound on Sound, you need something with more density to act as absorbers, particularly at the low frequencies that are at the center of my issues.
