Hi Ethan,
I am starting a bass trap project, and it looks like you have a lot of experience in this field.
I have a dip in the frequency response around 140 Hz. Not really bothersome, but knowing that it is there, and enjoying small projects like this make me explore my options. The frequency corresponds to the wavelength of a reflection from the wall behind the speaker. The front of the speaker is about 2' away from the wall, so the reflection would be 1/2 wavelength, 4' - 140 Hz.
Since my room is over the garage, I can replace the sheetrock walls behind it, if I want to, up to a height of 40", then the ceiling slope starts anyway. I could also build a membrane in front of the wall studs. Behind it is insulation, and the attic, no problems there.
What would you recommend, as far as the membrane is concerned?
