Although this has nothing to do with 8th Nerve products per se, I figure this is the only acoustics-related vendor here, so what the hey.
Let's say a guy had this window in his listening room and it had a sill that was unusually deep on account of it being in the basement. Now if one were to stretch that 3M plastic window insulation over it in order to keep out the winter drafts would the resulting drum-like cavity serve as a helmholtz resonator of sorts and trap certain bass frequencies or would it act as a resonator\amplifier of ugly bass booms? Normally I do put this stuff on the windows in winter but it never occured to me that the tight membrane might have some sort of acoustic effect. Any theories?
