Let's not forget the room modes that exist in the standard American ranch-style bedroom and the manner in which they exhibit themselves in a bedroom studio production.
A typical 14'x9'x7.5' bedroom is going to have significant modes at 60Hz, 80Hz and 120Hz, approx. If the interaction is destructive (i.e. canceling in nature) you're closet engineer is going to be reaching for those bass knobs as a matter of habit.
I always ask for room measurements of spaces used in home recordings. It's nice to know what not to expect.
