1) Would it be a good idea to make the mid/high absorbers at first reflection points as 4" thick plain OC703 panels as it would increase the low frequency absorption. Or for the fact that these panels are in the walls (as opposed to corners) they will not be effective as bass traps.
2) Could someone also explain me why the lower frequency sounds gather up at corners?
