Ok heres what I am coming up with. The sub will be on the floor recessed into an in wall column with the front of the sub either flush with an opening in the column or even sticking out a few inches. I can play with that to see if it does help the sound. I figure i will use chipboard above and begind the the sub, green glue, drywall for finishing. I will insulate the entire inside of the column. Do you think I should use any sort of acoustical panel inside of the cabinet over the drywall?
