Use recessed wall for sub or seal it up?
I'm about to have my water heater moved which leaves me with a question of what to do with the space. I'm inclined to just put a wall up. However I remember reading a pretty long thread, probably a decade ago, discussing the idea of putting a sub inside a recessed area of the wall. I don't recall the conclusion, but I think it was from the audio theory forum so there was a lot of...theory/pros/cons.
I've got a down firing sub. Would it be worth sealing up the top half and keeping the lower half for a sub to sit in? If I had to guess, the answer is "don't do that!", but I just wanted to double check before close it up.
Thanks for the input,
