I'm building a dedicated HT room and I was thinking of using the empty space under the stairs to the basement and build an alcove for the subwoofer. I have an EP350 v2. Here's the pic of the space...



I would remove one of the studs and reframe an opening, then soundproof the back to ensure sound is kept inside the room.

Would that make sense? The goal is to maximize space in the 13 x16 room and I don't know where to put the sub.
