That is correct, I am having to 'stealth' mount the sub in an adjacent closet an have it face into the listening room with the face of the speaker flush with the listening room wall. I was lookiing at some of the suggestions of subs you have made for folks with similarly large volume rooms and thought one of the box mounted kits might work. I guess it is fortunate that I can have it protrude in the adjacent closet and not be confinded to the space within the wall. If I framed around it in the wall, do you think this would be a viable plan? A paintable speaker grill would be a bonus too. Thoughts?
