Well, I have a few questions/ideas. First off, I'm a bit limited in space in my future home cinema (4mx3m room), so I was wondering, to save space, could I mount a pair of subs in sealed enclosures in the ceiling (see attached pictures)? These pictures are to scale, but the enclosures aren't final size (will obviously be decided if/when I buy drivers), they're just there to get the idea across. The enclosures would be made of 2 pieces of 1/2" MDF laminated together, glued and screwed together, then probably bolted to the ceiling joists either side (it's the loft above the room, I though about IB subs, but unfortunately the walls at either end of the house have gaps, so sound would travel right into my neighbours lofts. And also, coupling those with a pair of these installed in the sofa. Ideas? Opinions? Crits? Or would I be better just nipping this idea in the bud and going for something along the lines of an XLS200?
