Typical framing would be 16" or 24" on center, with 14 1/2" or 22 1/2" between ceiling joists (or rafters). With "conventional framing" it is usually no big thing to "head out" for openings, and soffit and/or frieze vents plus ridge or near-ridge vents might substitute for gable vents, depending on specifics TBD. Shaking from ULF is another matter. I have seen a "demonstration" where a "sub-woofer" hopped around the floor despite a heavy sculpture atop it. In another, fairly recent thread I mentioned double-walled "theater" boxes. Those I referred to have a space between the walls, and they do "work" for Music. I have long had the dream of using this type of LF enclosure for my 30" drivers (I have cones and motors), if I ever actually build them. As for combining LF channels, as frequencies drop, it seems like all bets are off until one actually tries something. People have told me that an odd number is always better, but I have heard some pretty compelling "stereo" LF installations. Again, ULF is always "another matter".
