Hi,
Your needs are pretty specialized. I would gather few of us have experience with a 40x30x tall as a barn ceiling room. I recommend using the systems gallery part of Agon and reaching out to the other members with such a large room. A quick glance of these systems show speakers like VMPS, Apogee, Focal, etc. They might at least share their experiences with you. Filling up a barn-type structure sounds pretty daunting, just guessing, you will need at min two of your velodyne subs. At the Bay Area Audio Show this summer, Legacy (think it was their Whispers) filled up a good size ball room with their speakers. It sounded pretty good to me. Best of luck and enjoy the barn house, I always thought the designs can be very rustic cool.
