well i think the nice thing about andreas leading the way on the rotary build is that he does all the hard engineering work. the rest of us can just order parts from machine shops spec'd out based on his experiments and assemble.
well YOU have ME converting mine. I am thinking about cutting my towers down, putting 2 manifolds between my spare room and HT room, and my door will be just like your access panel. I plan on testing with the door sealed shut, sealed IB, and open, 11Hz tune with the 23" x 88" x 4" door way as the port.

Optimal viewing distances, x = screen height
Are these correct, an the guidelines you're using?
