Bill,
Your partially right in the mention of the use of a manifold. The application though is to the ceiling and wall convergence in my sound room. Got rid of those horrendous sounding 90 degree angles and recontoured them with 33 degree angles which edges roll away into the flat of the ceiling and wall. Got that idea when I had a new header reheated and bent to clear the linkage of my old Lotus Europa twin cam. Tom
