The 511/808 vc lines up w/515 vc axially
In the 811/808 application the bug screen and 515 screen line-up axially also.
Question: is the compression assy output plane (assuming the screens are in the intfc plane)
a more correct alignment feature (from a listening standpoint)
OR is the VC align. still "king of the hill"
