I tried this one room at a time.
My 12’ x 16’ foot office space most closely resembles figure 2. Harbeth SHL5+40s were initially firing down the long wall, then the short wall. I liked it the best set up as indicated on the decware site.
My 15’ x 15’ room (I know, squares are really bad) is set up in a similar manner as my office (but with a little asymmetry with the room corner they span). Both a new pair of Magnepan LRSs and an old pair of B&W 801 Matrix S2s sounded much better after the new vs traditional placement. Best improvement of all rooms.
My 10’ x 15’ spare bedroom is also now set up with corner asymmetry placement.
Only tried a new (ish) pair of LS50s and an old pair of Rogers LS3/5As in there. Since these are so easy to move around, I tried the long wall/short wall thing first before going with the diagonal placement.
