Hi Steve:
I have a 7.1 speaker setup and just recently moved my 534’S to the sidewalls.
I had a pair of 422’S near that location which I did not really like because the sound was too directional. The 534’S provide a broader sound, not directional at all and great for movies. I am experimenting between Bi & Dipole.
At first I used the 534’S as front main on speaker A with a pair of 532’S on speaker B.
Since I am waiting on my new 632’S to arrive to place at front speaker A, I made a shift in the position of the 534’S.
I have the 534’S mounted with the top placed at 49” and the center of the speakers mounted to the center of you’re ears in the audition area. I am really impressed with the sound they produce which is great for movies.
I would recommend the 534’S for surround since you have the option of bi-pole or di-pole.
Jack
