It depends on the height of the ceiling. But for a standard 8 ft ceiling, the rear surrounds should be at least 3 ft behind the listening area. Wherever they are, they should point over the listener's heads, and towards the middle of the room.

For side surrounds, they should be between a few inches to 2 feet behind the listening postion, and aimed at each other, perpendicular to the wall behind them, like this...

Can the 522D-SS be ceiling mounted using the Omnimount 20.0 Ceiling Mount (do they require 2 mounts for each speaker?)?

Can they be wall mounted using either the B-Tech BT77 Wall Mounts or the Omnimount 20.0 Wall Mount?

The room I plan to install the speakers in is pretty much a perfect square, with pre-installed wiring for the Front Speakers (522D-LR) in the wall.  I had planned to use the B-Tech BT77 Mounts for these.

The rear wiring comes out of the ceiling, but is close to the back wall, where the couch will go.  I was planning on going with the 522D-SS for the rear speakers.  Esthetically, I would like to use the same mounts all around, in which case I was considering the B-Tech BT77 and just mounting them near the ceiling (8 ft ceiling), assuming the 7 degree tilt will be adequate enough for a couch position against the same wall.

Any suggestions or information would be greatly appreciated.  I have been reading through the forums and every detail of information I can get my eyes onto on this site.  I am sold on Aperion because of the passion of these customer testimonials.  I work for a company with the same dedication to customer service and we have had the same fortunate success.

And of course, an Aperion 5.1 package with the 10" Intimus, the 522D-LR for the fronts (and maybe the rears depending on your responses), and the VAC (despite Brian's posts in praise of the 522D-C -- only because I never did hear anyone compare the VAC to the new 522D-C)

Thanks for your time in reading and responding,

Hi Anatol. The 522D-SS speakers can use the omnimount ceiling 20.0 or wall 20.0. You would use one of these mounts per speaker. The BT77 won't work with these speakers because of their width.

Hope that helps!

Thanks Ben,

Are the 522D-SS appropriate for Rear speakers in a 5.1 setup with the couch against the rear wall?  Or would I be better off with the 522D-LR?
