Looking to add RTi A1's to my home theater room as Front Height speakers. Need a solution to mount them. The mount must be able to adjust for angle down and in toward center of room. I really like my Polk 9.2 setup but I found Polk lacks mounting solutions for there speakers. Excited to see what the next level 11.2 will bring to my theater experience. I use Audyssey DSX to produce the sound on a Denon 4520.
