Surround speaker suggestions

[Rockoutwurcokout]

I recently purchased a set of mirage om7’s with the mirage omc2 center channel to match. The matching surround speakers are the omr2’s but the recommend placement is wall mounting. My room is 25 x 25  engulfed in glass with cathedral ceilings also glass on the back. What speakers should I go with to match the setup. I could mount those really high or put my surrounds on a speaker stand. Thank you guys in advance for your help.

I have found that staying with same brand speaker ( To keep away from tonal discrepancies) . I am sure mirage has some form of rear channel speakers. Just MHO. And I would put them at the same height as the fronts.
