Looking for best tone match ATMOS in ceiling speakers to go with Polk RTiA speakers

[phillihp23]

Anyone have a suggestion, or experience with ATMOS in ceiling speakers which would be a close tone match too Polk RTiA speakers?
Also, my ceiling is vaulted and like this /\....not that steep though.

Ok...well I guess I found the matching in-ceiling speakers for the RTiA series, 70-RT. So the real question is the audio effect of installing in a angled ceiling?
