I currently have two in-ceiling speakers installed in my basement to the rear of my couch, which I intend to use for a home theatre. I was considering the Sonos Arc given its support for Dolby Atmos at a reasonable price. However, I was wondering if using the in-ceiling speakers in tandem with the Arc for surrounds would have an enhancing effect, negligible difference or an adverse impact. My worry is that the in-ceiling speakers may interfere with the up-firing speakers on the Arc… is this something that Trueplay will calibrate for? I am aware that the Dolby setup guide recommends surrounds on the same level as the side channels, but just checking if anyone has had direct experience with it.
Additionally, my in-ceiling speakers are slightly offset and the TV does not sit perfectly between them on the left/right plane. Would that suggest that their use as surrounds may be sub-optimal?
