If I buy the Sonance ceiling speakers to use in my kitchen and connect them to the Sonos AMP do they have to play in a left/right stereo pair configuration or can they be configured to provide a mono type output similar to a single stereo speaker? I cannot place the speakers such that the listening positions will be right for a stereo pair output. I could use a couple of single stereo speakers but I have a slopped ceiling and I don’t see that any of those have pivoting tweeters.
