The Sonos Architectural speakers will work with most amplifiers. However, you will not be able to take advantage of the TruePlay room-tuning capabilities with any amplifier other than Sonos Amp.                                        

The Sonos In-Ceiling by Sonance speakers use a cut-out hole that is 8 1/4" in diameter. If your existing hole is that size (or smaller), the Sonos speakers will fit but may require a small amount of drywall to be removed (if the hole is smaller than 8 1/4"). The Sonos In-Wall by Sonance speaker cut-out dimension are 7” x 10 3/4"; if your opening is the same size or smaller, the same rules apply. If your opening is larger than these holes, the speakers will not fit, and drywall work will be required to patch and recut a hole to fit your Sonos Architectural speakers.

We recommend placing your speakers in locations in the ceiling that will provide smooth and even balanced coverage in as many locations as possible in the room. If your room is large, we recommend a second pair of speakers to provide the room with the best coverage and the optimal listening experience.

The speakers should be installed above and slightly behind the primary seating position.

No, only the In-Wall and In-Ceiling speakers will support Trueplay. The Outdoor speakers will not, since the outdoor environment is not favourable to Trueplay.
