This is a finishing kit, not a speaker. It is supplied as a pair of square adapters with matching grilles, and its purpose is to change the visible aperture of round 8-inch In-Ceiling Speakers by Sonos and Sonance from a circle to a square. Sonance offers the same conversion across its architectural range, where the square adapter is described as converting round speakers to a square appearance.
Designers and integrators specify this for a straightforward reason: ceilings usually already contain square elements - recessed downlights, HVAC diffusers, access panels, sprinkler plates - and matching the speaker aperture to that geometry makes the audio system read as part of the ceiling grid rather than as an addition to it. It is a common request in modern residential builds, hospitality spaces, and commercial fit-outs.
The grille keeps the trimless, flush-to-ceiling profile of the Sonos Architectural line and the custom perforation pattern Sonos specifies. It is paintable, so it can be finished to the exact ceiling color; use light coats so the perforations stay open and the top end is not dulled. Each square measures 11.16 inches across in the 8-inch size, and the kit ships as a pair to match how the speakers are sold.
