Right on schedule, Sonos and Sonance are today announcing a new series of in-wall, in-ceiling, and weatherproof outdoor speakers. The collection of passive speakers — called Sonos Architectural by Sonance — is specifically designed to work with the Sonos Amp for built-in whole-home streaming audio.

The outdoor speaker, the first expressly built for Sonos, features a weatherproof design for year-round sound outside the home. It’s designed to withstand humidity, heat, water, salt spray, UV rays, and freezing temperatures. The in-wall and in-ceiling series features grilles of different shapes that can be painted to disappear into your home. The speakers can be automatically tuned to the room and its furnishings using Sonos Trueplay after first being wired back to a Sonos Amp.
