SpkrShell Architectural SL1 In-Ceiling Wireless Speaker Enclosure for Sonos

The SpkrShell Architectural SL1-S In-Ceiling Enclosure allows you to easily install select SONOS® speakers like ONE, ONE SL or the older PLAY:1 series, or similar sized, wireless streaming powered speakers in-ceiling, or even in-wall* in some instances! Basically, these will work anywhere you have space in your ceiling/wall and available always-on power!

Finally, you can use your wireless audio system speakers virtually anywhere with a clean professional installed look! Now you can easily install your ONE series wireless speakers in-ceiling as surround expansion for your compatible Sonos sound bar, or put outside in a cover patio. How about your Kitchen, or even a bathroom for premium sound anywhere!

This enclosure includes your option of a moisture-resistant white paintable Round or Square grill to best match your décor.

The unique design provides passive ventilation for your speaker, while the included back-cover provides a proper barrier between wall cavity and living space, this is ideal in situations for the enclosure may come in-contact 'IC' with insulation. This back-cover also helps with room to room sound leakage and acts as a vapor barrier.

The UL listed junction box is Romex® ready with Wago® lever nuts, and a convenient power switch for safe servicing, it simply hardwires wires into any standard 110 VAC circuit. All parts accessible from in-room by just removing the front grill.

As with all of our enclosure, this enclosure is made almost entirely from RF permissive plastics, with the exception of the grille. This helps insure our enclosure poses as little RF interference between your wireless signal and speaker as possible.

The speaker-forward design improves output and bass response, with wide sound dispersion. And your speakers features like voice Assistant can still work with our voice-cavity design built-in. 

Sonos speaker products shown is for illustration only and must be purchased separately, speakers are NOT included with the enclosure.

Electrical wiring knowledge needed to install. If you are not sure how to do this please contact a licensed professional for installation. Electrical collar and Junction box are plastic. Should be GFCI or better protect when installed in damp locations.

Moisture-Resistant (not waterproof) rating applies when installed out of direct weather and water spray, mounted in-ceiling, in a rated ceiling material with junction box and grille properly installed. When used with one of the 3 compatible speakers (Sonos One, Sonos SL, Sonos Play:1) which are all humidity resistant.

In-Wall Use is possible provided the wall depth is at least 4.9" from the finished surface to the back of the cavity. This product will NOT fit a standard 2x4" wall. This may adversely affect moisture resistant rating depending on your application.

Retrofit Install enclosure is designed for retro-fit installation, simply cut hole, attach electrical connection, and secure mounting dogs.

New Construction Install If you have new construction, pre-drywall, you should purchase one our  PCRB Rough-In Brackets which allows your contractors to create a clean ready to install spot for your SL1-S enclosure, brackets sold separately.

Drop Ceiling install is simple with our Drop-Ceiling Support Bracket, simply cut out the hole in your tile using the provided template that comes with the SL1-S enclosure, place bracket between SL1-S enclosure and tile, and secure mounting dogs. The bracket transfers the weight off of the tile to the grid, helping reduce tile sag or breakage over time.
