Model: PB1-C

Our In-Ceiling, Recessed-Mount Sonos Solution was invented by Audio/Video Installers to transform your Sonos speakers from tabletop to a professional in-ceiling setup. The PlayBox is tuned to not inhibit sound quality, interfere with wireless signals, nor reduce mic sensitivity (for voice-controlled speakers). 

Designed for an Architectural-vibe, the PlayBox Ceiling Model eliminates any visible cords or cables, for a clutter-free setup. Preferred by homeowners, businesses, architects, and designers, the PB1-C prevents unwanted tampering or damage, common with countertop speakers, while still delivering amazing sound quality from above.

Engineered for Demanding Environments, and built to last, the PlayBox by Thenos is manufactured using rugged metal materials, making it ideal for a multitude of applications within any home or business habitat.
