Atlas Sound 96-8-7 – 8-Inch Flanged Round Back Enclosure 7-Inch Deep

Product Overview

The Atlas Sound 96-8-7 is an 8-inch flanged round back enclosure measuring 7 inches deep, designed for in-ceiling loudspeaker installations requiring a dedicated acoustic back can. It is constructed with fiberglass fill to improve low-frequency performance and reduce acoustic bleed between adjacent spaces. The 96-8-7 is used by AV installers and integrators in commercial and residential projects where an enclosed back cavity is required by fire code or acoustic design.

Product Description

The 96-8-7 enclosure is engineered to pair with Atlas Sound 8-inch round in-ceiling loudspeakers, providing a controlled back volume that improves bass response and minimizes sound transmission to adjacent rooms. The flanged design allows secure attachment to the ceiling structure, and the round profile matches standard 8-inch cut-out dimensions used across most in-ceiling speaker lines. The 7-inch depth accommodates typical above-ceiling plenum clearances found in commercial construction, and the fiberglass fill acts as an acoustic damping material to reduce internal standing waves and improve overall frequency response. The enclosure is also useful in applications where fire or building codes require speakers in return-air plenums to use listed back cans, protecting the speaker from plenum air pressure and providing a measure of fire containment. The sheet metal construction provides structural rigidity while remaining lightweight for easy single-person installation. The flange provides a positive seal against the ceiling tile or drywall surface, reducing air gaps. This enclosure is an essential component for commercial AV installations targeting predictable acoustic performance across multiple zones.
