- Powder-Coated Steel Construction For Rigidity In Commercial Ceiling Builds
- UL Listed For Plenum-Rated Installations To Satisfy Commercial Code Requirements
- Compatible With PS-C85 Family For Streamlined Specification Across Projects
- Supports Drop-Ceiling T-Bar Grid And Standard Drywall Applications
- Improves Bass Performance By Providing A Sealed Acoustic Volume Behind The Driver
- Contains Sound Within The Enclosure To Reduce Bleed Into Shared Plenum Spaces
The Sonance PS-C85BB is a dedicated acoustic back box engineered to pair with the PS-C85RTBF loudspeaker baffle in commercial installed audio environments. It is built for integrators who need a compliant, acoustically controlled enclosure for the PS-C85RT in-ceiling loudspeaker without improvising a solution or relying on the plenum cavity alone. Powder-coated steel construction keeps the assembly rigid and durable across the mechanical stresses typical in commercial builds.
UL listing for plenum-rated installations makes this back box a code-compliant choice for office buildings, hospitality venues, retail environments, and any commercial space where ceiling plenum certification is required by code or by the project specification. The enclosure supports both drop-ceiling T-bar grid installations using a compatible tile bridge and standard drywall ceilings, giving integrators flexibility across different ceiling types on the same project. By providing a sealed acoustic volume behind the driver, the PS-C85BB measurably improves low-frequency performance and limits sound bleed into adjacent plenum spaces, which is a critical concern in open-plan commercial environments with shared ceiling plenums.
