Sonance PS-C85RTBF – 8-Inch Pro Series In-Ceiling Baffle Speaker
Product Overview
The Sonance PS-C85RTBF is the baffle-only version of the Pro Series High Output 8-inch in-ceiling speaker, designed to install into a separately purchased back box for new-construction commercial projects. It delivers the same coaxial 8-inch woofer and 1.4-inch compression driver performance as the standard PS-C85RT in a format built for plenum-isolated back-box mounting.
Product Description
As part of the Sonance Pro Series High Output lineup, the PS-C85RTBF (Black, RAL 7021) pairs an 8-inch aluminum cone woofer, Santoprene surround, with a 1.4-inch aluminum dome compression driver for extended low-frequency output and high SPL in commercial spaces. Because it is a baffle-only loudspeaker, it must be installed with the matching PS-C85BB back box, giving specifying engineers control over enclosure volume and plenum separation on larger jobs. Field-selectable 120-degree or 80-degree dispersion lets one SKU serve open floor plans and narrower, high-ceiling throws alike, and the integrated distributed-audio transformer switches between 70V/100V taps (120W, 60W, 30W) or a 70V 15W tap for lower-output zones. The PC/ABS enclosure, steel grille, and powder-coated finish are rated UL 1480A, UL 2043, and NFPA 90A/70 compliant for above-ceiling plenum installation. Integrators sourcing the PS-C85RTBF for a new build can review the broader Sonance in-ceiling speakers lineup to plan matching back boxes, tile bridges, and grille finishes in the same order.
