Sonance PS-C85RT – 8-Inch Pro Series High-Output In-Ceiling Speaker

Product Overview

The Sonance PS-C85RT is an 8-inch high-output in-ceiling loudspeaker built for commercial sound reinforcement where extended low frequency and consistent SPL matter. It pairs an 8-inch aluminum cone woofer with a 1.4-inch neodymium compression driver on a field-selectable horn, giving integrators one enclosure that covers background and foreground music duty in demanding spaces.

Product Description

Part of the Sonance Pro Series High Output family, the PS-C85RT (Black, RAL 7021) is engineered for restaurants, retail floors, and houses of worship that need more headroom than a standard in-ceiling speaker can deliver. The coaxial driver arrangement keeps vocal clarity and bass output aligned from a single low-profile enclosure, so contractors can cover larger rooms with fewer drops. A field-selectable 120-degree or 80-degree dispersion pattern lets the same speaker adapt to open-plan ceilings or narrower, high-ceiling throws without swapping hardware. An integrated 70V/100V transformer with 120W, 60W, and 30W taps (plus a 70V 15W tap) makes the PS-C85RT equally at home on a distributed 70V/100V line or wired at 8 ohms for a dedicated amplifier zone. The steel grille and PC/ABS, powder-coated enclosure are built to hold up under daily commercial use, and the speaker carries UL 1480A, UL 2043, NFPA 90A, and NFPA 70 listings for plenum-rated installations. For integrators comparing options, browsing in-ceiling speakers alongside the PS-C85RT helps confirm it is the right fit before ordering matching grilles, back boxes, or mounting brackets.
