The Sonance PS-C6R is a high-performance, in-ceiling loudspeaker from Sonance's Professional Series, engineered for commercial audio applications demanding both superior sound quality and installation flexibility. This model is configured as a single stereo, two-way speaker, meaning it incorporates two independent sound channels (left and right) within a single ceiling-mounted enclosure, each channel driven by its own dedicated 6.5-inch woofer and 1-inch tweeter with a crossover network. This innovative design effectively halves the number of ceiling cutouts required for a stereo audio zone, providing a significant advantage in architectural spaces where ceiling real estate is limited or where a minimalist aesthetic with fewer visible grilles is desired. It is ideally suited for background music and paging in restaurants, retail stores, offices, and hospitality venues where a discrete yet full-range stereo image is beneficial.

Acoustically, the speaker utilizes a two-way design for each channel to ensure accurate frequency reproduction. The 6.5-inch woofers are constructed from mineral-filled polypropylene, a material chosen for its rigidity and damping characteristics, providing solid mid-bass response. Each woofer is paired with a 1-inch soft-dome tweeter, ferrofluid-cooled for enhanced power handling and thermal stability, delivering clear and detailed high frequencies. The speakers are mounted on a rigid, die-cast aluminum back-can that minimizes resonance and provides a secure mounting platform. A key professional feature is the inclusion of a multi-tap transformer with several selectable power settings, allowing the speaker to be integrated into standard 70V or 100V constant-voltage commercial sound systems, as well as an 8-ohm direct mode for use with traditional stereo amplifiers in higher-fidelity applications.

Installation is streamlined through user-adjustable features and a thoughtful mechanical design. The speaker includes a rotating cam system with integrated dog-leg clamps for quick, tool-free securement into the ceiling after the wiring is connected. The paintable, low-profile grille is magnetically attached, allowing for easy removal for painting and driver access. The transformer taps and a high-frequency trim switch are accessible after installation, enabling fine-tuning to match the amplifier's capacity and compensate for room acoustics. Finished in white, the PS-C6R presents a clean, unobtrusive appearance. By combining stereo reproduction, commercial voltage compatibility, and installer-friendly features in one unit, this speaker offers a versatile and space-efficient solution for delivering high-quality distributed audio in a wide range of professional environments.
