The Tannoy CMS-1201-DC is a professional 12-inch full-range ceiling loudspeaker designed for high-performance audio in large commercial installation applications. This model features Tannoy's proprietary Dual Concentric driver technology, where a high-frequency compression driver is mounted concentrically at the center of a large 12-inch bass/midrange cone. This design ensures that sound from both drivers originates from the same acoustic point, resulting in exceptional phase coherence, precise stereo imaging, and a wide, uniform dispersion pattern. The speaker is engineered for flush mounting into ceilings, with a low-profile, paintable grille that allows it to blend discreetly into the architectural environment while delivering powerful, articulate audio for background music, paging, and voice reinforcement in spaces such as auditoriums, large retail stores, houses of worship, and transportation hubs.

The loudspeaker incorporates a built-in multi-tap transformer for seamless integration into constant-voltage (70V/100V) distributed audio systems. This allows installers to select the appropriate power tap to match the speaker's output level to the specific acoustic requirements of the zone, simplifying the design of large-scale sound systems where many speakers are driven from a single amplifier over long cable runs. The Dual Concentric design minimizes beaming and provides consistent off-axis response, ensuring even coverage throughout the listening area. The enclosure is constructed from fire-retardant materials, meeting safety standards for commercial installations, and is built to deliver robust, full-range sound with high efficiency and output capability.

For system integrators and designers, the Tannoy CMS-1201-DC offers a premium solution for demanding commercial audio projects. Its combination of large-format coaxial technology, transformer-based operation, and professional installation features makes it a reliable choice for applications where both high sound pressure levels and superior audio quality are required. This loudspeaker is capable of filling large spaces with clear, coherent sound, making it an ideal component for comprehensive commercial sound reinforcement systems.
