The Tannoy CMS65-15 is a professional-grade ceiling monitor speaker engineered as the largest model in Tannoy's Contractor Monitor Series (CMS), specifically designed for high-performance audio in distributed sound and background music systems. Built around Tannoy's iconic 6.5-inch Dual Concentric point source driver technology, this speaker combines a treated paper pulp cone for low frequencies with a 1-inch titanium dome tweeter mounted at its acoustic center, working through a central tulip waveguide. This innovative design creates a single, coherent point source that effectively eliminates the phase interference and beaming issues common with conventional two-way speakers, ensuring consistent, high-fidelity coverage across the entire listening area.

Performance specifications are impressive for an in-ceiling design, with the CMS65-15 delivering 100 watts continuous power handling (400 watts peak) and an extended frequency response of 45 Hz to 50 kHz. This ultra-wide bandwidth enables the speaker to function effectively as a main speaker in high-quality music systems, not merely for paging or background announcements. The speaker features a robust 15-watt, 70V/100V multi-tap line transformer, accessible via a front-panel rotary switch that allows easy selection of power taps without removing the speaker from the ceiling—a significant convenience for commercial installers performing system adjustments after installation.

Engineered for versatile commercial installation environments, the CMS65-15 includes essential accessories for professional mounting. The open-box unit comes with a C-ring tile bridge for suspended ceiling installation, a tile support plate, and a paint mask for achieving a clean, professional finish that blends seamlessly with surrounding surfaces. Whether deployed in retail spaces, corporate facilities, hospitality venues, or educational institutions, this speaker delivers the sonic precision and installation flexibility expected from Tannoy's professional audio lineage.
