The Tannoy CMS 6.5-15 is a professional-grade, ultra-wide bandwidth ceiling monitor speaker engineered for high-performance audio in distributed sound and background music systems. It is the largest model in Tannoy's CMS (Contractor Monitor Series) line, built around the company's iconic 6.5-inch Dual Concentric™ point source driver. This driver technology combines a 6.5-inch 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 to create a single, coherent point source. This design eliminates the phase interference and beaming issues common with conventional two-way speakers, ensuring consistent, high-fidelity coverage across the listening area.

Engineered for versatile commercial installation, the CMS 6.5-15 delivers a powerful 100 watts continuous power handling (400 watts peak) and an extended frequency response of 45 Hz to 50 kHz, enabling it to function effectively as a main speaker in high-quality music systems, not just for paging. It 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. The open-box unit includes essential accessories like the C-ring tile bridge for suspended ceiling installation, a tile support plate, and a paint mask for a clean, professional finish.
