Tannoy CMS 803DC
8" Dual Concentric Ceiling Speaker, Blind Mount

OUR PART #  CMS803DC-BM


Tannoy's CMS 803DC is a full bandwidth, high sensitivity loudspeaker with remarkable articulation and dispersion characteristics. This loudspeaker was created to be resilient, practical, and long-lasting.

The new Dual Concentric driver features Omnimagnet™ technology and unique Torus Ogive Waveguide™ device, which work together to provide more consistent and controlled directivity and high frequency response. The driver is capable of delivering 112dB average SPL at 1m on axis for great high performance, high volume audio.
