Description

The CMS 803DC BM is a full bandwidth 360-Watt high sensitivity loudspeaker that utilises our third generation Ceiling Monitor System technology (CMS 3.0). Thanks to an all-new proprietary 8″ Dual Concentric pointsource driver with Omnimagnet technology on a Torus Ogive Waveguide, the UL certifi ed CMS 803DC BM delivers wide and consistent broadband directivity with enhanced intelligibility – plus highly accurate and linear response.
