Overview

The CMS 603DC BM is a full bandwidth 320-Watt high sensitivity loudspeaker that utilises our third generation Ceiling Monitor System technology (CMS 3.0). Thanks to an all-new proprietary 6" Dual Concentric point-source driver with Omnimagnet technology on a Torus Ogive Waveguide, the UL certified CMS 603DC BM delivers wide and consistent broadband directivity with enhanced intelligibility – plus highly accurate and linear response.
