The CMS 403DCE is a full bandwidth 160-Watt high sensitivity loudspeaker that utilises our third generation Ceiling Monitor System technology (CMS 3.0). Thanks to an all-new proprietary 4″ Dual Concentric point-source driver with Omnimagnet technology on a Torus Ogive Waveguide, the CMS 403DCE delivers wide and consistent broadband directivity with enhanced intelligibility – plus highly accurate and linear response.
