The CMS 803DC Q is a full bandwidth 360-Watt high sensitivity loudspeaker that utilises our third generation Ceiling Monitor System technology (CMS 3.0). The “Q” variant of CMS 803DC is specifically designed for high-ceiling applications, incorporating an extended waveguide design with a tight, uniform 70-degree conical dispersion pattern. Thanks to an all-new proprietary 8″ Dual Concentric point-source driver with Omnimagnet technology on a Torus Ogive Waveguide, the UL certified CMS 803DC Q delivers more consistent broadband directivity with enhanced intelligibility – plus highly accurate and linear response.
