Tannoy CMS 803DC PI 8″ Full Range Ceiling Loudspeaker with Dual Concentric Driver

The CMS 803DC PI 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 certified CMS 803DC PI delivers wide and consistent broadband directivity with enhanced intelligibility – plus highly accurate and linear response.
