TANNOY CMS 803DC BM 8" Full Range Ceiling Loudspeaker with Dual Concentric Driver for Installation Applications (Blind Mount) (CMS 803DC BM) The CMS 803DC BM is a robust full-bandwidth 360-watt high-sensitivity loudspeaker, incorporating our advanced Ceiling Monitor System technology (CMS 3.0). With an exclusive 8" Dual Concentric point-source driver featuring Omnimagnet technology on a Torus Ogive Waveguide, this UL-certified speaker ensures expansive and consistent broadband directivity, significantly enhancing intelligibility while delivering an exceptionally accurate and linear response. Optimized for Installation The CMS 803DC BM is meticulously engineered with a 5-way self-aligning clamp system, ensuring swift, straightforward, and cost-effective installation. It integrates an acoustically enhanced zinc-plated steel back can and a removable locking screw terminal connector with loop-thru functionality. This model includes a low-insertion loss 60 W transformer featuring convenient front panel tap switching, a paintable powder-coated steel mesh grille providing dust protection, along with two tile support rails and a C-ring. For aesthetic concealment, an Arco-style grille designed to cover the entire unit and a plaster (mud) ring are available as separate accessories. LAB GRUPPEN Ready The CMS 803DC BM is finished in semi-matt white and optimized for use with LAB GRUPPEN LUCIA amplifiers, which accommodate up to 8 CMS Series loudspeakers per channel.
