TANNOY CMS 603DC BM 6" Full Range Ceiling Loudspeaker with Dual Concentric Driver for Installation Applications (Blind Mount) (CMS 603DC BM) The CMS 603DC BM represents a powerful full-bandwidth 320-watt high-sensitivity loudspeaker, incorporating our advanced Ceiling Monitor System technology (CMS 3.0). Featuring an exclusive 6" Dual Concentric point-source driver equipped with Omnimagnet technology on a Torus Ogive Waveguide, this UL-certified speaker ensures expansive and uniform broadband directivity, significantly enhancing intelligibility while delivering an exceptionally accurate and linear response. Optimized for Installation The CMS 603DC BM is meticulously crafted with a 4-way self-aligning clamp system, ensuring swift, straightforward, and cost-effective installation. It incorporates an acoustically enhanced zinc-plated steel back can and a removable locking screw terminal connector with loop-thru functionality. Included are a low-insertion loss 60 W transformer featuring user-friendly front panel tap switching, a paintable powder-coated steel mesh grille providing dust protection, along with two tile support rails and a C-ring. Separate purchases offer an Arco-style grille designed for complete unit concealment and a plaster (mud) ring for specific aesthetic preferences. LAB GRUPPEN Ready The CMS 603DC 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.
