Description

TANNOY CMS 503DC BM 5" Full Range Ceiling Loudspeaker with Dual Concentric Driver for Installation Applications (Blind Mount) (CMS 503DC BM)

The CMS 503DC BM stands as a robust full-bandwidth 240-Watt high-sensitivity loudspeaker, embodying our state-of-the-art Ceiling Monitor System technology (CMS 3.0). It features an exclusive 5" Dual Concentric point-source driver equipped with Omnimagnet technology on a Torus Ogive Waveguide. This UL certified speaker ensures expansive, reliable broadband directivity, significantly enhancing intelligibility while delivering an exceptionally accurate and linear response.

Optimized for Installation

The CMS 503DC BM comes equipped with a purpose-built self-aligning 3-way clamp system for quick, easy, and cost-effective installation. Its acoustically enhanced zinc-plated steel back can features a removable locking screw terminal connector and loop-thru functionality. Additionally, it includes a low-insertion loss 30 W transformer with convenient front panel tap switching, a paintable powder-coated steel mesh grille with dust protection, two tile support rails, and a C-ring. For aesthetic purposes, an Arco style grille that conceals the entire unit and a plaster (mud) ring are available separately.

LAB GRUPPEN Ready

The CMS 503DC BM is finished in semi matt white and optimised for use with LAB GRUPPEN LUCIA amplifiers, which accommodate up to 8 CMS Series loudspeakers per channel.
