Tannoy CMS 803DC PI 8" 70V Full Range Ceiling Loudspeaker with Dual Concentric Driver - Pair

Description

Details

The CMS 803DC PI is a full bandwidth 360-Watt high sensitivity loudspeaker that utilizes our third generation Ceiling Monitor System technology (CMS 3.0). 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 PI delivers wide and consistent broadband directivity with enhanced intelligibility - plus highly accurate and linear response.

Optimized for Installation

Specifically designed with a self-aligning 5-way clamp system for fast, simple and cost-effective installation, CMS 803DC PI also features extra clamp extension to accommodate thicker ceiling panels, and a locking design that prevents over-tightening. A low-insertion loss 60 W transformer with convenient front panel tap switching, paintable powder coated steel mesh grille with dust protection, two tile support rails, and one C-ring are all included. An Arco style grille, which conceals the entire unit for aesthetic purposes, a back can, and plaster (mud) ring are available separately.

LAB GRUPPEN Ready

The CMS 803DC PI is finished in semi-matte white and optimised for use with LAB GRUPPEN LUCIA amplifiers, which accommodate up to 8 CMS Series loudspeakers per channel.
