Description

4″ Full Range Directional Ceiling Loudspeaker with Dual Concentric Driver for Installation Applications (Blind Mount)

The CMS 403DCE is a full bandwidth 160-Watt high sensitivity loudspeaker that utilises our third generation Ceiling Monitor System technology (CMS 3.0). Thanks to an all-new proprietary 4″ Dual Concentric point-source driver with Omnimagnet technology on a Torus Ogive Waveguide, the CMS 403DCE delivers wide and consistent broadband directivity with enhanced intelligibility – plus highly accurate and linear response.

 

Adjustable Tilt Angle

Specifically designed with a self-aligning 3 way clamp system for fast, simple and cost effective installation, the CMS 403DCE can be angled towards the listener within the fixed ceiling-mounting ring. By discreetly pivoting the loudspeaker towards the desired area of coverage, the challenge of speaker placement in a less than ideal room is easily overcome.

 

Optimised for Installation

Equipped with a low-insertion loss 30 W transformer with convenient front panel tap switching, CMS 403DCE features an integral ABS back-can with removable locking screw terminal connector and loop-thru functionality. The paintable powder coated steel mesh grille with dust protection, two tile support rails and one C-ring are all included. An optional plaster (mud) ring is available separately.

 

LAB GRUPPEN Ready

The CMS 403DCE 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.
