The product is sold in pairs, but the price is listed per individual item

The Tannoy CMS 403DCe is a full bandwidth, high power-handling and high sensitivity loudspeaker built around CMS 3.0 – the third generation of Tannoy’s revolutionary Ceiling Monitor System technology. Based on an all-new evolution of Tannoy’s proprietary Dual Concentric point-source driver, the CMS 403DCe has been fundamentally re-engineered to deliver wider and more consistent broadband directivity, even greater intelligibility, and a more accurate and linear response.

The new Dual Concentric driver design features revolutionary Omnimagnet technology and unique patent-pending Torus Ogive Waveguide device, together providing more consistent and controlled directivity along with improved high frequency response. Improved time-alignment and greater coherence between LF and HF results in a wider sweet spot for enhanced performance both on- and off-axis. The re-designed baffle provides a subtle extension to the waveguide effect for additional sonic benefits.

The CMS 403DCe also features extra clamp extension to accommodate thicker ceiling panels, and a locking design that prevents inadvertent over-screwing. Specifically designed for fast, simple and cost effective installation in new and existing buildings, the CMS 403DCe can be entirely angled towards the listener within the fixed ceiling-mounting ring. By discreetly pivoting the loudspeaker towards the desired area of coverage, the problems of difficult speaker placement - particularly in less than perfect room configurations – are easily overcome.

The CMS 403DCe utilizes a 16 ohm driver, making it ideal for use in high performance low impedance systems (with optimized performance when used in conjunction with Lab.gruppen LUCIA amplifiers). A low-insertion loss 30W transformer is included, with convenient front switching for taps at 30 W, 15 W and 7.5 W, with an additional 3.75 W tap for traditional constant voltage systems.

The CMS 403DCe is supplied with an integral back-can, ready to install as a single unit. The removable locking connector has screw terminals for secure wire termination and loop-thru facility. Strain relief is provided by a clamping mechanism for use with plenum-rated cable or conduit, while the new design’s spring-loaded and self-aligning clamps make for even quicker and easier installation. All models are supplied with two tile support rails and one C-ring; a plaster (mud) ring is available as an optional accessory.
