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.

NOTE: This is a RESTOCK item that has had its box opened or has been repackaged. It may have minor cosmetic flaws and may have been sold to a customer and returned with a SINGLE speaker. Please contact your Sales Pro for more information on this and other products.

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.

Tannoy CMS 403DCe Features:

  • Advanced new Dual Concentric driver design utilizing Omnimagnet technology
  • Torus Ogive Waveguide device for improved broadband directivity
  • Tight, uniform 70° dispersion pattern forhigh-ceiling applications
  • Improved time alignment and phase coherence, delivering even better sonic performance
  • High power and high sensitivity with extended frequency response and very low distortion
  • Improved LF performance for applications where genuine bottom-end is a must
  • Low insertion-loss, 30 watt line transformer for a more powerful and dynamic performance
  • Convenient front-tapping switch for settings
  • Magnetically-adhering grille system for easy custom painting and optional Arco designer grilles for minimal architectural impact
  • Three-clamp, self-aligning mounting system
  • UV/weather resistant UL94V-0 ABS construction for structural integrity
  • Packaged with classic grille, tile rails and C-ring for quick and easy installation and simple stocking logistics
  • Five year warranty
