Details
The "Q" variant ceiling speaker, designed specifically for high-ceiling applications, incorporates a proprietary waveguide design with a tight, uniform 70-degree conical dispersion pattern. Based on an all-new evolution of Tannoy’s proprietary Dual Concentric point-source driver, the CMS 803DCQ 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 for more consistent 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 803DCQ also features extra clamp extension to accommodate thicker ceiling panels, and a locking design that prevents inadvertent over-screwing. Magnetic grille attachment enables easy removal and fitting for custom painting and tapping changes with grilles now available as either traditional style (inset in bezel) or new Arco™ style which conceals the entire unit for more architectfriendly aesthetic appeal.
The CMS 803DCQ 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 60 W transformer is included, with convenient front bezel switching for taps at 60 W, 30 W and 15 W, with an additional 70.7 W tap for traditional constant voltage systems.
The CMS 803DCQ is available with an integral back-can, ready to install as a single unit. The zinc plated steel back-cans have an integrated, recessed termination box. 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 classic grille, two tile support rails and one C-ring; Arco grille and plaster (mud) ring are available as optional accessories.- Features
