TANNOY CMS 803DC BM ลำโพงติดเพดาน 8" Ceiling Speaker with 70/100V Transformer and Low Impedance Operation, Blind Mount Version

The Tannoy CMS 803DC 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 803DC 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 featuresrevolutionary 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 onand off-axis. The re-designed baffle provides a subtle extension to the waveguide effect for additional sonic benefits. 

The CMS 803DC 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 803DC 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 803DC is available in two variants. The BM (Blind Mount) version is supplied with an integral back-can, ready to install as a single unit, while the CMS 803DC PI (Pre-Install) is supplied without a back-can (separate back-can available). 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.
