Based on an all-new evolution of Tannoy's proprietary Dual Concentric point-source driver, the CMS 603DC BM 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 603DC BM 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 architect friendly aesthetic appeal.

The CMS 603DC BM 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 60W, 30W and 15W, with an additional 7.5W tap for traditional constant voltage systems.

The CMS 603DC BM is supplied with an integral zinc plated steel back-can, ready to install as a single unit and feature 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 new 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.
