Dual Concentric Loudspeaker
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.
ICT (Inductive Coupling Technology) Models
The point source conguration of the Tannoy ICT driver’s mid-bass and tweeter sections ensures a wide and
controlled dispersion for optimum coverage, avoiding signicant energy losses in the vertical plane at the
crossover frequency, a aw inherent in typical two-way designs. The ICT (Inductive Coupling Technology)
drive unit also addresses two common component failures in background music systems: the tweeter and
the crossover. Use of wireless electromagnetic coupling to drive the tweeter means that no crossover is
required, making the ICT drive unit exceptionally reliable and ideal for applications where constant heavy
usage is the norm.
Eyeball variant
Specically 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 xed ceiling-mounting ring. By discreetly
pivoting the loudspeaker towards the desired area of coverage, the problems of difcult speaker placement
- particularly in less than perfect room congurations – are easily overcome.
“Q” variants
The new “Q” variant, designed specically for high-ceiling applications, incorporates a proprietary
waveguide design with a tight, uniform 70-degree conical dispersion pattern.
Low Prole
With a greatly reduced back-can depth, the ultra low-prole CMS 503DC LP has been engineered specically
for applications where ceiling cavity dimensions are a critical limiting factor. This specialized ceiling device
retains the exceptional sonic performance of the standard CMS 503DC, in a much shallower prole package,
achieving similar back-can volume by virtue of slightly larger diameter (and hole cut-out size).
BM (Blind Mount)
Version is supplied with an integral back-can, ready to install as a single unit.
PI (Pre-Install)
These are is supplied without a back-can (separate back-can available).

CMS 3.0 Series
CMS 3.0 at a glance
With a fundamental redesign of the Dual Concentric driver, the new CMS 3.0 range is our most advanced ceiling device
ever produced, providing better clarity and wider dispersion, as well as a range of mounting options to suit any application.
The available range means that whatever the challenges you face in an installation, CMS 3.0 will help overcome the limitations
of the space.
