1. Introduction
Thank you for purchasing this Tannoy product.
The CMS 1201DC is a powerful state-of-the-art large format in-ceiling loudspeaker device conceived, designed
and built to complement Tannoy’s class-leading CMS range. From the pioneers of point source and large format
ceiling speakers the CMS 1201DC is engineered from the ground up with superior full-range performance in mind
to handle demanding distributed sound applications such as ballrooms, shopping malls, sports halls, airports and
other high ceiling installations.
Built around a brand new evolution of the high power handling 12” (300 mm) Dual Concentric™ point source
driver, the CMS 1201DC delivers best-in-class performance for the most even beamwidth and pattern control
over the widest range of frequencies of any large format ceiling speaker. Coupled with exceptional clarity, ultra low
distortion, and high SPLs, Tannoy has again raised the bar to give the absolute cutting edge performance in ceiling
mounted loudspeaker technology.
The new Dual Concentric drive assembly features a treated mid-bass cone and double rolled cambric surround for
high sensitivity, as well as a 34 mm (1.34”) aluminium dome with ferrofluid-cooled Neodymium magnet assembly
and a newly designed waveguide for the high frequency unit. These two drivers seamlessly merge into one with the
high frequency mounted in the throat of the mid-bass; coincidentally aligning both transducers to a point source.
The result is a smooth, uniform response over a very controlled 90 degree coverage area – even in the highest
octaves.
