Tannoy adds powerful in-ceiling loudspeaker 1201DC to its CMS line

Tannoy in-ceiling loudspeaker CMS 1201DC Tannoy debuted its new CMS 1201DC in ceiling loudspeaker at InfoComm 2010 in Las Vegas. The CMS 1201DC is a large format in-ceiling loudspeaker device conceived, designed and built to complement Tannoy’s existing CMS range. 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 new evolution of the high power handling 12” (300mm) Dual Concentric point source driver, the CMS 1201DC is designed to deliver best performance for the most even beamwidth and pattern control over a wide frequency range.
The new Dual Concentric drive assembly features a treated mid-bass cone and double rolled cambric surround for high sensitivity, as well as a 1.34” (34mm) aluminium dome with ferrofluid cooled Neodymium magnet assembly and a newly designed waveguide for the high frequency unit. These two drivers merge into one with the high frequency mounted in the throat of the mid-bass; coincidentally aligning both transducers to a point source for a uniform response over a controlled 90 degree coverage area.
All Tannoy ceiling loudspeakers are simple to design into a wide variety of applications using Tannoy's Ease Address design software. The software calculates the optimum spacing and performance with the input of some simple parameters.
Each device comprises of three discrete components: the loudspeaker assembly (mounted on ported steel baffle), a separate 79 litre (2.8 cubic feet) steel back-can with multiple mounting points and a white powder-coated steel grille and moulded bevel cover.
The custom engineered powder coated steel back-can has been designed to cater for all conceivable installation possibilities making the CMS 1201DC extremely versatile. Internally dampened with 11m OSB2 board, the addition of the back-can provides exceptional low frequency performance on a par with conventional wooden enclosure loudspeakers – but from an in-ceiling format. Steel mounting lugs allow for fitting to a Unistrut roof rail system in a variety of configurations both directly or via secondary prefixed cross struts. The device can also be hung via 4 top-mounted eye bolts, or as a further alternative, the design also caters for a single point central hang via M10 or 3/8 UNC screwed rod – made easy thanks to the slotted mounting saddle on the top of the back-can.
Mounting of the loudspeaker assembly to the pre-installed back-can is a one man job thanks to the common sense design approach. One edge of the baffle clips onto the steel box to hold it in place while the installer secures the assembly in place. Connection is simple via terminal barrier strips inside the can, easily accessible via 20mm and 29mm conduit knockouts on all 5 sides of the can. Saving time and man-power during installation has been a driving factor behind the design of the CMS 1201 system.
The CMS 1201 is available in both a standard low-impedance variant (CMS 1201DC) and a low insertion loss 60W line transformer-equipped version (CMS 1201DCt) for use on 70V or 100V distributed lines. Various standard tappings are configurable on the transformer before screwing driver assembly into the back can. If later adjustment to the level is required the baffle can be hung from the can via a hinged edge, leaving both hands free to make the required adjustment.
As with all of Tannoy’s CMS in-ceiling loudspeakers, the CMS 1201DC benefits from a 5-year warranty.
