Tannoy CMS1201DC 12" Full Range Ceiling Loudspeaker with Dual Concentric Driver

Tannoy CMS1201DC 12" Full Range Ceiling Loudspeaker with Dual Concentric Driver

The CMS 1201DC is a professionally designed full bandwidth 800-Watt high sensitivity loudspeaker that comes utilizing our proprietary 12" Dual Concentric point-source driver, which is capable of delivering an consistent broadband directivity (90° conical) along with enhanced intelligibility – plus highly accurate and linear response.

Full Range Driver
CMS 1201DC’s 12" (300 mm) Dual Concentric constant directivity driver comes featuring a treated cone, and an added 1.34" (34 mm) aluminium dome that comes along with neodymium magnet system intended for having an powerful and highly intelligible music and speech reproduction. Frequency response ranges from 60 Hz - 20 kHz (-3 dB) along with a maximum SPL of 126 dB (1 m, on axis).

Optimised for Installation
The custom-engineered powder coated steel back-can and grille assembly (both available separately) have been designed for catering to all conceivable installation possibilities, that makes the CMS 1201DC extremely versatile. The internally-dampened 79 litre (2.8 cubic feet) back-can is capable of providing an exceptional LF performance that is easily on par along with conventional wooden enclosure loudspeakers. Steel mounting lugs are allowing for fitting to a Unistrut roof rail system or for suspension with the use of 4 top-mounted eye bolts. Alternatively, the design is allowing for a single point suspension, which are possible to be handled with the use of M10 or 3/8" UNC screwed rod. Connection is made quick and simple with the use of terminal barrier strips inside the can, which are easily accessed by using 20 and 29 mm conduit knockouts on all 5 sides. Installation is possible to be facilitated by a single person, which are capable to amount to considerable savings in large-scale projects.
