Tannoy CMS1201DCT 12" Full Range Ceiling Loudspeaker with Dual Concentric Driver and Transformer
Description Tannoy CMS1201DCT 12" Full Range Ceiling Loudspeaker with Dual Concentric Driver and Transformer The CMS 1201DCT is a professionally designed full bandwidth 800-Watt high sensitivity loudspeaker that is capable of utilizing our proprietary 12" Dual Concentric point-source driver, which is capable of delivering an consistent broadband directivity (90 Degree conical) that comes along with enhanced intelligibility - plus highly accurate and linear response. Full Range DriverCMS 1201DCT's 12" (300 mm) Dual Concentric constant directivity driver comes featuring a treated cone, plus a 1.34" (34 mm) aluminium dome that comes with neodymium magnet system intended for 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). A low insertion loss 60 W line transformer multiple taps is made being provided for 70 V and 100 V line systems, as well as an 8 Ohm direct input. Optimised for InstallationThe custom-engineered powder coated steel back-can and grille assembly (available separately) has been designed for catering to all conceivable installation possibilities, that makes the CMS 1201DCT 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 made for allowing the 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 is 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 possible to amount to considerable savings in large-scale projects. LAB GRUPPEN ReadyThe CMS 1201DCT is optimized for working in conjunction along with LAB GRUPPEN amplification.
