CMS 1201SW
Introduction
Thank you for purchasing this Tannoy product. The CMS 1201SW is a powerful large format in-ceiling subwoofer loudspeaker device conceived, designed and built
to complement Tannoy's existing class-leading CMS range, or any full range system requiring extended bass response. Intended for systems utilizing an external
active crossover and separate amplifier channel for the subwoofers, the CMS 1201SW features a high power handling 12" (300 mm) bass driver featuring a 3" copper
sandwich voice coil for low power compression and triple aluminium demodulating rings for ultra-low distortion.
The custom-engineered powder coated steel back-can has been designed to cater for all conceivable installation possibilities, making the CMS 1201SW
extremely versatile. The internally-dampened 79 litre (2.8 cubic feet) back-can provides exceptional LF performance on a par with conventional wooden
enclosure loudspeakers. Steel mounting lugs allow for fitting to a Unistrut roof rail system or for suspension via 4 top-mounted eye bolts. Alternatively, the design
caters for a single point hang via M10 or 3/8 UNC screwed rod. Connection is simple via terminal barrier strips inside the can, easily accessible via 20 mm and 29 mm
conduit knockouts on all 5 sides of the can.
