TANNOY CMS1201 SW ลำโพงติดเพดาน Ceiling Speaker
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. The CMS 1201SW is intended for
systems utilizing an external active crossover and separate amplifier channel for the subwoofer
loudspeaker(s). From the pioneers of point source and large format ceiling speakers the
CMS 1201SW 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. The CMS 1201SW features a high power handling 12” (300mm) bass driver featuring a 3” Copper Sandwich Voice Coil for low Power Compression and Triple Aluminum demodulating Rings for ultra-low Distortion. Tannoy has again raised the bar to give the absolute cutting edge performance in ceiling mounted loudspeaker technology.
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 be hung via 4 top-mounted eye bolts. Alternatively, the design caters for a single point hang via M10 or 3/8 UNC screwed rod. Mounting of the loudspeaker assembly to the preinstalled 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. The CMS 1201SW is available in both standard low-Z variant (CMS 1201SW) and 150 W line transformer-equipped version (CMS 1201SWT) for use on 70 V or 100 V distributed lines.
