About this product

12" Ceiling Subwoofer for Installation Applications

CMS 1201SW

The CMS 1201SW is a passive 1,600-Watt subwoofer and is ideally-suited for use with the CMS 3.0 range of ceiling monitor systems, or any full range system requiring extended bass response. Thanks to its powerful 12" long throw low frequency driver, the CMS 1201SW delivers dynamic LF extension and premium grade audio for installed music and speech reinforcement applications. 

Low Frequency Driver

Intended for systems utilising an external active crossover and separate amplifier channels for the subwoofers, CMS 1201SW’s 12" (300 mm) bass driver features a 3" copper sandwich voice coil for low power compression, and triple aluminium demodulating rings for ultra-low distortion.

Optimised for Installation

The custom-engineered powder coated steel back-can and grille assembly (both available separately) have been designed to cater to all conceivable installation possibilities, making the CMS 1201SW extremely versatile. The internally-damped 79 litre (2.8 cubic feet) back-can provides exceptional LF performance that is easily on 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 allows for a single point suspension, which can be handled via the use of M10 or 3/8" UNC screwed rod. Connection is quick and simple using terminal barrier strips inside the can, which are easily accessed via 20 and 29 mm conduit knockouts on all 5 sides. Installation can be facilitated by a single person, which can amount to considerable savings in large-scale projects.

LAB GRUPPEN Ready

The CMS 1201SW is optimised to work in conjunction with LAB GRUPPEN amplification.
