The CMS 1201SW BACKCAN is an acoustically enhanced zinc plated steel back can designed for the pre-installation of CMS 1201SW subwoofer in newly constructed, non-suspended ceilings. The back can features an internally dampened 79 litre (2.8 cubic feet) capacity and provides exceptional low frequency performance. Multiple installation options include: steel mounting lugs for fitting to a Unistrut roof rail system; suspension via 4 top-mounted eye bolts; and single point suspension M10 or 3/8″ UNC threaded rod. One-person installation is fast and simple, and significantly reduces the amount of time required for project finalisation. Phoenix* connectors are provided for input and link output.
