The Tannoy CMS 1201 BACKCAN is an acoustically enhanced, zinc-plated steel back can designed for the pre-installation of CMS 1201DC loudspeakers or CMS 1201SW subwoofers in suspended and non-suspended ceilings. The back can and its containment can be installed before the ceiling is finished, streamlining project completion.
It has a damped 79-litre (2.8 cubic feet) internal volume to improve low-frequency performance. The design offers multiple installation options like steel mounting lugs for Unistrut systems, eye bolts for suspension, or a single-point threaded rod. This allows for quick, single-person installation. Phoenix connectors are included for easy input and link output wiring.
