The CMS 801 PI 8 OHM BACKCAN is an acoustically enhanced zinc plated steel back can designed for the pre-installation of CMS 801 PI loudspeakers in newly constructed, non-suspended ceilings. Early installation of the low profile back can is fast and simple via the included flexible metal straps, and significantly reduces the amount of time required for project finalisation. Phoenix * connectors are provided for input and link output. Optional plaster (mud) rings are also available separately to identify pre-wiring locations.
