The CVS 4 is a 100 mm (4") ceiling speaker supplied with an integral zinc-plated steel back can. The recessed termination box allows the use of a removable locking connector with screw terminals for secure wire termination and "loop through" facility. Strain relief is provided by a clamping mechanism for use with plenum rated cable or conduit. The drive unit itself is mounted in a vented, injection moulded, paintable front baffle manufactured from UV / weather resistant UL94 V-0 ABS material.
An integral low insertion loss 30 W line transformer uses an easily accessible front baffle mounted rotary tapping switch to select between low impedance and 70 V or 100 V operation.
