4" Coaxial In-Ceiling Loudspeaker for Installation Applications

The CVS 4 is a compact 160-Watt ceiling loudspeaker engineered to provide superb audio performance in both background and foreground music sound systems. Ideally suited for a wide variety of applications, from restaurants and hotels to houses of worship and businesses of all types, the CVS 4 offers the power handling, wide frequency response and low distortion more typically found in a studio reference monitor than a ceiling loudspeaker. The resulting sound is warm, with a nuanced and pristine clarity that envelopes the listener – without intruding.

Exceptional Sound and Reliability
The design comprises a 100 mm (4.00") mid-bass driver with a coaxially mounted 19 mm (0.75") high-frequency section mounted in a vented, injection moulded, paintable front baffle manufactured from UV/weather resistant UL94V-0 ABS material. The mineral loaded polypropylene cone material and nitrile rubber surround enhance durability and long-term reliability. This compact unit is specifically designed for applications requiring the combination of excellent sonic quality for music and speech reinforcement and exceptional reliability.

Comprehensive Installation Package
Supplied with an integral zinc-plated steel back can, with recessed termination box, the CVS 4 satisfies the vast majority of installation application requirements. The removable locking connector has 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. Security toggle clamps make for quick and easy installation, while two tile support rails and one C-ring are also included in the package. A plaster (mud) ring is available as an optional accessory.
