TANNOY CVS 4 MICRO (EN 54)
4″ Coaxial In-Ceiling Loudspeaker with Shallow Back Can for Installation Applications (EN 54 Certified)

CVS 4 MICRO (EN 54)

The CVS 4 MICRO (EN 54) is a compact 160-Watt shallow back can 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 MICRO (EN 54) 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. EN 54-24 certification for fire detection and fire alarm systems makes the CVS 4 MICRO (EN 54) the perfect choice where safety is a top priority.

Optimised for Installation

The design comprises a 100 mm (4.00″) mid bass driver with a coaxially mounted 19 mm (0.75″) high frequency section mounted in an injection moulded semi matt white front baffle made of UV/weather resistant UL 94 V-0 ABS material that fits unobtrusively into any environment. The mineral loaded polypropylene cone material and nitrile rubber surround enhance durability and long-term reliability. Thanks to the shallow back can depth of less than 4″ (98.3 mm), CVS 4 MICRO (EN 54) is perfect for applications where above-ceiling space is limited, but exceptional sonic quality and reliability are a requirement.

Comprehensive Installation Package

Supplied with an integral plated steel shallow back can, Phoenix* connector with steel cover, and an EN 54 compliant strain relief clamping mechanism for fire rated cable, the CVS 4 MICRO (EN 54) satisfies the vast majority of installation application requirements. Input is via a low insertion loss 15 W line transformer with multiple taps for 70 V and 100 V line systems or 6 Ohm direct input. Installation is quick and easy with two tile support rails and one C-ring included in the package. A plaster (mud) ring is available as an optional accessory.
