Tannoy CVS 4 4" Coaxial In-Ceiling Speaker | 70V/100V

Tannoy CVS 4 4" Coaxial In-Ceiling Speaker for Commercial Installation

The Tannoy CVS 4 In-Ceiling Speaker is a UL 1480-certified, full-range coaxial loudspeaker engineered for permanent installation in commercial, institutional, and life-safety signaling environments. It handles 40 watts continuous and 160 watts peak power, delivers a rated maximum SPL of 103 dB average and 109 dB peak, and covers a 90-degree conical dispersion pattern — making it a reliable choice for consistent, intelligible audio across large ceiling grids.

For integrators sourcing the best UL 1480 ceiling speaker for commercial installation — whether in offices, retail spaces, hospitality venues, or healthcare facilities — the CVS 4 stands apart with its dual UL 1480 and UL 2043 certifications, enabling compliant deployment in both fire-protected signaling systems and air-handling plenum spaces. Its low insertion loss 30-watt line transformer with a front-accessible tapping switch simplifies commissioning on 70V and 100V distributed audio systems, while the 6-ohm direct input option preserves flexibility for low-impedance configurations.

The CVS 4 pairs a 4-inch mineral loaded polypropylene cone woofer with a 0.75-inch ferrofluid-cooled neodymium soft dome tweeter in a true coaxial arrangement, achieving wide constant directivity dispersion from 85 Hz to 19 kHz (–3 dB). Its UV and weather-resistant UL 94 V-0 ABS baffle and plated steel fire can enclosure meet the physical demands of long-term installation. The Phoenix connector with steel cover and strain relief clamping mechanism accommodates fire-rated cable, supporting code-compliant wiring in demanding environments.

Key Features of the Tannoy CVS 4 Commercial Ceiling Speaker

• Dual UL Certification: Carries both UL 1480 (fire-protected signaling systems) and UL 2043 (air-handling spaces) ratings, enabling compliant installation in plenum ceilings and life-safety applications without additional hardware.
• Coaxial Full-Range Driver: A 4-inch mineral loaded polypropylene cone paired with a 0.75-inch ferrofluid-cooled neodymium soft dome tweeter delivers full-range coverage from a single point source, improving time alignment and off-axis clarity.
• Wide Constant Directivity Dispersion: A nominal 90-degree conical coverage angle (102 degrees averaged 1 kHz–6 kHz) ensures consistent SPL and tonal balance across the listening area, reducing the number of speakers needed per zone.
• 70V / 100V Transformer with Accessible Tap Switch: The low insertion loss 30W line transformer includes a front-mounted rotary tapping switch with multiple power settings, eliminating the need to remove the speaker for level adjustments during commissioning.
• Fire-Rated Cable Termination: The Phoenix connector with steel cover and strain relief clamping mechanism accepts conduit up to 22 mm and supports loop-through wiring, streamlining daisy-chain installations in fire-alarm and paging systems.
• Durable, Weather-Resistant Construction: UL 94 V-0 rated ABS baffle and zinc-plated steel back can withstand UV exposure and long-term environmental stress, supporting reliable performance in demanding installation conditions.
• Complete Mounting Hardware Included: Ships with a C-ring, tile bridge, paint mask, cutout template, and grille — providing everything needed for a clean ceiling tile or drywall installation without additional accessories.
