QI-CPRO4C - Ceiling Pro 4" Deep Metal Back Loudspeaker (White)

Premium 4" Coaxial Ceiling Speaker with Deep Metal Back Can for Enhanced Bass

The Quad Industrial QI-CPRO4C is a high-performance 4-inch coaxial ceiling loudspeaker engineered for commercial spaces that demand superior audio depth and clarity. The "C" variant is distinguished by its deep metal back can, which provides a larger internal acoustic volume. This results in a richer, more controlled low-frequency response (down to 60 Hz) compared to standard or slim-profile models.

Equipped with a 4-inch LF driver and a 0.75-inch silk swivel tweeter, the CPRO4C allows for precise high-frequency adjustment, enabling installers to "aim" the sound toward the primary listening area. With an ultra-wide 130° coverage pattern, it delivers a smooth, even soundstage, making it ideal for high-end retail, hospitality, and corporate boardrooms.

The sleek, bezel-free magnetic grille ensures a modern, minimalist look that sits flush against the ceiling. Designed for professional reliability, it includes a 4-pin Euroblock connector for easy daisy-chaining and an integrated transformer for 70V/100V systems or 8Ω low-impedance use.

Key Features:

• Deep Metal Back Can: Provides an increased acoustic chamber for enhanced bass extension and full fire-rated isolation.

• Silk Swivel Tweeter: 0.75-inch tweeter can be angled for precise directional control of high frequencies.

• Consistent Wide Coverage: Ultra-wide 130° x 130° dispersion ensures fewer dead spots and venue-wide audio consistency.

• Architectural Discreetness: Bezel-free magnetic grille for a clean, professional finish that disappears into the ceiling.

• Versatile Power Taps: Integrated transformer with a convenient tap switch for 70V/100V line systems or 8Ω operation.

• Safe & Secure: Fire-rated metal enclosure with integrated mounting clamps and safety wire rigging point.
