QI-CPRO4A - Ceiling Pro 4" Discreet Loudspeaker (White)

Ultra-Slim 4" Ceiling Loudspeaker for Shallow Voids & Discreet Audio

The Quad Industrial QI-CPRO4A is a premium 4-inch coaxial ceiling loudspeaker specifically designed for installations with limited mounting depth. Part of the "Discreet" series, the CPRO4A features an ultra-low-profile design that allows it to be installed in shallow ceiling voids where standard loudspeakers simply cannot fit.

Despite its compact depth, the CPRO4A delivers high-fidelity sound via a 4-inch coaxial driver and a 0.75-inch silk dome tweeter. With a wide 120° coverage pattern, it provides smooth and consistent audio distribution, making it the ideal choice for high-end retail, hospitality, and corporate environments.

The speaker is finished with a bezel-free magnetic grille that sits flush against the ceiling for a clean, architectural look. For ease of installation, it includes a quick-fit 4-pin Euroblock connector and a multi-tap transformer for seamless integration into 70V/100V or 8Ω systems.
