APT-C4

The APT-C4 ceiling speaker brings decades of British design and engineering to installation audio. The APT-C4 harnesses a 4-inch Celestion coaxial driver, with a 1.25-inch LF voice coil and a 0.75-inch HF voice coil, enabling crystal-clear, well-balanced sound reproduction. The custom horn flare profile enhances audio clarity and provides well balanced, uniform sound throughout the coverage area.

The APT-C4 has a sensitivity of 87dB (1W/1M) and a 75W AES power rating, yielding a maximum SPL of 105dB SPL. Its frequency response of 90Hz to 20kHz ensures beautifully balanced audio, making it an excellent standalone solution or the perfect companion to the APT-C8S ceiling subwoofer or the APT-W8S surface-mount subwoofer for deeper bass extension.

The APT-C4 features a built-in multi-tap transformer suitable for use in both low-impedance (Lo-Z) and 100V/70V line applications.

Every detail of the APT-C4 is meticulously crafted to strike a perfect balance between aesthetic, acoustic, and mechanical design. Key features include:

• Magnetic edge-to-edge grille with a removable HH logo for seamless integration into any space.
• Reversible dog ear mounts, accommodating ceilings of various thicknesses.
• Powder-coated steel back can with an integrated safety tether eyelet for added security.
• Optional black grille for discreet installations in darker environments.

Whether in hospitality, corporate, commercial or educational settings, the APT-C4 ceiling speaker combines sophisticated engineering with elegant design, delivering uncompromising audio quality and reliability.
