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.
