HH Audio, Aptur APT-C4 | 4" Ceiling Speaker - 100V & 8 Ohms, White or Black
DETAILS
The HH Audio APT-C4 is a high-performance 4-inch coaxial ceiling speaker, designed to deliver clear and balanced audio for commercial, corporate, hospitality, and educational environments.
Featuring a Celestion 4-inch coaxial driver with a 1.25-inch LF voice coil and a 0.75-inch HF voice coil, the APT-C4 ensures natural sound reproduction with uniform coverage across the listening area. A custom horn flare profile further enhances clarity, making it ideal for both background music and speech applications.
With a sensitivity of 87dB (1W/1M) and a 75W AES power rating, the APT-C4 achieves a maximum SPL of 105dB, ensuring excellent audio performance even in larger spaces. Its frequency response of 90Hz to 20kHz provides a well-rounded sound profile, and for applications requiring extended bass, it pairs seamlessly with the APT-C8S ceiling subwoofer or the APT-W8S surface-mount subwoofer. The built-in multi-tap transformer allows for flexible operation in both low-impedance (Lo-Z) and 70V/100V line systems, making it suitable for a wide range of installations.
Designed for ease of installation and aesthetic integration, the APT-C4 features a magnetic edge-to-edge grille with a removable HH logo, reversible dog ear mounts to accommodate various ceiling thicknesses, and a powder-coated steel back can with an integrated safety tether eyelet. It is available in white as standard, with an optional black grille for discreet installations in darker environments.
