Overview
The Celto Pro HFD754 is a high-performance high-frequency (HF) compression driver engineered for professional sound reinforcement and demanding acoustic installations. Featuring a 1.
4-inch (36 mm) throat exit and a 3-inch (75 mm) voice coil, this premium transducer delivers an exceptional sensitivity of 110 dB (1W/1m). Its advanced AlTiN (Aluminium Titanium Nitride) dome combined with a DuPont PI surround ensures highly stable, low-distortion high-frequency reproduction. With a power handling of 100 W RMS above 600 Hz and 150 W RMS above 1200 Hz, it covers a wide frequency range from 0.6 kHz to 22 kHz. The integration of a CNC-machined ZAMAC annular phase plug and a shorting copper cap minimizes inductance while maximizing acoustic efficiency. Powered by a high-flux 1.85 T ferrite magnet assembly and utilizing a 240°C thermal class PI CCAR winding, the HFD754 guarantees outstanding thermal stability and reliability under continuous, high-power operation.
