Overview
The Celto Pro HFDN754 is a premium neodymium high-frequency compression driver engineered for demanding professional sound reinforcement and high-end acoustic installations. Featuring a 1.
4-inch (36 mm) throat exit and a 3-inch (75 mm) voice coil, it utilizes an AlTiN (Aluminium Titanium Nitride) dome combined with a DuPont PI surround to deliver exceptional linearity and transient response. Operating across a wide frequency range of 0.6 kHz to 22 kHz, it boasts an impressive sensitivity of 110 dB (1W/1m). Distortion is minimized through a CNC-machined ZAMAC annular phase plug and an integrated copper shorting cap. With a 16 Ohm nominal impedance, the HFDN754 handles up to 150 W RMS (AES) above 1200 Hz (100 W RMS above 600 Hz), making it an ideal choice for high-performance touring systems, fixed installations, and portable PA applications.
