Overview
The Celto Pro HFDN44/DC3 is a flagship high-frequency compression driver engineered for the most demanding acoustic applications. Featuring a 1-inch (25.
4 mm) throat diameter, it combines a Diamond Carbon dome with a DuPont PI surround to deliver distortion-free, ultra-clear high frequencies extending up to 25 kHz. Powered by a 1.7-inch (44 mm) CCAR voice coil with 240°C thermal class PI winding and a high-grade Neodymium ring magnet, it achieves exceptional power handling (80 W RMS above 1600 Hz) and an outstanding sensitivity of 108.5 dB (1W/1m). The integration of a CNC-machined ZAMAC annular phase plug and a shorting copper cap minimizes inductance, ensuring maximum high-frequency detail. It represents an ideal engineering solution for professional sound reinforcement, touring systems, and premium fixed installations.
