Faital Pro FD375 8 Ohm (Ω), 37mm High-Frequency Driver
Faital Pro FD375 is a high-frequency driver for speaker builds that need focused, efficient HF output. Its 107 dB sensitivity, 8 Ohm nominal impedance and 40° dispersion angle give designers clear reference points. Meanwhile, the annular diaphragm and ferrite ring magnet define a compact, purpose-built driver format.
Efficient High-Frequency Output
The 107 dB sensitivity rating indicates strong output at the specified measurement level, making the FD375 a practical choice when the HF section needs to keep pace within a speaker design. Its 35 W AES power handling and 70 W maximum power handling set clear power figures for system planning.
Focused Coverage for Speaker Design
A 40° dispersion angle gives the high-frequency section a defined coverage pattern rather than broad, uncontrolled spread. The stated 2.6 kHz minimum crossover frequency and 2.6÷20 kHz frequency range provide useful boundaries when selecting the driver’s place within a compatible crossover and enclosure design.
Purpose-Built Driver Construction
The 37 mm voice coil uses Al winding material and a Kapton former, while the Ketone Polymer diaphragm has an annular shape. An annular phase plug and 1.5 T flux density from the Ferrite Ring magnet complete the driver’s focused construction for high-frequency speaker applications.
Practical Fit and Installation Planning
With a 107 mm bolt circle diameter, 91 mm baffle cutout diameter and 79 mm depth, the FD375 is straightforward to assess against a cabinet layout before installation. Its 1.24 kg net weight and 115.2/102 mm overall diameter also help with physical planning around the baffle.
