Faital Pro HF140 8 Ohm High-Frequency Driver
The Faital Pro HF140 is a high-frequency driver for speaker-building projects that need a defined, efficient top end. Its titanium diaphragm, neodymium magnet and 1.4-inch throat combine with clearly specified power and crossover figures. Meanwhile, the 8 Ohm design makes its electrical requirements easy to identify during system planning.
Efficient High-Frequency Output
Firstly, with 109 dB sensitivity, the driver can produce strong acoustic output from a given amplifier input. That makes sensitivity an important consideration when matching the high-frequency section with the rest of a speaker system. The titanium diaphragm and dome shape complete a focused construction aimed at high-frequency reproduction.
Power Figures for System Design
Moreover, the driver is rated for 70 W AES power above 0.9 kHz, with 140 W maximum power above the same point. Additional ratings are provided above 0.65 kHz, giving builders clear figures to consider when selecting amplification and setting the system’s crossover design. The 0.9 kHz minimum crossover frequency remains an important planning point.
Practical Mechanical Construction
A neodymium slug crown magnet, annular phase plug and 7° conical exit angle define the driver’s construction. The 35.6 mm throat, 130.5 mm overall diameter and 62 mm depth provide useful reference points when planning mounting hardware or an enclosure. Four M6 mounting holes are arranged on a 102 mm diameter.
Built for Detailed Planning
The listed frequency range is 0.5÷18 kHz, while the 8 Ohm nominal impedance and 6.3 Ohm minimum impedance clarify the electrical load. A 74 mm aluminium voice coil uses a Kapton former, and the 2.9 kg net weight gives builders another practical figure for handling and installation planning.
