Faital Pro HF111 8 Ohm (Ω) 1-Inch High-Frequency Driver
The Faital Pro HF111 8 Ohm is a compact 1-inch high-frequency driver built around a dome diaphragm, annular phase plug and ferrite ring magnet. Its defined impedance, power-handling figures and broad high-frequency range give speaker designers clear technical points for assessing the driver within a suitable system.
High-Frequency Coverage
Firstly, the specified 2÷20 kHz frequency range covers the high-frequency band. Meanwhile, the 2 kHz minimum crossover frequency identifies the lower limit for crossover planning. A 107 dB sensitivity rating at 1W/1m describes the driver’s output level under the stated measurement conditions.
Defined Driver Construction
Moreover, a Ketone Polymer dome diaphragm works with an annular phase plug design, a 37 mm voice coil and Kapton former. The 18° Conical exit angle is also specified. Consequently, giving the HF111 a clearly documented mechanical and acoustic configuration rather than an undefined replacement part.
Power and Electrical Details
Nominal impedance is 8 Ohm, with a 6.6 Ohm minimum impedance and 5.5 Ohm Re value. The driver is rated for 40 W AES power handling and 80 W maximum power handling, giving installers the core electrical and power figures needed when checking system requirements.
Compact Physical Format
The 25.4 mm (1 in) throat, 90 mm overall diameter and 47 mm depth describe a compact form factor. Mounting-hole spacing is specified as 76 mm through the 180° mounting holes diameter, while the 1.3 kg net weight rounds out the physical planning details.
