Faital Pro 3FE26 8 Ohm (Ω), 3-Inch Professional Woofer
The Faital Pro 3FE26 is a compact professional woofer for speaker designs where available space matters. Its 8 Ohm impedance, 90 dB sensitivity and 100÷20000 Hz frequency range give designers clearly defined electrical and acoustic parameters. Meanwhile, the neodymium ring magnet keeps the driver’s format compact.
Compact dimensions for practical builds
Firstly, with an 80 mm (3 in) nominal diameter, 39.7 mm depth and 150 g net weight, the 3FE26 suits compact speaker construction. The 73.6 mm baffle cutout diameter and 92 mm bolt circle diameter provide clear measurements for planning the mounting area before installation.
Defined power and impedance parameters
Moreover, the driver is rated at 20 W AES power handling, with 40 W maximum power handling. Its 8 Ohm nominal impedance and 6.4 Ohm minimum impedance give a straightforward basis for matching the woofer to an amplifier and designing around its stated electrical limits.
Efficient magnetic and mechanical design
A neodymium ring magnet, 1.2 T flux density and steel basket form the core of the driver’s construction. The 19 mm voice coil uses an Al winding with a Kapton former, while the Half Roll cone surround and 1x constant height waves spider profile define its moving assembly.
Parameters for enclosure planning
For more detailed loudspeaker design work, the 3FE26 includes Thiele and Small parameters such as Fs 150 Hz, Qts 0.79, Vas 0.9 dm^3 (0.03 ft^3) and Sd 33 cm^2 (5.12 in^2). These values give builders practical reference points when developing an enclosure around the driver.
