Faital Pro 4FE35 8 Ohm (Ω), 4-Inch Professional Woofer
The Faital Pro 4FE35 is a compact 4-inch professional woofer for loudspeaker projects where accurate fit and clearly defined driver data matter. Its steel basket, Ferrite Ring magnet and modest mounting depth keep the physical design manageable. Meanwhile, the supplied Thiele and small parameters give enclosure planning a solid technical starting point.
Compact Fit for Cabinet Projects
Firstly, at 100 mm nominal diameter and 58.3 mm deep, the driver suits designs where available cabinet space needs careful attention. The 91.5 mm baffle cutout and 115.26 mm bolt circle diameter make the mounting layout easier to map out before construction, while the 570 g net weight keeps handling straightforward.
Clear Electrical and Acoustic Reference Points
The 8 Ohm nominal impedance, 7.2 Ohm minimum impedance and 91 dB sensitivity give system planners useful figures when matching the woofer to the rest of a loudspeaker design. Its listed 90÷20000 Hz frequency range also shows the broad operating span specified for this driver.
Built for Controlled Driver Movement
A steel basket supports the driver structure, while the Ferrite Ring magnet, Copper Cap demodulation, Half Roll cone surround and 1x constant height waves spider profile define its construction. The 19 mm voice coil uses an Al winding on a Kapton former, with the listed assembly dimensions available for closer enclosure analysis.
Parameters for More Informed Enclosure Work
Fs, Vas, Qes, Qms, Qts, Sd and the other listed Thiele and small parameters help with cabinet calculations and driver assessment. Values such as 2.4 dm^3 Vas, 2.73 mm Xmax and 6.8 mm Xdamage give a more complete picture of the woofer’s mechanical limits without replacing careful design work.
