Faital Pro 4FE32 16 Ohm (Ω), 4-Inch Professional Woofer
The Faital Pro 4FE32 is a compact woofer for planned speaker builds where physical size, electrical load and measured driver data matter. Its neodymium ring magnet, steel basket and broad frequency range give enclosure designers a clear starting point for developing a focused system. Specifically one around a 4-inch format, that is.
Compact Installation Planning
At 100 mm (4 in) nominal diameter, the 4FE32 suits builds where available space needs careful attention. The 91.5 mm baffle cutout, 49.8 mm depth and 115.26 mm bolt circle diameter make the key mounting dimensions easy to check before fabrication. Meanwhile, the 270 g net weight keeps the driver straightforward to handle.
Measured Output and Power Data
Moreover, the driver combines 91 dB sensitivity with 30 W AES power handling and 60 W maximum power handling. These figures give system designers useful reference points when matching amplification and setting expectations for the finished speaker, without replacing the enclosure and crossover work needed for a complete design.
Construction for Driver Development
A Neodymium Ring magnet sits in a steel basket, with an Al voice-coil winding on a Kapton former. The Half Roll cone surround and 1x constant height waves spider profile are specified alongside the magnetic data, giving builders the construction details needed when assessing the driver for a particular project.
Reference Data for Modelling
The Thiele and Small parameters include Fs, Re, Qes, Qms, Qts, Vas and Sd, while Xmax and Xdamage describe excursion reference points. Used during modelling, these values help builders assess how the driver may behave in a proposed enclosure; the final result still depends on the complete design.
