Faital Pro 4FE35 4 Ohm (Ω) 4-Inch Professional Woofer
The Faital Pro 4FE35 is a compact professional woofer for speaker designs that need a 4-inch format without giving up broad frequency coverage. Its 4 Ohm impedance, 91 dB sensitivity and steel basket make it a practical choice for building or servicing compact loudspeaker systems.
Compact Fit for Custom Builds
Firstly, with a 100 mm nominal diameter, 91.5 mm baffle cutout and 49.8 mm depth, the 4FE35 is suited to installations where space matters. The 129.85/100.5 mm overall diameter and 115.26 mm bolt circle diameter give enclosure designers the measurements needed to plan the front panel accurately.
Efficient, Broad-Range Output
Moreover, the 91 dB sensitivity allows the woofer to make effective use of amplifier power. Meanwhile, its 90÷20000 Hz frequency range covers a wide portion of the audible spectrum. With 30 W AES power handling and 60 W maximum power handling, it is specified for carefully matched compact speaker designs.
Built for Controlled Movement
Furthermore, a Ferrite Ring magnet, 19 mm voice coil, Kapton former and Copper Cap demodulation form the core assembly. The Half Roll cone surround and 1x constant height waves spider profile manage the moving structure. Also, the 1.1 T flux density is specified for the magnetic circuit.
Clear Design Parameters
The published Thiele and small parameters make enclosure planning more straightforward. Fs is 100 Hz, with Qts of 0.73, Vas of 2.4 dm^3 and Sd of 51.9 cm^2. These figures give builders useful reference points when modelling the woofer in a custom cabinet.
