FaitalPRO 4FE35-8F Full-range Woofer

The FaitalPRO 4FE35-8F is a 4-inch full-range woofer engineered to deliver clear, coherent sound across the entire audio spectrum from a single, compact driver. This 8-ohm broadband transducer is ideally suited for high-fidelity loudspeaker systems where space is at a premium, including studio monitors, desktop speakers, and portable public address enclosures. Its full-range capability also makes it an excellent choice for soundbar upgrades and custom audio projects requiring a balanced, natural sound without the complexity of multi-way crossover networks.

Technically, this driver features an aluminium voice coil for excellent heat dissipation and low moving mass, resulting in crisp transient response and extended high-frequency extension. With a sensitivity of 91 dB SPL (1m/2.83V), it offers efficient power handling and dynamic output from modest amplifier power. The total Q factor (Qts) of 0.83 indicates a well-damped alignment suitable for sealed or small vented enclosures, while the maximum linear excursion (Xmax) of 2.73 mm ensures controlled bass reproduction. The robust chassis has a nominal diameter of 101.6 mm, with a cut-out diameter of 91.5 mm and a four-hole fixing pattern on a 115.26 mm bolt circle, simplifying integration into existing designs. Combining efficiency, wide bandwidth, and compact dimensions, the FaitalPRO 4FE35-8F is a versatile foundation for premium full-range loudspeaker projects.
