FaitalPRO 3FE25-4F Full-range Woofer

The FaitalPRO 3FE25-4F is a 3-inch full-range broadband woofer that delivers remarkably clear and detailed audio from a compact footprint. Designed for high-fidelity applications, this 4-ohm driver excels in scenarios where space is at a premium but sound quality cannot be compromised. It is ideally suited for use in small monitor speakers, portable public address systems, soundbar upgrades, and custom automotive audio installations where a single driver must cover the entire frequency spectrum with coherence and precision.

Technically, the 3FE25-4F features an aluminium voice coil that ensures excellent thermal management and low moving mass, contributing to its high 91 dB sensitivity (1m/2.83V) for efficient power handling and dynamic response. The total Q factor (Qts) of 0.66 indicates a well-damped alignment suitable for both sealed and ported enclosures, while the mechanical Q (Qms) of 4.1 and low voice coil inductance (Le) of 0.07 mH support extended high-frequency extension and transient accuracy. With a maximum linear excursion (Xmax) of 1.83 mm and a DC resistance (Re) of 6.2 ohms, this driver offers controlled bass response and reliable performance. The 76.2 mm nominal diameter, 73.6 mm cut-out, and 92 mm bolt circle with four mounting holes simplify integration into existing designs. At just 54.5 mm depth, it fits easily into shallow cabinets, making it a versatile choice for engineers and hobbyists seeking professional-grade full-range sound.
