W3-871SC 3" Full-range Woofer

The Tang Band W3-871SC is a meticulously engineered 3-inch full-range woofer that brings clarity and natural warmth to compact audio systems. As a broadband driver, it excels at reproducing a wide frequency spectrum from a single speaker, making it an ideal choice for DIY speaker builders, desktop monitors, and small-scale hi-fi installations where space is at a premium. Its balanced performance also suits multimedia speakers, portable audio projects, and upgrade replacements for existing compact enclosures.

At the heart of this driver lies a paper cone, chosen for its lightweight yet rigid properties that deliver articulate midrange and smooth high-frequency extension. The ferrite magnet assembly ensures efficient motor force, while the 0.5mm linear excursion (Xmax) allows controlled bass response within its size class. With a total Q factor (Qts) of 0.59, the W3-871SC is well-suited for sealed or ported enclosures, offering a harmonious blend of transient speed and low-end presence. The 6.6-ohm DC resistance and 87dB sensitivity (2.83V/1m) make it compatible with a wide range of amplifiers. Mechanically, the 71.5mm cutout diameter and four mounting holes simplify installation, while the 60mm depth accommodates slim cabinet designs. Whether for a near-field monitor or a compact bookshelf speaker, this Tang Band driver delivers authentic, full-range sound with impressive coherence.
