W1-2121S Aluminum Full Range Neodymium Driver

The Tang Band W1-2121S is a compact yet remarkably capable aluminium full-range neodymium driver, designed to deliver clear and detailed audio across the frequency spectrum. Despite its small footprint, this 46 mm driver punches well above its weight, making it an ideal choice for space-constrained applications where sound quality cannot be compromised. Whether you are building a miniature bookshelf speaker, a portable Bluetooth enclosure, or a high-fidelity desktop monitor, the W1-2121S offers a versatile solution that brings lifelike reproduction to any compact audio project.

Engineered with an aluminium cone and a neodymium magnet structure, this driver achieves an efficient balance of low mass and high magnetic flux. The copper voice coil ensures low DC resistance (Re) of 3.5 ohms and minimal inductance (Le) of just 0.07 mH, contributing to excellent transient response. With a total Q factor (Qts) of 0.35, it is well-suited for sealed or small ported enclosures, offering controlled bass extension and smooth midrange clarity. The maximum linear excursion (Xmax) of 2.3 mm allows for respectable output levels, while the mechanical (Qms) and electrical (Qes) Q values of 1.33 and 0.47 respectively indicate a well-damped, accurate driver.

This Tang Band driver is a superb choice for audiophiles and DIY enthusiasts seeking premium performance in a miniature form factor. Its robust construction and thoughtful engineering ensure reliable, high-quality sound for years to come.
