T2-2181SA 2" Subwoofer Module | 175 x 70 mm

The Tang Band T2-2181SA 2" Subwoofer Module is a compact yet powerful solution for adding genuine low-frequency depth to space-constrained audio systems. Measuring just 210 x 71 mm with a mounting depth of only 40 mm, this slim subwoofer module is purpose-built for applications where traditional larger drivers simply cannot fit. Its thoughtful engineering makes it an ideal choice for upgrading desktop speakers, soundbars, portable Bluetooth enclosures, or custom car audio installations where every millimetre counts.

At the heart of this module lies a passive radiator design, which works in concert with the active driver to extend bass response without requiring a large, ported enclosure. The neodymium magnet ensures high efficiency and a strong motor force despite the compact footprint, while the polypropylene composite cone and rubber surround deliver clean, controlled excursion. With a nominal impedance of 4 ohms, a maximum power handling of 20 watts, and a resonance frequency of 58 Hz, this subwoofer is engineered to produce tight, articulate bass that complements rather than overwhelms the midrange. The 25.4 mm voice coil and rubber frame further enhance durability and linearity. Whether you are designing a minimalist hi-fi system or a discreet automotive upgrade, the T2-2181SA offers a refined low-end foundation in a remarkably shallow package.
