W2-2040S 2" Poly Cone RBM Micro Subwoofer 4 Ohm

The Tang Band W2-2040S is a 2-inch poly cone micro subwoofer that redefines expectations for compact bass reproduction. Despite its diminutive footprint, this 4-ohm driver delivers deep, controlled low frequencies that belie its size, making it an exceptional choice for space-constrained audio projects. Ideal for desktop sound systems, portable Bluetooth speakers, small home theatre setups, or custom car audio installations, this subwoofer brings a surprising weight and presence to any build where traditional larger drivers simply cannot fit.

Engineered with a polypropylene composite cone and a robust motor assembly, the W2-2040S achieves a remarkably low total Q factor of 0.26, indicating tight, accurate bass response suited to sealed enclosures. Its maximum linear excursion (Xmax) of 5.3mm allows for significant air displacement, while the copper voice coil wire ensures efficient power handling and thermal stability. The mechanical Q (Qms) of 5.21 and electrical Q (Qes) of 0.28 further contribute to its controlled damping characteristics. With a sensitivity of 79 dB SPL at 1m/2.83V and a DC resistance of 3.5 ohms, this micro subwoofer integrates seamlessly into compact designs. The 55.9mm cutout diameter and 76.2mm screw circle facilitate straightforward mounting, while the 54.6mm depth accommodates slim enclosures. For audiophiles and DIY enthusiasts seeking authoritative low-end extension without sacrificing space, the Tang Band W2-2040S delivers a compelling solution.
