Overview

Tang Band W3-2052SC 3" RBM Neodymium Subwoofer 4 Ohm

Compact Subwoofer, Big Punch 

Don't let its size fool you—the Tang Band W3‑2052SC packs real low-end punch from a 3″ driver. With a substantial 5 mm linear excursion (Xmax), it produces deep and powerful bass in micro‑enclosures. Thanks to its polypropylene cone with Santoprene surround, this driver maintains controlled motion and long-term reliability.

Powering the W3‑2052SC is a precision-engineered neodymium magnet motor system with an overhung design that has been optimized to produce consistent magnetic flux across the large stroke. But what really sets it apart is the dual-surround, dual-diaphragm configuration—no conventional spider here. Instead, compliance is achieved through back-to-back surrounds, maintaining tight linearity even under stress.

Whether you’re building a compact 2‑way bookshelf speaker, a mini subwoofer, or upgrading older systems, the W3‑2052SC adapts beautifully. Optimized for linearity, this woofer produces clean, impactful lows in small systems where space matters most. It fits tight spaces with ease but performs like a driver twice its size.
