The Tang Band T1-2121SD Speaker Module is a compact, high-performance audio solution designed for applications where space is at a premium. Measuring just 5-7/16 by 2-3/16 inches, this slim module is ideal for use in custom installations, portable speakers, multimedia systems, or any project requiring a discreet yet capable sound source. Its integrated design simplifies mounting and wiring, making it a convenient choice for both DIY enthusiasts and professional integrators.

At the heart of this module lies a passive radiator configuration, which significantly enhances low-frequency output despite the unit’s shallow 25.4 mm depth. The aluminium cone diaphragm ensures rigidity and low distortion, while the neodymium magnet provides efficient motor force for clear, dynamic sound. A 28 mm copper voice coil handles up to 12 watts of power, and the polymer basket with rubber surround contributes to durability and controlled cone movement. With an impedance of 4 ohms and a sensitivity of 79 dB (SPL at 1m/2.83V), the module is easy to drive and suitable for a variety of amplifier pairings.

The T1-2121SD combines thoughtful engineering with a space-saving footprint, delivering surprising bass extension and clean midrange in a package that fits effortlessly into tight enclosures. Whether for a bespoke audio project or a commercial product, this Tang Band module offers reliable performance and straightforward integration.
