Overview

Tang Band W1-1070SI 1" Full-Range Speaker Module 4 Ohm 2" x 2"

Full-Range Performance in a Small Package 

The Tang Band W1-1070SI brings big performance to small spaces in a self-contained, ready-to-use format. Using Tang Band’s highly regarded W1-1070SH 1" full-range driver, this sealed module delivers detailed mids and highs with a compact footprint just over 2" square and 1.25" deep. By providing its own enclosure, the W1-1070SI makes it easy to add high-quality sound to custom projects without the challenge of designing or building a tiny enclosure.

Driving the W1-1070SI is the aluminum-cone W1-1070SH full range driver, supported by a Santoprene surround and neodymium motor for smooth, controlled performance across its range. The rigid cone maintains pistonic motion at all output levels, while low inductance ensures clean, extended treble. With frequency response reaching from ~200 Hz up to 20 kHz, this tiny module covers the critical midrange and highs with surprising accuracy and output capability.

Thanks to its slim dimensions, the W1-1070SI can be mounted almost anywhere. It’s an excellent choice for desktop speaker arrays, slim soundbars, portable audio builds, or embedded systems where space is at a premium. Since the enclosure is already integrated, installation is as simple as mounting the module and wiring it in.

For designers and DIY builders who want full-range performance without the hassle of cabinet design, the Tang Band W1-1070SI is the perfect solution. Compact, versatile, and engineered around a proven Tang Band driver, this module makes it easy to bring clear, detailed sound to projects where size and simplicity matter most.
