SB Acoustics Satori WO34HC-4 13.5″ Honeycomb Cone Woofer

With its 585 cm² effective piston area and a 75.6 mm voice coil diameter, the Satori WO34HC-4 stands out among woofers for its ability to reproduce deep, clean bass with minimal distortion. The unique honeycomb cone structure, reinforced by black fiberglass skin layers, ensures both rigidity and low mass, resulting in fast transient response and reduced cone breakup. This makes it a perfect fit for high-end home audio systems where musical accuracy and dynamic impact are paramount.

The advanced motor system features a large vented magnet with an undercut pole piece and dual shorting rings, effectively lowering inductance and minimizing non-linear distortion. This thoughtful design contributes to a smooth and controlled frequency response, as demonstrated by its on- and off-axis response curves. The vented cast aluminum chassis not only provides a sturdy foundation but also promotes efficient airflow, reducing compression and keeping the coil cool during extended high-power use.

For builders and DIY enthusiasts, the Satori WO34HC-4 offers exceptional flexibility. Its linear symmetric suspension and soft rubber surround support a maximum linear coil travel of 16.6 mm (peak-to-peak), which allows for deep bass extension without sacrificing control. The 3-inch copper voice coil wound on a non-conductive fiberglass former ensures reliable performance even under heavy load, while the long-life silver lead wires provide durability for years of trouble-free operation. These features make it an excellent choice for custom DIY speaker kit projects and professional installations alike.

Integrating the WO34HC-4 into your setup is straightforward, thanks to its 4-ohm nominal impedance and impressive 200 W rated power handling. Whether used as a dedicated subwoofer in a multi-way system or as a high-performance bass driver in a large floor-standing design, this woofer is compatible with a broad range of amplifiers and cables. Its exceptional sensitivity of 92.5 dB (2.83V/1m) ensures efficient operation even with modestly powered amplification, making it a standout choice for those seeking uncompromising bass performance and reliability in their audio systems.
