GRS 10SW-4HE Subwoofer

The GRS 10SW-4HE 10-inch High Excursion Subwoofer delivers authoritative, deep bass that transforms any audio system into a truly immersive listening experience. Designed for audiophiles and DIY enthusiasts alike, this 4-ohm subwoofer excels in sealed and ported enclosures, making it ideal for home theatre setups, high-fidelity stereo systems, or custom car audio installations where accurate low-frequency reproduction is paramount. Whether you are building a dedicated subwoofer cabinet or upgrading an existing design, this driver provides the foundation for powerful, distortion-free sound.

Engineered for performance, the subwoofer features a treated paper cone that combines lightweight responsiveness with exceptional rigidity, ensuring clean transient response and minimal cone breakup. The copper voice coil offers reliable thermal management and low DC resistance (3.8 ohms), while the generous 11 mm linear excursion (Xmax) allows for impressive air displacement without sacrificing control. With a total Q factor (Qts) of 0.5 and a mechanical Q (Qms) of 4, the driver is well-suited for both sealed and vented alignments, offering flexibility in enclosure design. The 254 mm nominal diameter and 233.2 mm cut-out diameter simplify installation, and the eight mounting holes ensure a secure fit. Rated sensitivity is 87.5 dB (1m/2.83V), and the 3 mH voice coil inductance contributes to smooth frequency extension. Finished in a robust frame with a depth of 130.8 mm, this subwoofer is a reliable choice for demanding low-frequency applications.
