The GRS 12SW-4HE Subwoofer delivers deep, accurate low-frequency reproduction for discerning audio enthusiasts and professional installers alike. Engineered for high-excursion performance, this 12-inch driver is ideally suited for sealed and ported enclosures in home theatre systems, high-fidelity stereo setups, and custom car audio installations where controlled, articulate bass is paramount. Its robust construction ensures reliable operation even under demanding conditions.

At the heart of the design lies a paper cone and copper voice coil, working in concert to produce a natural, uncoloured bass response with excellent transient speed. The subwoofer’s low total Q factor (Qts 0.43) and generous linear excursion (Xmax 12.5 mm) enable it to move substantial air while maintaining precision. With a sensitivity of 84.5 dB and a 4-ohm impedance, it pairs effectively with moderate amplification. The 8-hole mounting pattern and 279.4 mm cutout diameter simplify installation, while the 16 mm mounting depth allows for flexible enclosure design. Whether for a dedicated home cinema or a competition-grade sound system, the 12SW-4HE offers the performance and build quality expected from GRS.
