GRS 10SW-4 10" Poly Cone Subwoofer

The GRS 10SW-4 Subwoofer is a robust 10-inch driver engineered to deliver deep, accurate low-frequency reproduction for a wide range of audio applications. Whether you are building a custom home theatre system, upgrading a car audio installation, or designing a dedicated subwoofer enclosure, this unit provides the foundation for powerful, controlled bass. Its versatile performance makes it equally suited to sealed and ported cabinet designs, allowing you to tailor the response to your specific listening environment.

At the heart of the 10SW-4 lies a polypropylene cone, chosen for its excellent stiffness-to-weight ratio, which ensures clean, distortion-free bass even at high excursion levels. The ferrite magnet system, combined with a copper voice coil, generates a sensitivity of 90 dB SPL at 1m/2.83V, enabling efficient power handling. Key technical specifications include a total Q (Qts) of 0.93, a mechanical Q (Qms) of 4.8, and an electrical Q (Qes) of 1.16, indicating a well-damped driver suitable for extended low-end output. With a maximum linear excursion (Xmax) of 8.5 mm and a DC resistance (Re) of 3.7 ohms, this subwoofer is built to handle demanding passages with authority. The steel basket and eight mounting holes ensure secure installation, while the 254 mm nominal diameter fits standard enclosures. For audiophiles and hobbyists seeking reliable, high-quality bass reproduction, the GRS 10SW-4 is a compelling choice.
