GRS 10PR-8 10" Poly Cone Rubber Surround Woofer

The GRS 10PR-8 is a 10-inch poly cone woofer engineered to deliver deep, controlled bass and articulate mid-bass response for a variety of audio applications. Its robust construction makes it an ideal choice for DIY speaker builders, replacement drivers in existing cabinets, or custom subwoofer designs where reliable low-frequency performance is essential. Whether you are crafting a dedicated home theatre subwoofer, a high-fidelity stereo system, or a portable PA enclosure, this driver provides a solid foundation for projects requiring accurate bass reproduction.

At the heart of the 10PR-8 lies a polypropylene cone paired with a durable rubber surround, ensuring long-term stability and consistent performance even under demanding conditions. The ferrite magnet assembly drives a voice coil with a DC resistance of 7.58 ohms, while key Thiele-Small parameters—including a Qts of 1.14, Qms of 4.8, and Qes of 1.5—indicate a design suited for sealed or large vented enclosures. With an SPL of 85 dB (2.83V/1m) and a maximum linear excursion (Xmax) of 3 mm, this woofer balances efficiency with controlled cone movement. The 254 mm nominal diameter and 104.8 mm mounting depth, along with a 235 mm cutout diameter and four fixing holes, simplify integration into standard baffles.

This GRS woofer offers a dependable solution for achieving authoritative bass and clear mid-bass in your next audio project.
