GRS 10PT-8 Woofer

The GRS 10PT-8 is a 10-inch professional paper cone woofer engineered to deliver deep, articulate bass with remarkable efficiency. Designed for audiophiles and professional sound engineers, this driver excels in applications requiring clean, controlled low-frequency reproduction, from high-fidelity home audio systems to stage monitoring and custom subwoofer enclosures. Its robust construction and carefully tuned parameters make it equally suitable for sealed and ported cabinet designs, offering flexibility for a wide range of acoustic projects.

At the heart of the 10PT-8 lies a paper and fibreglass composite cone, chosen for its optimal balance of stiffness and damping, resulting in natural, uncoloured bass. The 8-ohm voice coil, wound with copper wire, ensures stable impedance and reliable thermal handling. With a sensitivity of 93 dB (1m/2.83V), this woofer converts amplifier power into acoustic output with impressive efficiency. The generous 7.8 mm Xmax allows for substantial linear excursion, enabling deep bass extension without distortion. Key Thiele-Small parameters include a Qts of 0.48, Qms of 11.4, and Qes of 0.5, indicating a well-damped driver suited for both sealed and vented alignments. The 1.6 mH voice coil inductance contributes to smooth high-frequency roll-off, while the 7.1-ohm DC resistance ensures compatibility with typical amplifier loads.

Whether you are upgrading a vintage speaker system or building a high-performance subwoofer, the GRS 10PT-8 delivers authoritative, clean bass with professional-grade reliability.
