GRS 8PF-8 8" Paper Cone Foam Surround Woofer

The GRS 8PF-8 is an 8-inch paper cone woofer engineered to deliver a clean, natural balance of bass and midrange frequencies, making it an excellent choice for audio enthusiasts seeking authentic sound reproduction. Its foam surround ensures smooth, controlled cone movement, contributing to the driver's articulate and uncoloured response.

This versatile woofer is ideally suited for use as a dedicated bass or mid-bass driver in two-way or three-way loudspeaker systems. It also performs admirably as a subwoofer in compact designs, where its extended linear excursion and efficient motor structure allow it to produce satisfying low-end output without sacrificing clarity in the critical midrange.

Technically, the 8PF-8 features a ferrite magnet motor and a 7.59 ohm DC resistance voice coil with an inductance of 1.11 mH, ensuring stable electrical behaviour. Its total Q factor (Qts) of 0.93, combined with a mechanical Q (Qms) of 4.58 and an electromagnetic Q (Qes) of 1.17, indicates a well-damped driver suitable for sealed or ported enclosures. With a maximum linear excursion (Xmax) of 3 mm and a sensitivity of 87 dB SPL (1m/2.83V), it offers efficient power handling. The woofer's nominal diameter is 203.2 mm, with a mounting cut-out of 185.9 mm and a depth of 87.4 mm, secured by four fixing holes.

In summary, the GRS 8PF-8 provides a reliable foundation for building high-fidelity loudspeakers that demand natural, articulate bass and midrange performance.
