GRS 12PR-8 12" Poly Cone Rubber Surround Woofer

The GRS 12PR-8 is a 12-inch poly cone woofer designed to deliver deep, controlled bass with impressive clarity. Its robust construction and carefully engineered components make it an excellent choice for a wide range of audio applications, from custom loudspeaker builds to upgrading existing cabinets. Whether you are designing a dedicated subwoofer system, a high-fidelity bass mid-bass driver for a two-way design, or a powerful home theatre setup, this driver offers the performance and reliability required for demanding projects.

At the heart of the 12PR-8 is a durable polypropylene cone paired with a long-lasting rubber surround, ensuring consistent performance and longevity. The ferrite magnet and 1.4 mH voice coil inductance contribute to a total Q (Qts) of 1.26, which indicates a well-damped response suitable for sealed or ported enclosures. With a maximum linear excursion (Xmax) of 3.5 mm and a sensitivity of 84 dB (SPL 1m/2.83V), this woofer balances output with control. The 8-hole mounting pattern and 281 mm cutout diameter simplify installation, while the 7.59 ohm DC resistance ensures compatibility with standard amplifiers. Ideal for audiophiles and DIY enthusiasts, the 12PR-8 delivers authoritative bass with precision.
