GRS 18PT-8 Woofer

The GRS 18PT-8 is a formidable 18-inch professional woofer engineered to deliver deep, authoritative bass with exceptional clarity. Designed for high-performance audio systems, this driver excels in applications such as live sound reinforcement, fixed installation subwoofers, and high-fidelity home theatre setups where controlled, low-frequency extension is paramount. Its robust construction makes it equally suitable for bass guitar cabinets and custom PA systems requiring reliable, high-output performance.

At the heart of this woofer lies a 3-inch copper voice coil, wound on a former that handles high thermal loads with ease, ensuring consistent operation during demanding passages. The paper cone, reinforced with fibreglass, provides an optimal balance of stiffness and damping, contributing to a natural, uncoloured bass response. With an Xmax of 7.8mm, the 18PT-8 achieves significant linear excursion, producing high SPL levels while maintaining low distortion. The motor system is carefully tuned, featuring a Qts of 0.54 and a sensitivity of 93dB (2.83V/1m), allowing it to work effectively in both sealed and ported enclosures. The 8-ohm impedance simplifies multi-driver configurations, while the 422.9mm cutout diameter and 8-hole mounting pattern ensure straightforward installation. Whether for touring sound or permanent installations, this woofer delivers the punch and depth that professionals demand.
