GRS 8SW-4HE-8 Subwoofer

The GRS 8SW-4HE-8 is a high-excursion subwoofer engineered to deliver deep, accurate low-frequency reproduction for discerning audio enthusiasts. This 8-inch driver, with a 4-ohm impedance, is ideally suited for use in sealed or ported enclosures within home theatre systems, high-fidelity stereo setups, or custom car audio installations where controlled, impactful bass is essential. Its robust construction ensures reliable performance across a wide range of demanding applications.

Technically, this subwoofer features a treated paper cone paired with a durable rubber surround, which together provide exceptional rigidity and damping for distortion-free sound even at high excursion levels. The maximum linear excursion (Xmax) of 10.8 mm allows for impressive cone movement, while the total Q factor (Qts) of 0.45 indicates excellent alignment for tight, articulate bass. The 2-inch copper voice coil, with a DC resistance of 3.8 ohms and an inductance of 2.7 mH, ensures efficient power handling and thermal stability. With a sensitivity of 85 dB (SPL 1m/2.83V), this driver requires moderate amplifier power to achieve its full potential.

The subwoofer’s 203.2 mm nominal diameter and 181 mm cut-out diameter, secured by eight mounting holes on a 7.8-inch bolt circle, facilitate straightforward installation. Its 116.8 mm mounting depth allows for use in compact enclosures. Combining high-excursion capability with meticulous engineering, the GRS 8SW-4HE-8 is a reliable choice for achieving authoritative low-end performance in any audio project.
