GRS 10S-8 Full-range Woofer

The GRS 10S-8 4" Full-Range Driver offers a compelling solution for those seeking clear, coherent audio from a compact form factor. As a broadband driver, it is engineered to reproduce a wide frequency spectrum without the need for a separate tweeter, making it an excellent choice for small-scale speaker designs, portable audio projects, or as a direct replacement in existing systems where space is at a premium. Its versatility extends to use in desktop monitors, surround sound channels, or custom installations where a balanced, full-range sound is desired.

Technically, this driver features an 8-ohm impedance and a sensitivity of 87 dB SPL at 1 metre with 2.83V input, ensuring efficient power handling. The total Q factor (Qts) of 1.65, combined with a mechanical Q (Qms) of 7.68 and an electromagnetic Q (Qes) of 2.1, indicates a well-damped response suitable for sealed or ported enclosures. With a maximum linear excursion (Xmax) of 1.5 mm and a voice coil inductance (Le) of just 0.21 mH, it delivers controlled bass and clear midrange. The driver’s nominal diameter is 101.6 mm, with a mounting depth of 39.7 mm and four fixing holes for secure installation. The DC resistance (Re) measures 7.2 ohms, ensuring compatibility with typical amplifier loads. This full-range driver is a practical choice for achieving high-quality audio in compact, cost-effective designs.
