GRS 10SMP-4 Bass-midwoofer

The GRS 10SMP-4 Bass-midwoofer is a meticulously engineered 10-inch driver designed to deliver a compelling blend of deep, articulate bass and clear, detailed midrange response. Whether you are constructing a high-fidelity two-way bookshelf speaker, a dedicated subwoofer system, or a multi-way home theatre setup, this versatile unit excels as both a bass and mid-bass transducer. Its well-balanced parameters make it particularly suitable for sealed or ported enclosures, where it can reproduce low frequencies with authority and precision.

Technically, the driver boasts a low resonance frequency of 28 Hz and a total Q factor (Qts) of 0.51, which together enable excellent low-frequency extension and controlled damping. The 4-ohm impedance and 90 dB sensitivity ensure efficient power handling and solid output from modest amplification. With a maximum linear excursion (Xmax) of 5 mm and a displacement volume (Vd) of 17, it can move significant air for impactful bass. The 39 mm voice coil and 3.8 ohm DC resistance contribute to robust thermal management and reliable performance. The mechanical (Qms 2.72) and electrical (Qes 0.63) Q factors are carefully balanced to minimise distortion while maintaining transient speed. This bass-midwoofer is an outstanding choice for any enthusiast seeking a high-quality, long-lasting driver that brings music to life with depth and clarity.
