GRS 10SMP-8 Bass-midwoofer

The GRS 10SMP-8 Bass-Midwoofer is a meticulously engineered driver designed to deliver deep, articulate bass and a clear, detailed midrange response, making it an exceptional choice for discerning audio enthusiasts and custom speaker builders. This versatile 8-ohm unit combines robust low-frequency extension with musical accuracy, ensuring your projects achieve a natural, immersive soundstage.

Ideal for use in high-fidelity two-way or three-way loudspeaker systems, this woofer excels in both sealed and ported enclosures, offering flexibility for bookshelf, floor-standing, or subwoofer designs. Its balanced performance also suits automotive audio installations where space is at a premium but uncompromising sound quality is required. Whether you are upgrading existing speakers or constructing a bespoke system, the 10SMP-8 provides a solid foundation for rich, controlled bass and smooth midrange reproduction.

Technically, the driver features a 39mm voice coil and a maximum linear excursion (Xmax) of 5mm, supported by a displacement volume (Vd) of 17 litres. With a resonant frequency (Fs) of 29Hz and a total Q factor (Qts) of 0.58, it is well-suited for extended bass response. The 87.5dB sensitivity (1m/2.83V) and 0.46mH voice coil inductance ensure efficient power handling and transient accuracy. The mechanical (Qms: 2.75) and electromagnetic (Qes: 0.73) Q values contribute to controlled damping, while the equivalent volume (Vas: 81 litres) and compliance (Cms: 0.49mm/N) aid enclosure design. The 6.1-ohm DC resistance and five mounting holes simplify integration.

In summary, the GRS 10SMP-8 is a reliable, high-performance bass-midwoofer that brings professional-grade sound to your audio projects, combining technical precision with practical versatility.
