GRS 8SMP-8 Bass-midwoofer

The GRS 8SMP-8 Bass-midwoofer is a meticulously engineered 8-inch driver designed to deliver a compelling blend of tight, controlled bass and articulate midrange response. Ideal for audiophiles and DIY enthusiasts, this woofer excels in two-way or multi-way speaker systems, where it can handle both low-frequency foundations and the critical lower midrange with equal authority. Its performance characteristics make it particularly well-suited for compact bookshelf designs, floor-standing towers, or even as a dedicated mid-bass unit in more complex configurations.

Technically, the 8SMP-8 is built around a robust motor system that achieves a linear excursion of 5.5mm, ensuring dynamic and distortion-free output even at higher volumes. With a sensitivity of 89.5dB (1m/2.83V) and a total Q factor (Qts) of 0.46, it is well-suited for both sealed and ported enclosures, offering flexibility in cabinet design. The 8-ohm impedance and 5.8-ohm DC resistance pair with a 39mm voice coil and an inductance of 0.41mH for controlled transient response. A resonant frequency of 41Hz and an equivalent volume (Vas) of 32.5 litres further define its low-end capabilities. Whether you are upgrading an existing system or building from scratch, this driver provides the precision and authority needed for a truly engaging listening experience.
