GRS 5SMP-8 Bass-midwoofer

The GRS 5SMP-8 Bass-Midwoofer is a meticulously engineered 8-inch driver designed to deliver accurate and controlled bass and midrange reproduction. Ideal for audiophiles and DIY enthusiasts, this versatile unit excels in both sealed and ported enclosures, making it a superb choice for high-fidelity two-way speaker systems, compact subwoofer designs, or as a dedicated mid-bass driver in multi-way setups. Its balanced performance ensures seamless integration with tweeters and subwoofers, offering a cohesive soundstage for music and home cinema applications.

Technically, the 5SMP-8 boasts a total Q factor (Qts) of 0.44, providing a well-damped response that suits a variety of cabinet alignments. With a sensitivity of 86.4 dB (1m/2.83V) and an 8-ohm impedance, it pairs efficiently with moderate amplification. The 26mm voice coil and 2mm Xmax ensure linear excursion, while a moving mass of 12g and a resonance frequency of 55 Hz contribute to articulate low-frequency output. The mechanical (Qms: 3.26) and electrical (Qes: 0.51) Q factors further refine transient response. Whether for a refined bookshelf speaker or a custom project, this driver delivers precise, musical performance in a compact footprint.
