GRS 6SMP-8 Bass-midwoofer

The GRS 6SMP-8 Bass-midwoofer is a meticulously engineered 8-ohm driver designed to deliver accurate and articulate bass and midrange reproduction in high-fidelity loudspeaker systems. Whether you are constructing a dedicated two-way bookshelf speaker, a centre channel, or a compact subwoofer-satellite combination, this versatile unit excels in both sealed and ported enclosures, offering the flexibility to tailor the low-frequency response to your specific acoustic preferences.

With a total Q factor (Qts) of 0.45, this driver provides a controlled and tight response, ensuring that bass notes remain punchy and well-defined without becoming boomy or overbearing. The 5 mm of maximum linear excursion (Xmax) allows for substantial cone movement, enabling dynamic playback at higher volumes while maintaining low distortion. A sensitivity of 87.7 dB (SPL at 1m/2.83V) ensures efficient power handling, making it compatible with a wide range of amplifiers. The 39 mm voice coil and a DC resistance of 6.1 ohms contribute to robust thermal management and reliable long-term performance. The resonance frequency of 47 Hz and an equivalent volume (Vas) of 14.5 litres provide clear guidance for enclosure design, while the mechanical (Qms: 2.7) and electromagnetic (Qes: 0.54) Q factors confirm the driver’s balanced damping characteristics. Ideal for audiophile projects, the GRS 6SMP-8 delivers a refined listening experience with precise transient response and natural tonal balance.
