        Highlights of the GRS 12SMP-8

        • Durable damped poly cone with rubber surround ensures controlled resonance and smooth bass
        • Copper cap on the pole piece minimizes inductance and reduces distortion for cleaner sound
        • Shallow-profile steel frame for easy integration into surface-mount applications
        • Vented pole piece and aluminum voice coil former enhance cooling and thermal performance

         

        Product details GRS 12SMP-8

        GRS 12SMP-8 12" Surface Mount Woofer 8 Ohm

         

        The GRS 12SMP-8 is a versatile 12-inch woofer specifically tailored for surface-mount installations where space efficiency and low-frequency output are crucial. Its damped poly cone and rubber surround work in tandem to reduce unwanted resonances, delivering controlled and deep bass extension down to 20 Hz. A vented pole piece and aluminum voice coil former promote efficient heat dissipation, minimizing power compression during extended operation. With a sensitivity of 89.5 dB and a 90-watt RMS power handling, this driver offers a balance of power and performance. The integrated foam gasket ensures a tight cabinet seal, while the low-profile frame allows for seamless mounting in tight enclosures. Ideal for both new speaker projects and refurbishments, the GRS 12SMP-8 is a solid choice for audiophiles and DIYers alike.
