GRS 10" Woofer Surface Mount Poly Cone 8 Ohm 10SMP-8

The GRS 10SMP-8 is a 10" woofer with a low profile frame designed for easy surface mounting, making it a great choice for new installations or retrofits in older speaker systems. Its design focuses on accurate response and long-term reliability, ensuring that you can enjoy consistent performance for years to come.

Crafted with a damped poly cone and rubber surround, this woofer provides a natural and well-controlled response. The inclusion of a copper cap in the motor helps to reduce inductance and distortion, allowing for clearer and more accurate reproduction. Additionally, an integrated foam gasket ensures an airtight seal within the cabinet. The vented pole piece and aluminum former work together to keep the voice coil cool, minimizing power compression and maintaining sound integrity even at higher volumes. Thanks to a lightweight 2-layer coil the 10SMP-8 delivers good efficiency for high output without requiring a ton of power.

Optimized for use in sealed enclosures, the 10SMP-8 is particularly well-suited for larger 3-way speaker designs. In addition, this driver is compatible with many classic speaker systems making it a great option for breathing new life into your existing sound system.
