NEW GRS 6-1/2" Woofer Surface Mount Poly Cone 8 Ohm 6SMP-8

GRSPart # 292-864
Model: 6SMP-8

The GRS 6SMP-8 is a 6-1/2" 8 ohm woofer engineered for easy surface mounting and reliable performance. Its damped poly cone, paired with a durable rubber surround, ensures a natural and controlled sound. The motor incorporates a copper cap, significantly reducing inductance and distortion for clarity. Enhanced cooling is achieved through a vented pole piece and an aluminum voice coil former, keeping power compression to a minimum. Additionally, the lightweight 2-layer voice coil and powerful motor enhance efficiency. The GRS 6SMP-8 is a great choice for smaller 2 and 3-way designs, or for revitalizing older speaker systems.

Key Features

  • Copper cap in the motor lowers inductance and distortion for more accurate response
  • Damped poly cone with rubber surround controls resonance for a smooth natural response
  • Vented pole piece and aluminum voice coil former improve cooling to limit compression
  • Low profile frame supports surface mounting for easy installation
  • Flexible enough for use in sealed or vented enclosures, great choice for 3-way designs

Overview

GRS 6-1/2" Woofer Surface Mount Poly Cone 8 Ohm 6SMP-8

The GRS 6SMP-8 is a 6-1/2" 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 6SMP-8 delivers good efficiency for high output without requiring a ton of power.

The 6SMP-8 is an excellent choice for both sealed and vented enclosures, making it a versatile addition to 3-way speaker designs. Furthermore, its compatibility with many classic speaker systems opens the door to exciting possibilities for rejuvenating your existing audio setup. This driver not only breathes new life into your sound system but also provides a practical solution for enhancing your overall listening experience.
