Product Description

  • Woven Fiberglass Composite Cone
    All Reference R3 woofers use fiberglass stranding woven together for ultimate strength and less elasticity. A heavy soaking in epoxy combined with the sonic qualities of pulp paper backing proves itself worthy of any system.
  • 100% OFC 4-Layer Voice Coil
    R3 woofers use generous 1.50″ long, 2.5″ diameter 100% OFC Copper voice coils. A vented Aluminum former extract and dissapate any heat build-up, resulting in improved power handling.
  • Extended Excursion Polyurethane Surround
    Polyurethane is a foam compound used in the manufacture of countless gasket and insulation products, known for its adhesive bonding properties. Reference R3 woofers utalize an extended excursion polyurethane surround for it’s strength and flexible properities during extreme movement.
  • Back Plate & T-Yoke Venting
    Heat build-up is a leading cause of catastrophic woofer failure. Venting built into the T-Yoke, back plate, and voice coil extract and dissapate heat, ensuring R3 woofers keep their cool.
