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 dissipate 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 utilize an extended excursion polyurethane surround for its strength and flexible properties 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, backplate, and voice coil extract and dissipate heat, ensuring R3 woofers keep their cool.
