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 extracts and
dissapates any heat build-up, resulting in improved power
handling.
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.
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 it’s strength and flexible
properities during extreme movement.
Woven Fiberglass Composite Cone
All Reference R3 woofers use berglass 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.
