Some times a woofer comes along that changes the game. The R3 is just that. It has a high roll surround for extended excursion. With a big 2” voice coil, and a gigantic motor structure, it can handle some serious power. With unparalleled sound quality, this little woofer can get down and hang with just about any other 8” woofer out there. Weather an SPL competitor or an SQ competitor this is a woofer that can do it all.
- 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.
