A heavy soaking in epoxy combined with the sonic qualities of pulp paper backing creates a premium feel. Features Woven Fiberglass Composite Cone Phantom subwoofers use fibreglass stranding woven together for ultimate strength and less elasticity. A heavy soaking in epoxy combined with pulp paper backing’s sonic qualities proves itself worthy of any system. 100% OFC 4-Layer Voice Coil 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 to manufacture countless gasket and insulation products, known for its adhesive bonding properties. Phantom subwoofers utilize an extended excursion polyurethane surround for strength and flexibility 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 Phantom subwoofers keep their cool.
