• RMS Power Handling: 1,500 Watts RMS. In real-world use, this sub is designed to sustain substantial bass energy when paired with a capable amplifier and properly tuned enclosure, providing clear impact without undue distortion.
• 3" High-Temperature Dual Voice Coil: A 3" voice coil built for higher temperature operation, improving power handling and thermal stability during long bass passages.
• Voice Coil Configurations: Available in B18 D2 and B18 D4 variants. D2 uses two 1.9 Ω coils per side (Re around 1.9 Ω), while D4 uses two 3.2 Ω coils per side (Re around 3.2 Ω). These configurations affect electrical load and damping characteristics.
• High-Excursion Design: Features 10" spiders to enable greater cone movement, delivering deeper bass with dynamic response when the enclosure and amp are properly matched.
• Double-Stacked Motor with FEA Cooling: A dual-motor design enhanced with finite element analysis cooling helps maintain performance under extended use by managing heat effectively.
• Cast Basket & All-Black Finish: Durable chassis combined with a sleek aesthetic that suits premium builds while resisting flex and providing lasting rigidity.
