Designed for DJs, PA systems, and pro-audio enclosures Powerful 3-Inch Voice Coils: Each driver features a 3" high-temperature CCAW voice coil rated for high SPL output and sustained operation under extreme heat. The ultra-saturated magnetic gap and 90 Oz magnet produce strong motor force and excellent control for deep, tight bass response during live or recorded playback. Durable Fiber-Reinforced Cone: Built with a fiber-reinforced, ultra-stiff paper composite cone and paper dust cap for strength and accuracy. Accordion-edge cloth surround and linear progressive Conex spiders maintain linear excursion while minimizing distortion. Expanded rolled steel basket enhances rigidity and long-term reliability. Precision-Tuned Performance: With a frequency response of 26 Hz-500 Hz, these subs deliver clean, extended low-end for DJ cabinets, stage monitors, or sub enclosures. Sensitivity of 101 dB @ 1W/1m ensures efficient power conversion, while 8-Ohm impedance and dual nickel-plated banana plug terminals provide secure, corrosion-resistant connections. Pro-Grade Construction: Mounting depth of 7.17 in fits most standard 18-in enclosures. High BL magnetic motor gap ensures maximum cone control at high excursion.
