Features: - Paper Cone - Motor Performance - Temperature Resistant - Stamped Basket The paper cone of the 18-inch woofer is both rigid and lightweight, which eliminates flex under the high-power application. This design improves bass response and allows the DJ subs to handle more power. The motor structure of the replacement speaker is designed for maximum magnetic force to improve power efficiency. Our subwoofers' high-temperature voice coil can perform under higher-than-normal degrees, with less fatigue and increased performance and efficiency during heavy-duty and prolonged playtime. Our 18-inch subwoofer also features a stamped basket that can absorb and transfer much of the energy produced by the subwoofer. This design ensures the subwoofers remain in excellent condition and deliver optimal sound quality.
