DFT-18Bi features a high-performance, high-power, lightweight, versatile, and highly compact cabinet design, equipped with a premium-quality 18-inch (100mm voice coil) subwoofer. The compact cabinet design ensures easy installation, making fixed mounting particularly convenient, while delivering a powerful sense of presence, exceptional clarity, and balanced sound reproduction.
The DFT-18Bi low-frequency speaker features a highly efficient neodymium magnet driver unit and an optimally tuned, arc-shaped bass reflex port design. Internally, it incorporates a scientifically engineered approach to eliminate standing waves and resonances, while also minimizing weight without compromising essential rigidity. The bass reflex port openings have been specially optimized to reduce port noise and further enhance low-frequency performance. The result is an impressively extended low-frequency response and outstanding output capability.
