The DFT-21B features a high-performance, high-power, lightweight, versatile, and exceptionally compact cabinet design, equipped with a premium-quality 21-inch (100mm voice coil) subwoofer. The cabinet boasts a sleek, space-saving design and a flawlessly engineered multi-purpose rigging system, making installation effortless and enhancing portability for on-the-go use. It delivers an immersive listening experience with remarkable clarity and a well-balanced soundstage.
The DFT-21B low-frequency speaker features a high-efficiency 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 resonance, while simultaneously 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 impressive low-frequency extension and output capability.
