The HFT-21B features a high-performance, high-power, lightweight, versatile design with an exceptionally compact cabinet—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 mobile use. It delivers a powerful sense of presence, outstanding clarity, and remarkable balance.
The HFT-21B low-frequency speaker features a high-efficiency neodymium magnet driver unit and an optimally tuned, curved 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.
The HFT-21B's numerous innovative technologies virtually eliminate audible distortions such as popping sounds within the audible range, enabling a remarkably smooth extended response without the extraneous noises typically associated with conventional equipment. Mathematically optimized, these features can meet the most ideal requirements within the array.
Like all Real enclosures, the HFT-21B cabinet is crafted from Baltic birch plywood, featuring a robust black epoxy finish designed to withstand even the harshest conditions. The speaker grille is made from premium 14-gauge perforated steel and coated with a highly durable, water-resistant commercial-grade powder coating.
