ASS-W121-F, a single 21-inch active subwoofer with a digital amplifier module, features a direct-fire inverted-phase cabinet design and a built-in 1x21" 115mm voice coil woofer that ensures a strong low-frequency impact and depth. The cabinet construction uses multi-layer composite plywood with an outer layer of abrasion-resistant polyurea paint to enhance durability and protection. The subwoofer is compatible with line array and point source full-range speakers, which can significantly improve the system's low-frequency response and is suitable for a variety of professional audio application scenarios.
