The UX-221 is a high-power ultra low frequency subwoofer system designed to provide outstanding performance in terms of output power, bandwidth extension and distortion.
The UX-221 comprises two 21" loudspeakers equipped with 6" voice coils and offers a power handling capacity of 8000 Wpeak each loudspeaker. The impressive 60 mm peak-to-peak excursion, powerful neodymium magnet assembly and double silicone spider with optimized compliance provide for commanding low frequency response.
The enclosure is constructed using 21 mm Birch plywood and makes use of extensive bracing to eliminate
resonances. The woodwork is finished with the robust D.A.S. ISO-flex protective coating for durability.
A dolly platform with locking casters denominated the PL-221S is offered to stack and move the systems. Protection during transport is provided by the optional covers available from D.A.S.
