The UX-218 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-218 comprises two 18UXN loudspeakers
equipped with 4" voice coils and offers a power handling
capacity of 4400 Wpeak each loudspeaker. The
impressive 52 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 18 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-UX218S is offered to stack and move the systems.
Protection during transport is provided by the optional
covers available from D.A.S.
