The SW218UHP is an ultra-high-power, large-format subwoofer engineered for large venues and outdoor events demanding extended, high-impact low-frequency reproduction down to 30Hz.
Designed for versatility, the SW218UHP can be deployed individually or arrayed in multiples, either horizontally or vertically, utilizing VAL’s stacking system to ensure safe and secure stacking. Ground stacking is also compatible with VAL’s Point Source (QX, ZX series) and Line Array (VLA, WP, WCX series) systems.
At its core, the SW218UHP houses two custom-engineered 18”, 1500W RMS each, high-excursion drivers featuring 4.5” voice coils and die-cast aluminum frames. The direct radiating, bass-reflex cabinet design delivers a powerful, extended frequency response of 30Hz to 600Hz (-6dB), achieving a staggering peak SPL of 141dB.
The rugged enclosure is built for the rigors of touring and professional use, featuring a kick-resistant steel grille backed by reticulated foam, finished with a durable, textured, hard waterborne black coating. Two heavy-duty ergonomic handles per side ensure easy handling and transport.
Integrated rubber feet on multiple surfaces allow secure ground stacking in both horizontal and vertical orientations, locking into place via recessed stacking cups.
Dual integrated top-hat pole mounts (horizontal and vertical) provide maximum flexibility for pole-mounting full-range loudspeakers directly above the SW218UHP.
The rear panel features a precision-engineered cast aluminum connection plate fitted with dual 4-pin speakON® connectors (input and link), wired +1/-1 for the subwoofer signal and pass-through on +2/-2.
