The SW218HD is an ultra-high-output, large-format dual 18” slot-loaded subwoofer engineered for stadium-scale reinforcement, touring systems, and demanding outdoor applications requiring extended, high-impact low-frequency performance down to 30Hz. Designed to deliver exceptional acoustic power, the SW218HD combines extreme output capability with precise and controlled low-frequency reproduction for large venues, concert sound, festivals, and high-energy live productions.
Optimized for flexible deployment, the SW218HD can be used individually or configured in horizontal or vertical arrays using VAL’s integrated stacking system, ensuring secure and stable deployment in both touring and fixed-install environments. The enclosure is fully compatible with VAL Point Source systems (QX, ZX Series) and Line Array systems (VLA, WP, and WCX Series) for seamless large-scale system integration.
At the heart of the SW218HD are two custom-designed 18” high-excursion transducers, each rated at 1500W RMS, featuring oversized 4.5” voice coils and robust die-cast aluminum frames for superior thermal efficiency, high linear excursion, and long-term reliability under extreme operating conditions. The advanced slot-loaded, direct-radiating bass-reflex design enhances low-frequency coupling and efficiency while delivering a powerful frequency response of 30Hz – 600Hz (-6dB) with an impressive peak SPL of 142dB.
Built to withstand the demands of professional touring, the enclosure features a heavily reinforced cabinet construction finished in a rugged textured waterborne black coating. A kick-resistant steel grille with acoustically transparent reticulated foam provides maximum driver protection while maintaining airflow and acoustic transparency. Multiple heavy-duty ergonomic handles ensure efficient transport and handling. Integrated rubber feet and recessed interlocking stacking cups enable secure ground stacking in both horizontal and vertical orientations.
For maximum system versatility, dual integrated top-hat pole mounts are provided for both horizontal and vertical deployment configurations, allowing direct mounting of full-range loudspeakers above the subwoofer enclosure.
The rear connection panel utilizes a precision-engineered cast aluminum interface fitted with dual 4-pin speakON® connectors (Input / Link), wired +1/-1 for subwoofer operation with pass-through connectivity on +2/-2 for simplified system cabling.
