The HK Audio SL218 is a tour-grade passive subwoofer built for modern large-format PA systems. Dual 18-inch drivers in an 8-ohm configuration deliver fast, controlled low end down to 39 Hz, with 2000 W RMS power handling for confident headroom. With 105 dB sensitivity (1 W/1 m) and a maximum SPL of 139 dB, it provides authoritative, musical bass that scales cleanly for arenas, outdoor stages and high-demand club installs. A rugged 18 mm birch plywood enclosure, two-component black PU coating and heavy-duty steel grille ensure long-term durability on the road. Practical dimensions (120 x 56 x 79 cm) and an approximate 90 kg weight reflect its serious output and robust build. The SL218 integrates predictably with professional PA rigs, giving system techs reliable, repeatable results when time and consistency matter. Ideal for concerts, festivals, touring productions and large venues requiring powerful, accurate low-frequency reinforcement.
