The SP 218 is a dual 18-inch passive subwoofer engineered for high-output live sound reinforcement where a single driver simply is not enough. Twin 18" Pro Rider woofers work together within a single enclosure, delivering 2,400 watts of program power handling and 4,800 watts peak enough low-end displacement to fill festival stages, large venues, and outdoor events with authority. Low frequency response extending down to 41Hz ensures that kick drums, bass fundamentals, and sub-bass content are reproduced with weight and definition rather than just volume.
Connectivity on the SP 218 is built for professional deployment. A four-pin twist lock connector and two 1/4" phone jacks run in parallel for standard system integration, while the Neutrik Speakon switching jack provides independent access to each woofer for bi-amplified configurations. The built-in threaded pole mount plate keeps full-range tops securely positioned overhead, and tilt-back casters make repositioning a cabinet of this size practical without additional equipment.
