The LS18 Sub-bass cabinet brings new versatility to NEXO GEO S12 line array systems and PS Series cabinets, delivering high SPL at a relatively low cost. Light and easy-to-handle, the LS18 uses a single 18″ long excursion driver and is compatible with all GEO S12 accessories, so it can fly with the S1230 and S1210 line array modules, or anchor a ground stack of S12 cabinets. With a steel stand fitting on top of the cabinet, the LS18 also allows for pole mounting of GEO S12 cabinets or NEXO PS15-R2 full-range speakers. LS18 can be flown in tandem with PS15s, which will be of particular interest to the installation sector.
