The JFL118 is a light weight, high-powered, flyable, single 18-inch subwoofer that extends the low frequency response of the companion JFL210 or JFL213 full range line array loudspeakers. JFL118 subwoofers may be ground stacked, flown as part of a JFL210 or JFL213 array or flown separately alongside a JFL210 or FL213 array. Integral, proprietary rigging will suspend up to six of any combination of JFL118 and JFL210/JFL213 enclosures with a 10:1 design factor. The optional FB121 fly bar includes multiple suspension points that allow users to easily set an array’s tilt angle. The JFL118 also includes M10 threaded suspension points that allow users to deploy arrays in permanently installed applications by means of cost-effective, forged shoulder eyebolts. The JFL118 includes a metal cup that allows up to two JFL210 or JFL213 main channel loudspeakers to be pole mounted above up to two stacked JFL118’s. Alternately, JFL210 or JFL213 loudspeakers may be stacked directly atop the JFL118. In this instance, all enclosures lock together using their integral rigging.
