The JBL IRX-115S is a 15-inch powered subwoofer for portable PA systems, rated 1,300 W peak (600 W RMS) with a bass-reflex ported cabinet. It extends IRX full-range speakers down low, with built-in crossover and polarity controls so it pairs without extra processing. At about 65 lb it is light for a 15-inch sub, which suits mobile DJs and small bands. Against pricier 18-inch subs it gives up some output and depth, but it is simpler and easier to move than most.
