Recessed handles makes the SX115 easy and safe to move from rehearsal space to stage and back again while heavy-duty rubber feet ensure that it stays put no matter how much volume you pump through it. Superior Sound Quality The SX115 delivers a big sound with a large, high-performance 15-inch LF driver (2.5-inch voice coil), and an exacting 1-inch HF driver. What's more, it utilizes a trapezoidal design which greatly decreases the resonance of the standing wave in the cabinet for a more true and exact sound reproduction. The SX115 is the perfect solution for club installations, rehearsal spaces, gigging musicians, mobile DJs, and houses of worships who need additional sound reinforcement.
