Alto Tourmax SX115 15 inch 2 Way Passive PA Speaker Overview:Quality Sound Meets Rugged DesignRoad ReadyBuilt to take a beating night after night, week after week, the SX115 features a heavy-duty steel grill that’s built to last, and its cabinet is covered in a ruggedized black textured finish that is scratch and dent resistant. 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 QualityThe 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.Features:
