The Alto TS 15S is an active 15-inch subwoofer with 2500 watts of peak power, providing the essential bass foundation for any PA system. Three DSP-controlled crossover modes automatically adapt the sub to various top speakers, while the stack-out sends the signal directly to your full-range cabinets. Ideal for concerts, DJ sets, weddings, and corporate events for up to 300 people where punchy, precise bass is required.
