The Mackie Thump 115S is a 15" powered subwoofer engineered to add deep, controlled low end to any Thump PA system. A 1400W Class-D amplifier drives the high-output woofer to a peak SPL of 131 dB, while four voicing modes and a variable crossover let operators tune the bass to the room and the music. Stereo XLR I/O with high-pass and full-range outputs makes it easy to integrate with tops, monitors, or a second sub.
