Mackie Thump15Sv4 15-inch 1400W Powered Subwoofer

The Thump15Sv4 is the 15-inch subwoofer in Mackie's V4 line, delivering 1400W of Class-D power and 132 dB max SPL with low-frequency output to 34 Hz. It is a lighter, more portable sub for mobile rigs that still want real low-end reinforcement.

Four selectable high-pass crossover modes - tuned for Thump 12, Thump 15, Thump GO, or Variable - plus a 1.4 ms alignment delay, phase-invert switch, and stereo/mono summing make it easy to integrate cleanly with matching tops. At 57.4 lb with pole-through mounting, it stacks into a tidy full-range system.
