The Mackie Thump 15S V4 is a 15-inch powered subwoofer for PA systems. It pairs a 1400W Class-D amplifier with a 15-inch high-performance woofer. It reaches a maximum SPL of 132 dB and low-frequency performance down to 34 Hz.
The cabinet has built-in handles for easy loading. It is built to handle gigs while staying lightweight. An M20 thread accepts an SPM400 speaker pole, which is sold separately.
Four high pass modes let you match the subwoofer to your loudspeakers. Connect loudspeakers to the high-pass outputs and choose Thump 12, Thump 15, Thump GO or Variable. All modes include 1.4 ms alignment delay. Variable mode lets you set the crossover manually to match any loudspeakers.
