Mackie Thump 15S V4 15" Active PA Subwoofer

The Mackie Thump15S V4 is a powerful 15-inch active subwoofer designed to add deep, impactful low-end performance to PA systems, DJ rigs and live sound setups. Featuring a high-efficiency 1400W Class-D amplifier and a high-output 15-inch woofer, the Thump15S V4 delivers impressive bass response down to 27 Hz and a maximum SPL of 132 dB, providing the foundation needed for music-focused events, live performances and professional audio applications.

Engineered to integrate seamlessly with a wide range of loudspeaker systems, the Thump15S V4 features selectable high-pass modes that optimise crossover settings for different speakers, including dedicated presets for Mackie Thump series loudspeakers. For users requiring greater control, a variable crossover mode allows precise frequency adjustment, helping to achieve the perfect balance between subwoofer and top speakers. Built-in alignment delay ensures smooth and coherent system performance across all modes.

Connectivity is simple and flexible thanks to stereo XLR inputs and outputs. High-pass outputs allow direct connection to full-range loudspeakers with the appropriate crossover applied, while full-range outputs provide an unprocessed signal for connecting additional subwoofers or expanding larger sound systems. A mono summing option further increases system flexibility for a variety of setup configurations.

Built for life on the road, the rugged enclosure is designed to withstand regular transport and demanding event environments. Integrated carry handles make loading and positioning easier, while the M20 threaded pole mount enables secure mounting of full-range speakers directly above the subwoofer for a clean and professional PA setup.

Additional practical features include variable level control for precise system balancing, a phase invert switch for optimising bass response, and a defeatable front-panel LED for situations where discreet operation is preferred.
