Description

The Mackie Thump18Sv4 is a high-impact powered subwoofer designed to bring deep, powerful bass to live sound setups, DJ systems, and event spaces. Built to complement full-range loudspeakers, it adds the low-frequency depth needed to give music a fuller, more immersive feel. Despite its commanding output, it remains practical for transport and setup, making it a reliable addition to both portable rigs and more permanent installations.

Equipped with a 1400W Class-D amplifier and an 18-inch high-performance woofer, the Thump18Sv4 delivers strong, room-shaking bass with impressive clarity and control. It reaches down to 25 Hz, providing the kind of low-end extension that enhances everything from punchy kick drums to deep electronic basslines . Designed to integrate seamlessly with Thump series loudspeakers, it offers selectable high-pass modes and a variable crossover option, allowing you to tailor the system to your specific speakers and environment.

Connectivity is straightforward and flexible, with stereo XLR inputs and both high-pass and full-range outputs for easy system expansion. Features like phase inversion, level control, and mono or stereo operation help fine-tune performance, while the rugged enclosure, built-in handles, and M20 pole mount make setup simple and dependable. Whether used for live music, events, or installations, the Thump18Sv4 provides the low-end foundation that brings a sound system to life.
