Mackie Thump18Sv4 is a high-performance 18-inch powered subwoofer built to deliver deep, powerful bass for DJs, live sound, and event production. With 1400W Class-D amplification and extended low-frequency response down to 25 Hz, it provides the low-end impact needed for full-range sound systems in demanding environments.
The Mackie Thump18Sv4 is designed for users who demand serious low-frequency performance. Its 18-inch high-output woofer and bass-reflex enclosure deliver deep, room-shaking bass that enhances music playback, live performances, and DJ sets with powerful punch and clarity.
With built-in high-pass modes, the Thump18Sv4 integrates seamlessly with a wide range of full-range speakers. Preset crossover settings are optimized for compatible speaker sizes, while a variable crossover range from 80 Hz to 160 Hz allows precise tuning for custom setups. This ensures balanced system performance and smooth frequency transitions.
The subwoofer features stereo XLR inputs along with both high-pass and full-range outputs, making it easy to connect mixers, controllers, and additional speakers or subwoofers. A mono summing option supports single or dual subwoofer configurations, and a phase invert switch allows alignment with main speakers for optimal low-end response.
Built for portability and durability, the enclosure includes ergonomic side handles for transport and an integrated M20 threaded pole mount for mounting full-range speakers above the subwoofer. Integrated protection circuitry ensures reliable operation, even during high-output use in demanding environments.
