Mackie Thump18Sv4 – 18’’ 1400 W Subwoofer for DJ & Live Systems

The Mackie Thump18Sv4 is the most powerful subwoofer in the Thump V4 series. Featuring a massive 18-inch driver and an ultra-efficient 1400 W Class-D amplifier, it delivers deep, powerful and highly accurate low frequencies. With a response extending down to 25 Hz and significantly greater impact than the 15’’ model, it provides a spectacular low-end foundation for DJ systems, live sound setups and professional installations.

Optimized to work in perfect synergy with the Thump V4 range, the Thump18Sv4 features several high-pass filter modes tailored to different speakers: Thump12v4, Thump15v4, Thump GO, as well as a Variable mode allowing precise adjustment of the crossover point depending on the setup.

The full connectivity includes stereo XLR inputs, high-pass XLR outputs for satellite speakers, and full-range XLR outputs (with mono switch) for chaining multiple subwoofers. The Thump18Sv4 also provides essential tools such as phase inversion, fully muteable level control, a defeatable LED, mono/stereo selection, and intuitive operation for fast deployment.

Built with the extremely rugged “Built-Like-A-Tank™” design, this subwoofer is engineered to withstand touring, frequent use and demanding environments. Despite its power, it remains easy to handle thanks to ergonomic handles and an M20 pole mount thread.

Whether for DJs, live bands, event providers or venues, the Mackie Thump18Sv4 delivers massive, clean and extremely deep bass reinforcement. It is the ideal solution for systems requiring more low-end headroom compared to the 15’’ model.
