The Mackie Thump18Sv4 is an 18-inch powered subwoofer with a 1400W Class-D amplifier, rated for 132 dB max SPL and response down to 25 Hz. It pairs with Thump v4 loudspeakers through selectable crossover modes, and a variable mode lets you set the crossover yourself. It is built for gigging DJs, bands and small venues that need floor-shaking low end without hauling a large rig. Against lighter 12- and 15-inch subs it trades portability for deeper bass and more output, and its molded cabinet with carry handles is easier to move than most 18-inch boxes.

Owners describe the Thump18Sv4 as a loud, deep sub for the money, with crossover modes that make pairing with Thump tops simple. Most praise its output and punchy kick for DJ and band use; the main complaints are weight and the pole being sold separately.
The Mackie Thump18S v4 is a professional powered subwoofer for PA systems. It pairs a 1400W Class-D amplifier with an 18" high-performance woofer. The woofer reaches a maximum SPL of 132 dB and low-frequency performance down to 25 Hz.
Selectable crossover modes tailor the sound to the size of the connected speakers, and a variable mode lets you set the crossover yourself. It integrates with Thump loudspeakers and can be used with other PA speakers.
You can stack a Thump v4 speaker on top of the subwoofer or stack multiple subs on top of each other. You can also mount a speaker above the sub with the Mackie SPM400 speaker pole, sold separately. Built-in carry handles make it portable for touring or gigging setups. A custom Mackie slip cover is also available separately.
