Mackie Thump118S 18-inch 1400W Powered Subwoofer

The Mackie Thump118S is a powered 18-inch subwoofer built to add deep, authoritative bass to live sound rigs. Its 1,400-watt Class-D amplifier drives a high-performance 18-inch woofer with a frequency response of 30 Hz to 200 Hz, producing the kind of visceral low-end that transforms a PA system from sounding adequate to sounding professional. The variable crossover gives you control over where the sub hands off to your top speakers, while custom voicing modes let you shape the bass response to suit different room sizes and musical styles.

On the connectivity side, the Thump118S features dual XLR inputs along with stereo full-range and highpass outputs. The highpass outputs are particularly useful — they send a filtered signal to your paired tops with the low frequencies already removed, simplifying system setup and reducing the need for an external crossover or processor. Adjustable level and polarity controls round out the rear panel, giving you the tools to integrate the sub cleanly into any speaker configuration. Designed to complement Mackie's Thump loudspeaker lineup, the Thump118S is equally capable of pairing with other brands, making it a versatile foundation for mobile DJs, bands, and event production crews who need reliable, powerful bass on demand.
