When your sound system needs that earth-shaking foundation, the Mackie Thump 118S delivers bass that doesn't just fill the room — it commands it. This powerhouse subwoofer transforms any venue into an immersive sonic landscape where every kick drum hits like thunder and every bass line resonates with crystalline clarity.
Why the Thump 118S Stands Out
The Thump 118S isn't just about volume; it's about precision. With 1400 watts of Class-D power driving an 18" high-performance woofer, you get massive output without sacrificing clarity. The intelligent voicing modes let you sculpt your sound for any genre — from the deep rumble that electronic music demands to the punchy attack that makes rock really kick.
Three Custom Voicing Modes: Flat mode delivers natural balance for versatility across genres, Deep mode emphasizes ultra-low frequencies perfect for dance and electronic music, while Punch mode maximizes output for bands and rock performances.
Variable Crossover Control: Fine-tune where your subwoofer hands off to your main speakers, ensuring seamless integration that sounds like one cohesive system rather than separate components.
Flexible I/O Configuration: Stereo XLR inputs, full-range outputs, and high-pass outputs give you the connectivity options to integrate seamlessly with any existing setup.
Effortless Integration and Control
The Thump 118S understands that great bass is only as good as your ability to control it. Every knob, switch, and connection point serves a purpose in helping you achieve the perfect low-end foundation for your mix.
Polarity Invert Switch: Eliminates phase cancellation issues when multiple subwoofers are deployed, ensuring your bass frequencies add together rather than fight each other.
Variable Level Control: Dial in the exact amount of bass reinforcement your system needs with precision control from -6 dBU to +6 dBU.
Mono/Stereo Summing: Whether you're running a single subwoofer or multiple units, the flexible input configuration adapts to your setup requirements.
Built for the Road, Designed to Last
Professional audio equipment lives a demanding life, and the Thump 118S embraces that reality with thoughtful engineering that prioritizes both durability and practicality.
Built-Like-A-Tank Construction: Engineered to withstand the rigors of professional use while remaining surprisingly portable for an 18" subwoofer.
Ergonomic Corner Handles: Redesigned grip points make loading and positioning easier than ever, reducing strain during setup and teardown.
Integrated M20-Threaded Pole Mount: Mount your main speakers directly on the subwoofer for clean, professional-looking installations.
The Foundation Your System Deserves
The Thump 118S represents more than just another subwoofer — it's the missing piece that transforms good sound into unforgettable audio experiences. Whether you're reinforcing a band's low end or providing the foundation for a DJ set that keeps people moving, this subwoofer delivers the kind of bass response that audiences feel as much as they hear.
