Mackie SR18S 18" 1600 Watt Professional Powered Subwoofer
When your gig demands earth-shaking low end that doesn't quit, the Mackie SR18S steps up to deliver. This 18-inch powerhouse isn't just another subwoofer — it's the foundation that transforms your PA system from good to absolutely thunderous, whether you're rocking a packed club or powering through a festival stage.
Built to Rumble, Designed to Last
Built for the grind of real-world performances, the SR18S combines 1600 watts of Class-D power with smart acoustic processing that keeps your sound tight and controlled. Three Custom Voicing presets let you dial in exactly the flavor of bass your music demands, while the Built-Like-A-Tank construction ensures this beast will handle whatever you throw at it, gig after gig.
1600W Class-D Amplifier: Delivers consistent, reliable power that won't leave you hanging mid-set. Class-D technology means maximum output with minimal heat, so your subwoofer stays cool under pressure.
Custom High-Efficiency Transducer: This isn't your average driver — it's engineered specifically for maximum punch and clarity, ensuring every bass note cuts through the mix with authority.
3 Custom Voicing Modes: Flat gives you natural balance, Deep digs into those sub-basement frequencies for electronic and hip-hop, and Punch cranks the output for rock and live bands that need to move air.
Performance That Handles the Heat
The SR18S isn't just about raw power — it's about smart power. The dedicated processing module keeps everything running smoothly, even when you're pushing levels that would make other subs wave the white flag.
Transparent System Limiting: Your sound stays clean and balanced even under heavy limiting, so you can push hard without sacrificing quality. No more choosing between volume and clarity.
Input Limiting Protection: If your source signal runs a little hot, the SR18S automatically keeps things in check, protecting both your ears and your equipment from unwanted distortion.
Variable Crossover Control: Fine-tune exactly where your subwoofer hands off to your full-range speakers, ensuring seamless integration with any PA system.
Built-Like-A-Tank Construction Meets Real-World Versatility
Despite its rugged construction, the SR18S knows that mobility matters when you're hauling gear from venue to venue. The robust wood cabinet and steel grille can take the abuse, while thoughtful design keeps load-in and setup manageable.
Versatile I/O Options: Stereo XLR inputs and outputs plus dedicated high-pass outputs give you the flexibility to configure your system exactly how you need it, whether you're running single or dual subs.
Universal Power Supply: The 100-240VAC power supply with Power Factor Correction keeps your subwoofer running stable, even when venue power is less than perfect.
Integrated Pole Cup: Mount your full-range speakers directly on top for a clean, professional setup that maximizes your stage real estate.
The Foundation Your System Has Been Waiting For
The Mackie SR18S doesn't just add bass to your PA — it transforms your entire system's efficiency and output. By handling the demanding low-end work, it frees up your full-range speakers to focus on what they do best, resulting in cleaner mids and highs across your entire mix. Whether you're complementing SRT or SRM Series speakers or integrating with any professional PA, the SR18S delivers the rock-solid foundation that turns good sound into unforgettable sound.
