Feel every beat. The Mackie SR18S 18" Active Subwoofer adds depth and detail to your live sound system. With 1600W peak power on board, you can explosive volumes without ever compromising on clarity. That means smooth, articulate bass that everyone can enjoy.
Built for maximum performance. The SR18S boasts deep, responsive low-end all the way down to 33Hz. Thanks to a custom high-efficiency 18" woofer, you've got maximum punch for every type of performance. Add to that three voicing presets, and you've got perfectly tuned audio fit for any occasion.
Take centre stage with confidence. The SR18S takes the hassle out of live sound so you can concentrate on what you do best. With stereo/mono summing, variable crossover frequency, and polarity invert controls on board, flawless optimisation is a guarantee. All you have to do is plug in and play.
Fine tune every detail
From concert halls to bars and clubs. Every venue is different. So you need a system that adapts. That’s why the SR18S lets you fine-tune your sound at the touch of a button. Three built-in voicing presets allow you to fine-tune the sound of your speaker. Choose ‘Flat’ for natural balance, ‘Deep’ for emphasised low-frequencies, or ‘Punch’ for the highest possible output level. However you perform, wherever you are, you’ve got the best sound possible.
Completely protected
When you’re performing with passion, it’s easy to overdo it. But with the SR18S, you’ll never have to worry about high-output signals damaging your speaker. A dedicated processing module monitors and protects the amplifier in real-time. That means that even if you’re sending audio that’s too hot, the speaker will correct it automatically. The result is balanced tone without the worry.
