<h3>A flexible but easy-to-use subwoofer</h3>
If you play different rooms of different sizes, you'll love the flexibility of the SR18S. And no matter what your system looks like on any given night, the SR18S is easy to set up. The perfect complement to your SRT Series, SRM | V-Class Series, or any other PA loudspeakers, SR18S not only reinforces your low end, but also allows for a massive increase in system efficiency and output. Custom Voicing presets and a variable crossover makes it easy to fit the SR18S into the mix. You also get a polarity invert switch, stereo and mono summing for single- or dual-subwoofer deployment, and a variable level control that ranges from -6dBU to +6dBU. What's more, because it has dual full-range outputs in addition to dual highpassed outputs, you can integrate the SR18S into virtually any PA system.
<h3>Transparent system protection guards against excessive levels</h3>
As the seasoned live sound experts  will tell you, unpredictable level spikes are a fact of life. The Mackie SR18S takes this into account, providing you with a dedicated processing module that monitors your amplifier in real time to guard against excessive levels. It's extremely transparent — even under heavy limiting. What's more, input limiting tames extra-hot sources before they cause issues. You also get Power Factor Correction for rock-solid operation in venues with unstable power.
