The Mackie SR18S powered subwoofer offers premium sound for working musicians, DJs, and venues alike. Its 1600-watt Class D amplifier packs reliable, consistent performance in a lightweight package, and its custom high-efficiency transducer ensures top-notch sound. A dedicated processing module guards against system overloads with the utmost in transparency. This state-of-the-art powered sub includes application-specific Custom Voicing presets for simplified setup; the SR18S also includes a variable crossover, easy system optimization features, versatile output options, and an integrated pole cup for your main speaker.

A flexible but easy-to-use subwoofer

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.

Transparent system protection guards against excessive levels

As the seasoned live sound experts here at Music Experience 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.

No More Excuses - A Loudspeaker Upgrade That Makes Sense

If you've been debating an upgrade to your sound system, the time has come to ditch those dusty old speakers from the 80's. With the SRT Series, experiencing incredible sound, cutting-edge performance, and reliability is a no-brainer.

Advanced Impulse™ DSP Module

What does it do for me? Mackie’s filtering technology is not your typical speaker processing. The goal of our Advanced Impulse™ DSP is to remove all the anomalies that loudspeakers and horns contribute to a signal, from “honkiness” or “squelch” to "mushy" low end, effectively making the drivers "invisible" and output nothing but perfect, clean sound. By more intelligently (and more thoroughly) employing the benefits of FIR filtering, Advanced Impulse DSP eliminates undesired acoustic anomalies across the entire dispersion zone (horizontal and vertical), as well as frequency range and time domain.Mackie Advanced Impulse DSP.

How It's Done

The main way this is accomplished is by measuring the negative frequency response and time domain impacts that each transducer and horn in the system introduces – on axis as well as off – and reversing/correcting for those anomalies before the signal hits the speaker. The result is the output from the speaker is fully corrected for flat, clear, time-aligned, and smooth sound throughout the entire time, space, and response domains.

Transparent System Protection

Other loudspeakers feature some sort of protection and limiting to help them squeeze a dB or two out of the speaker. This is almost always at the expense of sound quality and is commonly experienced as diminished bass response and the "pumping" sound of the internal limiter having a bad day. When operating at very high levels (ears beware), the processor-controlled system monitoring analyzes the audio signal and identifies the problem areas, then dynamically applies multi-band compression to those specific frequencies rather than lowering the overall output. This keeps your levels where you want them and maintains the sound quality you expect.
