Mackie Brings the Low-end Thump!

The Mackie Thump 118S powered subwoofer brings the bass to your system, sporting a robust 18-inch high-performance woofer and 1,400 watts of class-D power! This versatile subwoofer features both highpass and full-range outputs to allow for flexibility in your loudspeaker setup, while the three different crossover presets — Flat, Deep, and Punch — allow you to tailor the Thump118S’ response to your specific musical application. Plus, the Thump118S boasts the heavy-duty construction that Mackie is renowned for, with an ergonomic design that makes this sub ideal for touring and gigging applications. Whether you’re looking to outfit your system with some ground-shaking low end or you simply need a rock-solid subwoofer, Sweetwater highly recommends the Mackie Thump118S!

Three versatile crossover presets

Earth-shaking hip-hop sub-bass? Check. High-octane rock? Check. Everything else? Check! The Mackie Thump118S comes with three crossover presets that are tailored to a variety of musical applications. For hip-hop and electronic dance music, Deep will be your preferred setting, with a rich emphasis on the lowest low frequencies. Punch offers an excellent balance between your deep low-end frequencies and overall output, and it’s the setting of choice for rockers and other more aggressive applications. For everything else, Flat delivers a balanced response that’s perfect as a one-size-fits-all preset.

Road-ready durability

Mackie’s motto is that their products are “built like a tank,” so it’s really no surprise that the Thump118S boasts a heavy-duty construction that can easily handle even the most challenging of live sound environments. If you’re a gigging musician or on tour, you’ll be sure to appreciate the Thump118S’ road-ready construction and lightweight form factor, coming in at a manageable 65.5 pounds. What’s more, this sub’s top corner handles make it a breeze to lift, and when you’re setting up your rig onstage, the integrated M20-threaded pole mount offers wide-ranging compatibility.

Rated 5/5

Great Sound

This sub has really good sound. No distortion detected during use. As of now, we are just running one but will soon purchase another. It is paired with 2 LD ICOA 15s set on satellite preset. The adjustable crossover on the sub helps with the mains and separates the sound correctly.

Mackie thump118s

The best powered subwoofer and perfect bass….
Rated 4/5

Good overall subwoofer

As a small time band member who is responsible for the gear at the events we do, I need to research and provide the system that packs a punch. I started with my tops, the alto ts315, and they do hold up well in the rough small venues we do. I added this sub to my rig, and wanted to know how it sounded. Holy cow. It is extremely clean punchy bass, compared to the Behringer 1800s that I wanted to look at. The only thing I needed to do to get it sounding perfect with my setup was to add an external preamp, to get the sound loud enough to hear with my 2 tops. I know it is only one sub, but 132db should be louder, even with the sonic differences of bass. That is all that I needed to do to get it up to the loudness that was lacking, say if you just plugged it from the mixer to the sub. I didn't want to really push the volume up too much, since that is not what the sub is meant for, but either I get another sub or a second one of this brand to fill the much needed low end. it is a great surprisingly easy to carry sub, but the volume is not there if you don't plan on adding something in the signal flow to amp it up more. Another thing is that the settings on the presets are not saved when you turn the sub off, they revert back to the original preset, the flat response. overall, good sub!
