PRODUCT OVERVIEW

Featuring a built-in crossover at 140 Hz, stereo high-pass outputs, and full-range outputs, the Thump18S allows you to connect top speakers and additional subwoofers without any extra hardware.

Using efficient Class-D amplification and a dynamic bass frequency response, the speaker is designed to deliver a clear and present low end at any volume. The Mackie Thump118S is a powered subwoofer that features an 18" custom high-output woofer. With 1400 watts of power, you get the high bass output you need in a package that is designed to be tough and portable.

What truly sets the Thump118S apart are its selectable voicing modes—Flat, Deep, Punch, and Variable—allowing you to tailor the bass character to the genre or the venue’s needs. Whether you're seeking balanced low-end, earth-shaking sub-bass, rock-driven punch, or fine-tuned crossover settings, this subwoofer adapts with precision. Additionally, versatile I/O options—including stereo XLR inputs, as well as full-range and high-pass outputs—combined with controls for polarity inversion, stereo/mono summing, and level adjustment, make system integration intuitive and flexible.
