Mackie Thump118S 1,400W 18-Inch Powered Subwoofer

If your PA needs low end you can feel in your chest, the Thump118S delivers it. The 18-inch driver and 1,400 watts of Class D power produce deep, powerful bass that transforms any system from sounding thin to sounding massive. Whether you're pairing it with Thump tops, Thrash speakers, or any other powered PA, this sub fills in the bottom end that smaller speakers simply cannot reproduce.

Dual XLR inputs with selectable full-range and high-pass outputs make integration with your existing tops straightforward -- the high-pass mode sends everything above the crossover point to your tops while the sub handles the lows. A polarity switch helps you dial in phase alignment between the sub and your mains. For bands, DJs, and event productions that need real bass impact, this sub does the heavy lifting.
