Mackie Thump18S subwoofer

The Mackie Thump18S is a powerful 18-inch active subwoofer built to deliver deep, room-filling lows that anchor any live PA system. With a band-pass cabinet design and cool-running Class-D amplifier, it offers clean bass down into the low 30 Hz range with minimal distortion, even at high volumes. It includes dual XLR inputs (mono or stereo), versatile high-pass and full-range outputs for connecting tops or chaining more subs, plus level and polarity controls so you can integrate it smoothly into your speaker system. The rugged all-wood enclosure ensures durability for transport and gigs, making the Thump18S ideal for both indoor stages and outdoor events where solid bass presence is essential.
