Thump 18Sv4 Subwoofer

The subwoofer also includes an M20 thread for optional poles, built-in carrying handles and a switchable front LED.

Perfect Complement for Thump v4 Speakers

The Thump 18Sv4 was developed specifically as the ideal complement to the speakers in the Mackie Thump v4 series. Especially when paired with the Thump15v4 it creates a powerful full-range system with impressive bass response and excellent speech intelligibility. The integrated crossover presets let you optimally match the sub to various top units, ensuring balanced signal distribution and a cohesive sound across the entire frequency range.

Massive Bass for DJs, Live Shows and Events

With its powerful 18" woofer, the Thump 18Sv4 significantly extends the low end and reproduces deep frequencies down to 25 Hz. That makes the subwoofer ideal for electronic music, club sound, live bands, mobile DJs, weddings, corporate events, presentations and parties. Its high output and maximum SPL of 132 dB ensure controlled, punchy bass even at high volume levels.

Flexible DSP Control and Professional Connections

The integrated DSP section enables quick adaptation to different speaker systems and venues. In addition to fixed crossover settings for Thump tops, a variable crossover frequency is available. Phase inversion and mono/stereo modes let you tailor the setup to the room and application. Thanks to professional XLR connectors, the subwoofer integrates easily into existing PA systems.

Rugged Design for Mobile Use

The sturdy enclosure and integrated handles make the Thump 18Sv4 ideal for life on the road. Despite its high output, the subwoofer remains transport-friendly and easy to handle. The built-in M20 thread allows mounting an optional pole to secure top cabinets directly above the subwoofer. That makes the Thump 18Sv4 equally suited for stage, rental, clubs, rehearsal rooms and mobile event setups.

Pole

With Pronomic poles you can mount tops directly on subwoofers — at the correct height. Almost all subwoofers already feature the appropriate receptacle. The poles screw into the M20 thread and a locking pin with a securing screw prevents accidental slipping. The robust construction guarantees long life even under the toughest road conditions.
