The Thump Your Setup Craves

While the 1,400-watt-powered, 15-inch Mackie Thump15Sv4 supplies enough low end to rattle the rafters and shake the floorboards of any club, its professional design matches brains with brawn for a subwoofer inspired by versatility and force. Showcasing a multi-voice High Pass Mode for ideal integration with your Mackie loudspeakers, you can tailor your low-end sound to complement the size of your speakers and venue, with a set of balanced Full Range and High Pass outputs as well as a variable crossover for further control. Fortified against transient spikes and thermal damage courtesy of Peak and RMS limiting, the Mackie Thump15Sv4 keeps the bass pumping and the party going, making it a permanent fixture in your gigging setup.

Hear and feel your music

The Thump15Sv4 boasts a 15-inch woofer powered by a 1,400-watt amplifier, capable of producing frequencies down to 27Hz for a response that’s felt just as much as it’s heard. Mackie’s Thump series of loudspeakers and subwoofers has long been among the most popular in Sweetwater’s inventory, and the Thump15Sv4 carries on this legacy. Indeed, it's among the loudest, lowest, and cleanest gigging solutions in its class.

Optimized for Thump loudspeakers

While the Thump15Sv4 is compatible with many PA systems, it performs best when paired with its Mackie Thump loudspeaker brethren. The Thump15Sv4’s multi-voice High Pass Mode bolsters the relationship, allowing you to dial in the ideal sub sound to complement your Thump 12, Thump 15, or Thump Go speakers. Additionally, Variable High Pass Mode lets you manually set your crossover, tailoring your low end to suit your system and venue. On that note, High Pass and Full Range balanced outputs, a variable Gain knob, and a Phase switch ensure that your low end is as focused and leveled as possible.

Designed for long-term use

Mackie clearly intended the Thump15Sv4 to go the distance, as evidenced by the thoughtful safety features it includes. First, Peak limiting catches potentially dangerous transient spikes that could cause your driver to become over-extended, thus preventing mechanical damage. Second, RMS limiting keeps your subwoofer’s temperature under control during multi-hour use, preventing the voice coil from overheating. Together, they ensure you get the signature Mackie sound every time you set up.

Mackie Thump15Sv4 Features:

  • Mackie’s esteemed Thump subwoofer, with a 1,400W rating, 27Hz–180Hz frequency response, and 132dB max SPL for plenty of oomph
  • Multi-voiced High Pass Mode lets you choose the best voicing to complement your connected Thump loudspeakers
  • Variable crossover plus High Pass and Full Range balanced outputs let you customize the sub to suit your system and venue
  • Variable Gain knob and Phase switch ensure that your low end is optimally leveled and focused
  • Peak limiting catches potentially dangerous transient spikes before they damage the sub
  • RMS limiting keeps your voice coil operating within its optimal range for consistent use
  • Integrated carry handles for easy transport
