Mackie Thump15Sv4 – 1400 W Powered 15″ Subwoofer for Mobile PA

The Mackie Thump15Sv4 is a 1400 W active 15-inch subwoofer designed to extend the low end of any Thumpv4 system or compact PA rig. With selectable high-pass crossover modes, phase invert, and stereo XLR I/O, it slots cleanly under main loudspeakers and gives DJs and live engineers floor-shaking impact without complicated setup — available at Soundium.

Key Features

  • 1400 W Class-D amplification: 132 dB peak SPL with deep, controlled output.
  • 15″ high-performance woofer: Reaches 27 Hz for chest-thump on kicks, basslines, and movie LFE.
  • Selectable high-pass modes: Thump 12, Thump 15, Thump GO, and Variable (80–160 Hz) for instant tuning to your tops.
  • 1.4 ms alignment delay: Phase-coherent integration with Thumpv4 mains across all HP modes.
  • Stereo XLR I/O: Stereo XLR inputs, stereo high-pass outputs to mains, plus stereo full-range outs for chaining additional subs.
  • Phase invert + stereo/mono summing: Dial in placement quickly, even in tricky rooms.

Customer Benefits

The Thump15Sv4 makes adding low end to your PA a one-cable job: pick the matching HP mode for your tops, plug in the mains' XLR feed, and the sub takes care of the crossover and time alignment. Built-in handles, an M20 pole socket, and a defeatable front LED keep transport, setup, and discreet placement quick on the gig.

Use Cases / Ideal For

Mobile DJs, small to mid-sized live bands, weddings, corporate events, and any portable PA that needs to extend its low-frequency response without scaling up to a full subwoofer rig.

Compatibility

Designed to pair with Mackie Thump12v4, Thump15v4, and Thump GO mains via the matching HP modes. Variable HP works with any third-party tops in the 80–160 Hz crossover range. Stereo full-range outputs allow daisy-chaining additional subs.

Pros & Cons

✅ Pros:

  • Genuine sub-bass extension to 27 Hz
  • Plug-and-play HP modes for Thump tops
  • Stereo I/O simplifies cabling
  • Compact for a 15″ powered sub

⚠️ Cons:

  • Single sub plus stereo tops needs a mono summed feed for best results
  • Larger sub (Thump18Sv4) is needed for very low electronic music or larger rooms

The Mackie Thump15Sv4 is the easiest way to add proper low end to a Thumpv4 or other compact PA, with smart DSP doing the heavy lifting on integration — available at Soundium.
