Mackie Thump18Sv4 – 1400 W Powered 18″ Subwoofer for Live and DJ Use

The Mackie Thump18Sv4 is a 1400 W active 18-inch subwoofer built for DJs, bands, and event crews who need serious low-end weight under their PA. Reaching 25 Hz and 132 dB peak SPL with selectable high-pass modes and stereo XLR I/O, it delivers the floor-shaking impact electronic music, hip-hop, and full-range live shows demand — available at Soundium.

Key Features

  • 1400 W Class-D amplification: 132 dB peak SPL with deep, dynamic headroom.
  • 18″ high-performance woofer: Pressurises rooms with response down to 25 Hz.
  • Selectable high-pass modes: Thump 12, Thump 15, Thump GO, and Variable (80–160 Hz) for one-knob 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, stereo full-range outs to chain extra subs.
  • Phase invert + stereo/mono summing: Quick adjustments for cardioid stacks or single-sub setups.

Customer Benefits

The 18″ Thumpv4 sub is the heavy hitter of the lineup, designed for the room sizes and material that demand real sub-bass extension. The DSP modes and alignment delay take the guesswork out of crossing over to your tops, while built-in handles, an M20 pole socket, and a defeatable LED keep load-in fast and the front panel clean.

What's in the Box

  • Quick Start Guide

Use Cases / Ideal For

Mobile DJs, club nights, mid-sized live bands, weddings, festivals, corporate events, and any production where the low end needs to reach down and out — not just polite reinforcement.

Compatibility

Designed to pair with Mackie Thump12v4, Thump15v4, and Thump GO mains via dedicated HP modes. Variable HP works with any third-party tops between 80–160 Hz. Stereo full-range outputs let you daisy-chain a second Thump18Sv4 for serious low-frequency arrays.

Pros & Cons

✅ Pros:

  • Reaches 25 Hz with authority
  • Plug-and-play crossover modes for Thump tops
  • Stereo I/O streamlines cable runs
  • Defeatable LED for low-profile use

⚠️ Cons:

  • Single 32 kg cabinet — two-person lift is wise
  • Overkill for very small rooms; Thump15Sv4 may suit better there

The Mackie Thump18Sv4 is the heaviest hitter in the Thumpv4 family, turning a compact PA into a full-range, club-ready system — available at Soundium.
