Boss Series — The Loudest Horn We Build for the M18 Platform

The Boss Series is the top of our Milwaukee M18 lineup, and it earns the name. Four precision metal trumpets and a high-output compressor push a genuine 150 dB — the kind of sound that carries across a parking lot, a trailhead, or an open lake. There is no air tank to fill, nothing to mount, and nothing to wire. Drop in an M18 pack you already own and you are ready.

Why It Hits Harder

  • Quad-trumpet 150 dB output: Four trumpets stacked for depth and reach — full-size truck-horn volume in something you hold in one hand.
  • Tool-grade build: A rugged, ergonomic power-tool-style housing that shrugs off jobsite and trail abuse.
  • True M18 compatibility: Works with every Milwaukee® M18 battery — from compact 2.0 Ah packs to high-output 12.0 Ah — with hours of triggering per charge.
  • Remote on demand: Fire it from up to 300 ft with the included wireless remote, or step up to the long-range remote for 2,000 ft.
  • Zero install: No compressor, no tank, no harness. Snap in the battery and pull the trigger.

Where People Run It

  • Tailgates & game day — own the lot
  • Overlanding & off-road — signal across trails and camps
  • Boats & marine — a loud horn with nothing permanently bolted on
  • Safety & signaling — 150 dB cuts through everything
  • Pure fun — no explanation needed
