DeWalt Air Horn Attachment Setup

If you’ve been looking to add serious power and fun to your tool collection, the DeWalt Train Horn is the ultimate upgrade. Whether you want a ready-to-blast model straight out of the box or prefer to build your own from scratch, there are two ways to get your hands on a DeWalt Air Horn setup — and both options deliver the unmistakable 150dB roar that BossHorn is known for.

Option 1: Buy a Ready-to-Use DeWalt Train Horn

This is the fastest and easiest way to experience the power of a DeWalt Train Horn. Each unit is handmade from a brand-new DeWalt impact driver and fully assembled, tested, and ready to blast. There’s no installation or wiring required — simply attach your DeWalt 20V battery (OEM or aftermarket), and it’s ready to go straight out of the box.

Every model includes a built-in air compressor, metal trumpets with a powder-coated finish, and a remote control system that lets you trigger the horn from up to 160 ft away (and up to 2000 ft with a long-range remote). You can also use the original DeWalt trigger for manual activation, making it both convenient and authentic.

Available Variants:

• Extreme Series – The loudest version, with unmatched power and projection.
• Quad Trumpet Series – Strong, rich sound and a perfect balance between power and portability.
• Dual Trumpet Series – Compact, lightweight, and still impressively loud.

All three variants use the same compressor and electronic system — the only difference is the number of trumpets and overall sound intensity. Just plug in your battery, and it’s ready to blast.

Option 2: Build Your Own Using the DIY Kit

If you love to tinker or want to save a bit of money, you can build your own DeWalt Train Horn from an old or used impact driver or drill. To do this, you’ll need our DeWalt Train Horn DIY Kit.

This kit includes all the essential components — the air compressor, trumpets, control board, remote receiver, and hardware — everything except the drill body itself. You’ll use your own DeWalt impact driver (or another compatible drill body) as the base. Assembly usually takes about 2 hours, but the exact time depends on your skill level, tools, and experience.

It’s a fun project for anyone who enjoys working with tools and electronics. When you’re done, you’ll have a fully functional DeWalt-powered train horn — built by you, customized your way, and every bit as powerful as our ready-made models.

Which Option Should You Choose?

• If you want a ready-to-use solution that works instantly and guarantees perfect results, choose one of our pre-assembled DeWalt Train Horns.
• If you want to build something yourself, enjoy DIY projects, and save some money, grab our DIY Kit and use your own drill body.

Either way, you’ll get the same BossHorn power, same 150dB train sound, and same high-quality craftsmanship. Every setup works with a DeWalt 20V battery, and every horn can be triggered both by the tool’s trigger and by a wireless remote control.

The Bottom Line

The DeWalt Air Horn Attachment Setup gives you two paths to the same epic result: either buy a fully assembled model that’s ready to blast, or build your own using our DeWalt Train Horn DIY Kit. Whether you’re after the raw convenience of a prebuilt horn or the satisfaction of crafting your own, one thing is certain — when it comes to sound power, nothing beats BossHorn.
