Built Around Four Tuned Trumpets
The Quad's spec sheet starts with its horn count. Four tuned metal trumpets move more air than any dual setup, producing a full 150 dB with the width and depth people associate with an actual locomotive. Behind them sits an efficient compressor that keeps every blast as strong as the first, and the whole assembly draws its power from a single Bosch® 18V pack — cordless, tankless, and light enough to carry one-handed. Sized and gripped like a cordless drill, this battery powered air horn goes wherever the day does. Each unit is handcrafted, and there is nothing to configure: seat a battery, and the horn is live from the trigger or the 160 ft remote.
Where the Quad Earns Its Spot
Numbers like these translate directly into range and presence. Fire it from the stands when your team scores and the whole stadium knows. Open a graduation announcement or convention keynote with a note nobody talks over. Keep it in the boat, the side-by-side, or the camp box as a signaling tool that carries far beyond shouting distance when it matters. And yes — as a prank, 150 dB from four trumpets gets a reaction every single time. Point it away from people and pets, and use hearing protection up close.
