Kahlenberg Industries
<p>Since its founding in 1895, Kahlenberg Industries has earned a distinguished reputation as one of the world's leading manufacturers of sound signaling equipment. Established over 130 years ago by the Kahlenberg Brothers Company in Two Rivers, Wisconsin, the company continues to operate from the same building where it all started, maintaining a proud tradition of American manufacturing excellence.</p><h3>Engineering Heritage and Innovation</h3><p>In 1930, during the Great Depression, William Kahlenberg's son Roger developed the first Kahlenberg Air Horn, launching what would become the company's signature product line. Today, Kahlenberg Industries is ISO 9001-2015 Certified for the design and manufacture of sound signaling equipment, marine propellers, and custom metal products. The company operates from a 45,000-square-foot facility equipped with advanced testing capabilities, including a certified fully anechoic sound test chamber with equipment capable of finite frequency analysis and sound pressure level testing to over 150 decibels.</p><h3>Marine and Industrial Expertise</h3><p>Kahlenberg's engineering prowess extends across multiple industries. All Kahlenberg marine sound signaling equipment is certified to USCG/IMO requirements for frequency and decibel level, making their products trusted choices for commercial vessels, military ships, and luxury yachts worldwide. The U.S. Navy specifies Kahlenberg electric piston horns for aircraft carriers, demonstrating the military-grade reliability built into every product.</p><p>Beyond marine applications, Kahlenberg manufactures industrial warning systems and mass notification equipment. Their mass notification horns are used in coal yards, chemical plants, refineries, open pit mines and industrial facilities as well as in public spaces such as campuses and golf courses. The company provides air and electric horns for mass notification that cover areas up to 10 miles in diameter from a single source, showcasing the power and range of their signaling technology.</p><h3>Quality and Recognition</h3><p>Kahlenberg's commitment to quality has made them a household name in unexpected places. Chicago Blackhawks owner Bill Wirtz liked the sound of his yacht's Kahlenberg horn so much in the 1970s that he installed one in the arena, starting a tradition of sounding the horn after goals that became a leaguewide tradition. Today, Kahlenberg creates horns for yachts, commercial vessels and almost every NHL arena in the league.</p><p>The company's longevity speaks to its dedication to craftsmanship. Kahlenberg employs a skilled and dedicated workforce, with the average employee being with the company for over 11 years. This experience and institutional knowledge ensure that every Kahlenberg product meets the exacting standards that have defined the brand for more than a century, delivering reliability and performance in the most demanding applications.</p>
