Grundorf Corporation (pronounced grun-dorf) is an American loudspeaker manufacturer / road case company headquartered in Council Bluffs, Iowa, USA.
Grundorf Corporation was formed in 1984 to manufacture and repair audio equipment for regional and touring musicians. As the business grew and its reputation for producing quality speaker cabinets increased, audio companies such as Celestion began using Grundorf to design and build their systems.
As Grundorf continued its focus on Protective Case sales, a growing demand from touring groups like Manheim Steamroller for sophisticated, application-specific audio systems kept the company occupied.
Eventually, two complimentary divisions were formed: Grund Audio Design and Grundorf Case & Accessory.
Grund Audio Design Division GAD audio engineers in their fully equipped laboratory, use multiple techniques including LEAP, LMS, Thiele-Small parameters and industry audiophiles for critical listening tests. GAD systems employ cutting-edge materials including asymmetrical horns; Neodymium magnets; Titanium drivers; full-protection circuitry; Baltic Birch wood and third-order crossover networks to precisely match transition between drivers.
Grundorf Case and Accessory Division Grundorf Cases are built for a wide array of applications where portability and mobility are of prime importance. Their innovative and sturdy designs are widely used in educational facilities, corporate A/V, lighting, musicians, rental, DJ and “Pro-Audio” production companies. Their reputation is also built by “on-the-road” durability and ability to accommodate precise but often changing dimensions of almost any type and brand of equipment.
