The 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 - Audio Products for Discriminating Professionals
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.

With years of on-the-road experience, the common-sense cabinet-design team also takes advantage of Grundorf’s Fabrication Specialists. Benefits beyond audio quality are reduced set-up/tear-down costs and efficient truck packing. The very competitive pricing becomes even better by flexible ordering of accessories on the units.

Grund Audio Design speaker systems carry a 5-year limited warranty.

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 houses of worship, 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.

Grundorf’s highly-mobile Combo Cases are in great demand in dual-purpose rooms. These locations include churches, gymnasiums, cafeteria/auditoriums, educational institutions, city council chambers, corporate board meeting rooms and other temporary meeting facilities.

Grundorf has introduced many innovations:

Grundorf’s Fabrication Specialists take advantage of “Dado” and “Rabbet” joinery, continuous hinges, pressure fitting panels, 4 laminate colors, 2 carpet colors, multiple powder coat type finishes and Baltic-birch wood.
