Great Plains Audio was born out of the Altec Lansing corporation in 1998. It carries forward the loudspeaker design and manufacturing tradition that began with Western Electric in the early 20th century. Great Plains Audio is the only place where the legendary Western Electric/Altec Lansing sound reproduction technologies live on.
We provide a wide array of professional grade loudspeaker components, including compression drivers, crossovers, and other transducers. Each component is carefully and meticulously handcrafted in the United States in our factory in Oklahoma City, Oklahoma. When you purchase components or repair parts from Great Plains Audio, you can rest assured that they are among the best in the world.
Great Plains Audio continues the Western Electric/Altec Lansing tradition of providing the best available sound reproduction devices that are demanded by both professionals and audiophiles worldwide.
Our famous 604 DUPLEX has been a favorite of recording studios and engineers since its inception in 1946. Over the years we have continually refined the 604 to meet the demands of digital and high definition audio. This is why it remains at the pinnacle of audio reproduction systems.
Dedicated to getting the best possible sound out of a digital audio, Computer Audio Design (CAD) is based in London, England. We are proud to introduce to the USA CAD's world-class digital source components alongside CAD's innovative Ground Control noise reduction devices.
