Who makes GPX electronics?

GPX is a brand of entry-level electronics that are manufactured by an original equipment manufacturer on behalf of the brand's parent company, GPX, Inc. While the manufacture of its products is outsourced, the design of GPX products is handled in-house.

GPX is headquartered in St. Louis, Mo. It was founded in 1971 under the name Dick Proctor Imports. It started using its current business model of using a network of OEM factories across Asia in 1973.
