History

Earthworks Audio was founded in 1995 by famed audio engineer David Blackmer. After David sold the legendary dbx company to BSR in 1979, he stayed on as a consultant for a few years before moving his family to rural New England. At that time, he had no intention of starting yet another revolutionary Pro Audio company. But he was driven by the idea of bringing the intimate experience of live acoustic sound to loudspeakers. As he tested tweeters developed by different manufacturers his ears began picking out qualities that were not represented in their specifications. This led him down a path of exploration; trying to understand what our human physiology is capable of hearing and looking to meet those needs in full with better technology. Today we are still building on the foundation of David’s human-centered approach to audio. Earthworks is based in Milford, New Hampshire.
