Editor, publisher and company founder, Ed Dell, began in 1970 with a quarterly publication called The Audio Amateur. His mission then was to provide quality projects for those who find deep satisfaction from crafting electronics and speakers with their hands. What developed over the next 30 years was the building of an author-base over 700 members strong. Technically superior to the "review" publications, Audio Electronics (formerly Audio Amateur) and its subsequent spinoff magazines, Speaker Builder and Glass Audio provided a forum for some of the best known names in the world of audio design. Sporting contributions by Erno Borbely, Nelson Pass, Joseph D'Appolito and even Mir astronaut, Norman Thagard, the pages of Dell's publications have served generations of audio constructors, designers and enthusiasts.

With the advent of the new millennium, the mission of Dell's newest publication, audioXpress (the continuation of Audio Electronics, Speaker Builder and Glass Audio) remains clear. To support and nurture, to educate and entertain, to delight and challenge the current audio constructor and the enthusiast of the future. Built to provide content in all areas of audio (mimicking the original Audio Amateur), audioXpress provides a wealth of information, projects and reviews every month.

Along with the audio enthusiast, Audio Amateur Inc. has also served the audio industry through Voice Coil, the monthly periodical for the loudspeaker industry and with two annual directories, The Loudspeaker Industry Sourcebook and The World Tube Directory. Acknowledged for its coverage of the field and the ability to provide industry information and technological developments, Voice Coil is unique in its focus. Complemented by the annual directory, the qualified readership is served a product designed to keep them informed and up-to-date.
