Definitive Technology

Design and Development


For over a decade, GPD was Definitive Technology’s go-to loudspeaker design and development partner. For many of their product categories, we were responsible for much of the creative content. In some cases, we provided complete industrial and mechanical design for an entire product line. A rewarding body of work that garnered Definitive many industry accolades and helped them to become a major player in the U.S. audio market. These are some of our favourites!
