Since its formation in 1994, Hampshire (UK) based Clockaudio has achieved a position of high regard within the professional audio industry. The company's reputation has been built on sound principles; its dedication to quality and service has gained the respect of all those who have encountered its products and staff. Today, tributes and endorsements continue to precede Clockaudio into an ever-wider territory, helping the company to attract worldwide representation without the fanfare of its contemporaries. Audio Professionals now actively seek out and recommend Clockaudio for its reputation as a trusted, proactive and dedicated manufacturer, and for its recognised customer driven approach to audio solutions. Central to this is Clockaudio's in house research and development facility, which allows clients to explore customised prototypes and develop incredibly specific briefs in partnership directly with the manufacturer, often working to very short deadlines and in low volumes. This partnership approach has struck a chord with consultants and contractors alike, giving them the opportunity to become involved in developing the ideal solution rather than having to make do with the most suitable off the shelf item. This ability to customise is just one of the many factors which make the Clockaudio of today clearly different in a world of identikit manufacturers. Seventeen years since its inception, Clockaudio remains true to its founding principles - quality and service.
