he and Allen founded Boothroyd Stuart Meridian (later Meridian Audio Ltd). They designed, manufactured, and sold the entire product range themselves, with very little investment. Allen and Bob received their second Design Council Award for the company's 100 Series in 1982. In 1986, a new line – the 200 Series – was launched and continued to be produced until 1993 when it was replaced by the 500 Series. It grew to include the whole range of domestic hi-fi, from CD players, radio tuners, pre-amplifiers, power amplifiers, digital-to-analogue converters, and a range of multi-room components, all designed by Bob and Allen. A series of active loudspeakers (with on-board amplifiers) was developed and brought to market starting in 1977. By this time, Meridian Audio had become known for its state-of-the-art electronics, distinctive design style, and corporate identity. In 1988, Bob and Allen were presented with another Design Council Award by the Duke of Edinburgh, becoming the first design team to win this award three times. In 1991, Allen founded his own consultancy, Cambridge Product Design Ltd., offering one-stop design solutions, which he ran from his home in Little Shelford. Early designs included a new class of loudspeaker for Canon, the first Patientline (providing a phone/TV/Radio console for hospital patients), the Aga Masterchef range cooker, a coffee machine, timpani drums, and different types of loudspeaker for KEF, Celestion, THX, Russound and Pioneer. He continued as design director of Meridian Audio. Pioneer commissioned Boothroyd to produce a unique appearance for its new surround-sound speaker system. His design was used in the Pioneer Elite Reference speaker system. Recognition and later life Allen was elected Fellow of the Royal Society for the Encouragement of Arts, Manufactures and Commerce and the Royal Society of Illustrators, Artists and Designers. Allen's semi-retirement provided time for him to indulge his hobbies: drawing and painting, tennis, golf, and music. From the 1990s, he would always take his sketch pad on holiday and took pleasure in sitting in front of a historic building or view that captured his imagination. He was instrumental in the fundraising and design for a new village hall in Little Shelford and created the elegant village sign. Later on, he led sessions of the Pavilion Art Group, helping artists to develop their skills. Listening to music was always an important part of Allen's life – in particular classical, jazz, and popular music. Allen was diagnosed with advanced prostate
