Electromagnetic loudspeaker
Made of solid oak with sawn ornament. With direct drive "VEE" movement. The system has two coils positioned at 90 degrees angles forming the letter "V". This allows more movement of the cone and better reproduction of low frequencies, but also introduces some loss in sensitivity.
Sidney George Brown (1873-1948), the company founder, was a prolific inventor of electromechanical devices, including the well known "A" headphones, the "Microphone Amplifier" and a gyro compass. The company also made loudspeakers and radios. In 1906 he founded Telegraph Condenser Co and in 1910 he set up a business under his own name: S.G. Brown Ltd., in Watford (North of London) and later had an establishment in North Acton, London W3. The company eventually became part of the Racal organisation which in turn became part of Thales-Racal Acoustics.
