Born in 1946, Bo Bengtsson originates from the university town of Uppsala,Sweden. His father, an accountant, served as chief conductor for several choir groups which gave Bo early exposure to music and developed his musical interest.At 16, Bengtsson joined a local philharmonic orchestra as a cellist and later formed a trad jazz orchestra, this time playing double bass. He also sang tenor for various chamber choirs for the next 16 years.
While acquiring his degree in electronic engineering he opened a retail business selling audio components, and began developing his own loudspeakers. Shortly thereafter he worked with the Swedish representatives for Marantz, training their 800-member retailer sales force. Dr. Amar Bose happened to be in Sweden during this period, heard of Bengtsson’s loudspeaker work and offered him a guest scholarship to MIT. Instead, Bengtsson sold his share of the business and created a loudspeaker development and manufacturing company. He also was a contributing editor to various Scandinavian audio magazines, and taught physics. In addition, he occasionally made recordings for chamber choirs, and was president of the 150-member Swedish Product Developers’ Association. Bengtsson’s initial patented loudspeaker, CM3, was the first speaker to reproduce a true square wave anywhere between 250Hz - 2kHz. These transmission line speakers utilizing the famous Decca Kelly Ribbon unit sold more than 24,000 units.
Simultaneously, Bengtsson in collaboration with a construction engineer at the University of Uppsala, manufactured a transformerless high voltage tube amplifier for the Quad electrostatic speakers midrange/treble panels. Bengtsson's company was one of the few to use direct coupled high voltage tube amplification technology. Bo's gigantic Megatrend, a huge dipole loudspeaker, won prestigious awards and the praise of the late double bassist Red Mitchell (also an electronic engineer) who bought a pair of Megatrends, saying he had been searching for 15 years for speakers which could reproduce double bass faithfully. Bo is currently working with Mark Levinson and Red Rose Music, bringing new ribbon speaker technology to the music world |
