Brief Product History Cont.
As we've said Arthur Radford's other love in hi-fi design was for loudspeakers. In 1965 he teamed up with A.R. Bailey who had carried out preliminary work on a project that was eventually to be known as 'The Transmission Line Enclosure'.
This wasn't what it was first called, however. The revolutionary design for 'A Non-resonant Loudspeaker Enclosure' first saw the light of day in Wireless World, October 1965. In this article, shown below, Bailey outlined a speaker enclosure that eliminated the main cabinet resonance modes by using an acoustic transmission line model.

Together with Radford the 'Transmission Line Enclosure', as Bailey later named it, became the backbone of all Radford High End speakers as shown in a page from a Radford speaker brochure pictured on the right, above.
