There was once an Englishman named H.A. Hartley, who was a contemporary of H.G. Baerwald, P.G. Voigt, P.K. Turner, and other men whose first two names are lost to us. Hartley was a capable designer and audio theorist, not to mention a gifted lecturer and writer—his literary achievements include a book on astrology (footnote 1), of all things—and he's often credited with coining the expression <I>high fidelity</I>.

The Hartley company made electronics and loudspeakers, the latter of which included full-range coaxial drivers using energized field coils and, later on, quite powerful permanent magnets—just like their countrymen at Lowther Loudspeakers, Ltd.
