1932 by Gilbert Briggs who soon established a reputation
as one of the most innovative loudspeaker engineers of
his generation. His company was at the leading edge of
an exciting new technology which was dedicated to
bringing the pleasure of music and entertainment into
people’s homes. As the technology advanced Wharfedale
gave many music lovers their first taste of High Fidelity,
mounting a series of live sound demonstrations which
excited the audio world and heralded the birth of the
modern hi-fi loudspeaker.

product, using high-quality components and state-of-the­art testing equipment to ensure consistency and high
performance. At Wharfedale we design and build all of our
