Wharfedale - SI 15BX

A little history ...
In 1932 Gilbert Briggs, advised technician, built his first wall in the basement of the family home in Yorkshire, specifically in Ilkley in the Wharfe Valley ("dale" meaning "valley"). He decides to sell the following year and opened its first workshop near Bradford to make it its loudspeakers in larger series.
The radio is experiencing a real boom prewar and small business subcontracting major brands, taking full advantage of this new trade.
The war brings its share of innovations in this field and demand is becoming increasingly urgent for products capable of reproducing sounds with the greatest possible fidelity (Here Radio London ...).
When peace returned, Wharfedale invented the first two-way speaker, with a ten-inch tweeter and a frequency divider (crossover), a technological innovation that would change forever the sound reproduction.
In 1958, Gilbert Briggs sells his business to Rank, but is still in control and always innovative (in particular using ceramic magnets) before taking a well-deserved retirement seven years later.
Since the 60s, the company is very interested in the market for hi-fi and produces tuners, amplifiers and even turntables turntables while maintaining its leadership in the manufacture of vessels. In 1992, merged with Wharfedale Mission to become Verity Group PLC and focuses on the sound for which the demand is huge, while marketing a range of pro loudspeakers for use by touring musicians.
