Celestion speakers started in Hampton Wick England in 1924. Celestion Radio Company and Celestion Limited were formed in 1927, and two years later the company moved across the Thames to Kingston. The company grew rapidly, but was hit by the depression.
Wartime restrictions forced Celestion and the nearby British Rola Company to produce loudspeakers to the same specification; British Rola bought Celestion in 1947 and formed Rola Celestion and moved production to Thames Ditton in 1949. Rola Celestion was bought by Truvox - a manufacturer of public address systems in 1949.
Celestion developed the first dedicated guitar speaker T0530, what came to be known as the Alnico Blue and with its marriage with the Vox AC15 and AC30 a legend was born. In 1968 the company started production in Ipswich, moving all production there by 1975. Celestion developed the speakers that then powered the Blues and Rock Revolution in the late 1960's and early 1970's with speakers such as the G12M Green Back and G12H. Over recent years Celestion have remade some of their finest and most sort after speakers.
Watford Valves have supplied speakers to the music industry for over 25 years and with the benefit of hindsight can honestly say that for guitar or bass Celestion's are the best speaker's money can buy.

Original G12M 67 Celestions are very sought after for their attack and crunchy overdriven tone. Power chords and solo has a vibrant smooth woody and warm roundness and they retained the brightness and punch necessary to cut through the rest of the band.
Its highly articulate nature made this the perfect for the pioneering lead guitarists Such as Eric Clapton. This may have been the speaker used on Claptons solos on the John Mayall Bluesbreaker Album or Beano as it is known. Some musical historians feel it is likely that these would have been in the Bluesbreaker combo that Eric Clapton used on these famous sessions due to the speaker higher power handling over the Blue, Blue or Greenback the Jury is still out.

The cones material properties changes tonally over time so the cones were manufactured to replicate this. The originals magnetic flux and the demagnetisation also changes over time and Celestion replicated this. The result was a perfectly aged and sounding replica of this iconic speaker and made, like the originals in England.
