Changing your speaker will make the biggest single most dramatic improvement in your sound. At Watford valves we stock the drivers that can help you find the tone you are looking for.


Alnico magnets are made from a combination of aluminium, nickel and cobalt used to make the magnets. The speakers were common in amps made in the 1940 through to the late sixties. The Alnico speakers have a rich warm overdrive sound. They are famous for the early speaker distortion with touch sensitive response. They have a large dynamic range and long life with a bright tone.


Ceramic magnet units tend to provide higher power handling at a lower cost than alnico magnet units. They produce a sound which is generally considered harder with more punch and aggression. They are considered less sweet than the alnico whist providing greater clean headroom.


Neodymium magnet speakers offer the fastest cone response of any magnet material. The speakers retain some of the sonic benefits of the alnico magnets but offer high power handling with very low weight.

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.
