Celestion made pioneering use of Laser Doppler Interferometry to analyse the cone behaviour of an original Celestion Blue. They could then form a precise model of the vintage speaker’s characteristics and apply it to a speaker design using new materials for greater power handling.
It was found that Celestion’s ‘H’ magnet came closest in performance to Alnico. This was partnered with a new cone and new coil assembly employing modern materials with similar mass and physical properties to the originals, but better able to handle the extra heat generated through operating with higher power equipment.
Seemingly twice as loud as anything else at the same power level, the Vintage 30 handles massive overdrive sounds with ease. Tight bass, fat mids and a smooth, harmonically rich top end have made the Vintage 30 an excellent 4 x 12 loudspeaker. Of course, it’s also suitable for any other cab!
