Celestion T3904 Vintage 30 Classic Series 12"/60W Speaker 16ohm Ceramic Magnet

We made pioneering use of Laser Doppler Interferometry to analyse the cone behaviour of an original Celestion Blue. We 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.
