C 12 K

Speaker Description

While not strictly a vintage reissue, the C12K is the first design that Jensen developed in the early ‘90s. It is tonally inspired by the classic vintage ceramic Jensen, but with a substantially stronger voice, full bass and smooth top end. The C12K became one of the speakers of choice for Fender®, used in a myriad of world-selling models. Vintage tone with modern power handling and dynamics are the key virtues of the C12K.
