Product Details
Speaker, Jensen® Vintage Ceramic, 12", C12N, 50W, Impedance: 8 Ω
  • P-A-C12N-8
  • Sold individually

The C12N is one of the most important speakers in Jensen’s history. It is the top 12” speaker of the ‘Blackface Era, used by many American manufacturers in the mid ‘60s for their upper range models when the price of AlNiCo became unsustainable for the manufacturers. Clear highs, solid mids, and powerful basses, it epitomizes the tone of that decade, from the surf, the rock n’ roll, the electric blues and the West Coast inspired music. It was used in Twin, Bassman and Bandmaster style amps, and many others.

Guitarist Description: Smooth and straightforward, full bodied tone with high frequency chime. It responds to overdrive distortion with powerful mid bite.
