Jensen Loudspeakers

Vintage Ceramic speakers are designed to sound similar to the Alnicos, and were first developed in the 1960s as a cost effective alternative to the Alnicos. The advantage of the ceramic speaker is its ability to handle more power as well as a player's front end pedal accessories. Vintage Ceramic speakers are recommended for all types of music, and sound best at loud volumes.

With tight low-end and clear, bright highs, the C15N speaker from Jensen responds to overdrive distortion with a gritty edge.
