Jensen C12/50 (N) 12" 16 Ohm Replacement Speaker

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.


The Vintage Ceramic Jensen® speakers were the heart and soul of guitar amps made throughout the 1960s and are still widely used today. The C10Q was one of the most popular ceramic 10” speakers for mid 1960s Fender® amps and continues to be a very popular and excellent choice today. The C8R was predominantly used in small practice amps throughout the 1960s.


Jensen® Vintage Ceramic speaker model numbers all begin with the letter C and are sometimes referred to as the “C” series. Next in the model number is the diameter or size of the speaker. Vintage Ceramics are available in 8, 10, 12 and 15 inch diameters. Following the size is a letter which designates the speaker power rating. For example, R (25 watts), Q (35 watts), N (50 watts) and K (100 watts).


Therefore a C12N speaker has a ceramic magnet, is 12” in diameter and is rated at 50 watts. After determining what impedance is needed, you are ready to choose your Vintage Ceramic speaker!
