Jensen Loudspeakers

Jensen Loudspeakers is a company that manufactures speakers in many different models and sizes. Originally located in Chicago, Illinois, the company built a reputation during the 50s and 60s providing speakers used mainly in guitar and bass amplifiers. Although the American company is long out of business, "reissue" guitar speakers are currently made in Italy by SICA Altoparlanti and distributed in the United States by CE Distribution.

The current Fender Twin Reverb amp uses two 12" Jensen C-12K speakers.

The former Jensen Radio Manufacturing Company was founded in 1927 by Peter Laurits Jensen, the co-inventor of the first loudspeaker, in Chicago, Illinois. The company gained popularity in its early years, rising to its peak in the mid 1940s when Jensen speakers were selected to be used in the first production of a guitar amplifier by Fender Musical Instruments Corporation. Subsequently, Jensen speakers in the 40s, 50s, and 60s became commonly featured in major amplifier production, including amplifiers produced by Fender, Ampeg, and Gibson. The company also produced Hi-Fi loudspeakers for home use and was a manufacturer of OEM drivers for other brands.

Jensen Loudspeakers ceased production of their products in the late 1960s. The speakers remained heavily sought-after as replacements for amplifiers originally manufactured with Jensen speakers. Following that demand, SICA Altoparlanti began reproducing "reissues" of the Jensen speakers in 1996. These speakers are designed to be as close as possible to their original design.

In 2008, SICA Altoparlanti began producing new speaker designs under the Jensen name. These speakers and the Jensen reissues are distributed in the United States by CE Distribution.

Jensen speakers used a model number that contained 4 to 6 characters.

The first character denotes the magnet type used.

These are listed in the order in which they were made, with the P line starting in the 1940s and the C line starting around 1960.
