Jensen Loudspeakers

Alnico speakers produce a sweet, warm, vintage tone. They sound best at low levels and are great for blues, jazz and mellow rock. Alnico speakers respond quickly, giving the musician a "one with the amp" feel. They are world renowned as the premium speaker with the best tone.

Alnico speakers are made with magnets containing aluminum, nickel and cobalt. They are often featured in print as "AlNiCo", symbolizing the three respective elements. Cobalt is difficult to procure these days resulting in Alnicos being the most expensive speakers in the Jensen line.

With warm, deep low-end and sparkling highs, the The P15N responds to overdrive distortion with a bright edge and lengthy sustain capabilities.
