Jensen’s 15-watt P10R and P12R (shown above) alnico speakers, P10Q and P12Q (20 watts), P12N (30 watts) and a few other models played a big part in the signature sounds of great American ’50s amps from Fender, Gibson, Ampeg, Magnatone, Premier, Silvertone, and others.

In the United States, Jensen was the big name in (lower-powered) speakers in the 1950s and early ’60s, and, in the years after, the company retained a reputation as the hottest vintage American make to own. Lower-powered speakers, with all their gorgeous “flaws” became a big part of the rock and roll and blues sounds, and they have retained this role for more than 50 years. A lot of players who weren’t seeking absolute “clean clean” tone enjoyed the added grit, bite, edge, and compression that a touch of speaker distortion adds to the sonic brew.

Those they found, however, cost more than the lower-rated drivers, so even when available, they weren’t universally employed. As guitarists found themselves in bigger and bigger venues that required higher clean-volume levels, amp makers sought out more robust speaker designs.
