Ohms:

The AlNiCo P12N is surely one of the most iconic Jensen speakers of the late ‘50s. Visually impressive because of the big bell cover on the magnet, it is the highest powered 12” speaker in the range. Among others, the P12N was used in the high-end amps of the time such as the Fender® Tweed Twin. Crystal clear in the treble range with transparent mids and powerful but tight bass, it is the “King of Clean Tones”.

Guitarist Description
Very warm and full bodied tone with powerful mid-bite and sparkling highs. When presented with overdrive distortion it displays a bright and colorful crunch.

I have a Fender Hot Rod Deluxe Limited Edition that came with a Jensen P12N speaker. This speaker does wonders for the Hot Rod tone. I can't imagine having any other speaker in this amp and having it sound so good. I have so much trust in Jensen that I also plan to change out the stock speaker in my Champion 600 to a Mod 6-15.

I am a huge fan of the new Jensen's. By that I mean the whole series of reissue vintage models and the new products as well. I first became hooked by trying out the P12N in my 1954 Fender Deluxe. That was it! I was a fan from then on. It was like adding 10 watts of power along with more headroom and most importantly, the tone was right there. Perfect. Which is really what it's about, the tone.
