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”.
Whoa man this speaker is truly awesome. I picked up an old reconed vintage P12n and swapped it into my fender blues junior III - truly the best thing to do on that amp started with swapping reverb tank, then mods, and bigger trannies, then a Mojotone Deluxe Tweed pine cabinet and now the Jensen .. Wow Junior woke up ... that little amp came to
life .. like lifting a blanket off ...
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.
Yeah I've been trying out the different Jensen Mods and they are fantastic. I talk them up all the time. A buddy of mine put one in an old Vox amp and it's amazing. I really think they are the best bang for the buck out there. I also have a tweed Hot Rod Deluxe with the Jensen P12N which is also great
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.
