Speaker - Jensen® Vintage Alnico, 10", P10R for Fender®, 25W, 8Ω
Not a strict reissue, the P10R-F was born as a special edition of the P10R, developed in cooperation with Fender®, for the Custom Shop ’57 BandMasterä and the 20th Anniversary Vibro-Kingä amps. By means of a different cone membrane, the P10R-F has a warmer, ‘aged’ tone, and breaks up in a sweet, progressive manner. A very unique speaker for true Tone-Connoiseurs.
Guitarist Description: Warm, mellow tone with less bite and brightness than the standard P10R. In overdrive, this one eases into a creamy distortion.
- Lows: Loose
- Mids: Subdued
- Highs: Subtle
- Overdrive: Crunchy

I an going to buy an old vibro king that I want to sound like a vibro king 20th anniversary. Are these the ones to buy? And what impedance should I use for a vibro king? Thank you!

These are the speakers used in the 20th anniversary Vibro King. You would want to consult an owners manual or schematic for your amp's impedance.

With the AlNiCo P10R, does the bass still "flub" at maximum volume as the stock ceramic speaker (C10R) does in a Fender Princeton 65 Reverb Reissue? Would going to a 40 watt rated power from a 25 watt help with the "Bass Flubbing"?

The low end on the P10R is going to be loose as well as the 40 watt P10Q. Please visit the tone generator to have a Jensen rep help you find the right speaker. https://www.jensentone.com/tone_generator.
Product Reviews
Wanted to tame the highs in my Fender Pro Junior IV with a different Alnico speaker.
The challenge was the depth of the cabinet, and the P10RF is the same size as the original P10R.
It did tame some of the high-end in the amp so mission accomplished.
Great speaker. I put it in a 68 Custom Princeton Reverb that breaks up on it's own pretty early. I wasn't sure if it was the right for the amp at first but after two weeks of playing it sounds a lot better. So it does need time to break in. This speaker is good for a smooth 50s-60s tone for playing and recording at home when you want early break-up. Probably not ideal for a band if it's your only speaker unless you're doing really raunchy blues. Not sure how much different this is than the regular p10r but it looks cooler.
