This is a great speaker for a 5F1 Champ. I built a 5F1 with a slightly bigger cabinet to accommodate a 10" speaker. The P10R does an excellent job: clear and clean but still round and warm. For such a small cabinet I am impressed with the amount of bass response - I did not expect that from a 10" speaker in such a small cabinet. There are lots of comments on the internet stating that the modern Jensens sound shrill and brittle but I did not experience any of that. Quite the contrary: warm, round and with a pleasant old school vibe is how this P10R sounds in my little Champ! In spite of the relatively low sensitivity, the amps is also surprising loud, which I ascribe to the good mid-response of the speaker, which gives it a good audible voice.

I used for a long time 12 inch speakers, Jensen as well as Celestion. Jensen stays my favorite speaker. Celestions sound muddy around the 160 -200Hz, and this is not the case with Jensens speaker. I use mostly the Alnico P10R only for the typical Alnico sound. When I tried the C10R , I very surprised how good they sound. Bass notes are much cleaner with 10" speakers. Now , Celestions are collecting dust. Jensens for ever.

Bought these to replace the four tired CTS 137-735 speakers in a '67 Fender Blackface Super Reverb amp that was recapped in 2007. These new Jensens sound very close to the CTS speakers and will only get better after break-in! Have experience with these P10Rs in three other amps and they sure didn't disappoint...very happy!

I compared these new Jensen P10R's to some vintage 1959 P10R's I had in my Fender tweed amp collection (Deluxes) We A & B'd them against the vintage P10R's and they sound IDENTICAL to the 1959 Jensen P10Rs!! Just what I wanted, good high end without sounding thin or harsh and a big tight bottom that only alnico can deliver...just an amazing speaker!! I put a set in my blackface 1965 Super Reverb and they sound incredible. Thanks Jensen!!

I built a deluxe reverb 2x10 combo and loaded a mix of the Jensen P10Q and the P10R together. All I can say is WOW... That has got to be the best combination of alnico speakers I have ever heard in my life!

I bought a pair of P10R's for a friend's Vibrolux as payment for a drill press I bought from him, I liked the sound so I bought a pair to go with my Fender Vibrosonic and my Peavey Delta Blues 210 and they sound great.

I purchased 4 P10Rs to put in a custom cab I built to reproduce a Bassman sound. I used some 40 year old pine I had in the garage and modeled it after my 59 Fender Pro. The sound quality is superb and just what I was looking for and the final cost was very reasonable. I'm thinking about building a 1 x 12 cab next.

I am pleased to say that my choice of a Jensen P10R and a P12R Alnico speaker return the 44 year old Gibson GA-30RVT to its formal glory. The Jensen Vintage speakers give a very rich and warm sound, exactly what I was looking for, Thank You!

I am currently using two P10R alnico speakers in my 1971 silverface Fender Super Reverb. The Jensen speakers deliver the bright vintage tone I had been looking for. Thanks, Jensen Speakers

I’ve modified a 1971 Bogen 10watt class A tube PA amp, now I’m putting the cabinet together. The thing sounds great with the P10R. I love the sound, the speaker is definitely what I wanted for this. I play an Electric mandolin, this is a big improvement.

I am collecting parts to build a Fender Bassman clone and will use P10Rs - they are my favorite speaker.
