User Reviews

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!!

Sal

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!

Randall

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.

Pierre in Eau Claire, WI

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.

Michael in Medford, OR

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!

Lefty in New Hampshire

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

Geoffrey in Sacramento, CA

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.

Chris in Williamsville, New York

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