The P10R is very important in the history of Jensen speakers. Its shimmering, yet throaty and vibrant tone is one of the signatures of the Tweed era and inspired the start-up of the British tones. It was the first speaker reissued by Jensen, presented to a restricted panel of partners at the 1999 Summer NAMM show. The P10R is the speaker that contributed to the magical tone of the 4x10 Bassman® Tweed amps, the 4x10 Super Tweed Amps and the equally mythical 3x10 Bandmaster® amps.
Guitarist Description: Rich, warm tone. Accentuates the higher frequencies in sparkling detail.
- Lows: Loose
- Mids: Firm
- Highs: Smooth
- Overdrive: Crunchy

A have a new reissue Custom '68 Vibrolux Reverb (ca. 2014) and I want to replace the Celestion speakers with Jensen Alnico P10Rs. Since there are two speakers, do I still order them in 8-Ohms? Thanks.

The '68 Custom Vibrolux Reverb calls for a 4Ω minimum, and appears to have two 8Ω speakers wired in parallel, so yes, that should be correct.

I put this in my early 70's Champ...whoa mama! Had to offset it and cut the baffle to get it in the little cab but totally worth it. Great low end response and loud and proud sound. Great speaker, but you all already knew that, right??!
It's hard to imagine a speaker making such a difference in the performance of a tube amp. I have a '68 Custom Vibrolux Reverb which, I've been told, began production around 2014. It's a well-made amp, but it didn't really impress me like my original '68 Vibrolux did (CBS-Hybrid). The original stock speakers were Celestion G10R - 30s...very bright and a little shrill-sounding with muddy and over-exaggerated basses. I'm a solo-Jazz Guitarist primarily and wanted a vintage, clean sound so I chose the Jensen Alnico P10R. As you may know, the Vibrolux utilizes 2 - 10" speakers and I had my service tech install them for me yesterday. I could not believe the difference. Clean and smooth highs and mids with tight/clear basses - exactly what I was looking for - with a little extra "punch" to each note! I play an archtop acoustic guitar with a vintage DeArmond #1100 "Rhythm-Chief" pickup. The sound with these Jensen Alnico P10Rs is simply fantastic. Not surprising, since I've read that Jensen was the original amplifier speaker for many companies from the very beginning - including Fender. I'm 100%+ satisfied. Thank you, Amplified Parts and Jensen for making these speakers available for the discriminating musician with a discerning ear for quality...Bravo!
I used the Jensen speaker from Amplified Parts to replace the speaker in my Fender Super Camp X2.
The upgrade turn out very well with a greatly improved sound!
Thanks,
Allen
These speakers came stock in my Super Reverb Reissue. I have never had need to replace them, they provide all the warm clean tones I need, and have that magic sparkle. Driven hard, they crunch nicely, never "farty" on the low end.
I agree with Ross - these speakers are a solid replacement. My amp tech recommended that I replace the CTS speakers that were stock in my vintage Super Reverb. I will admit that I was a little hesitant to mess with the original speakers, but the P10R has really livened this amp up. Highly recommended.
I have these in my Fender Super and they just sound so sweet, and I was watching the Super and see that Pete Townshend uses the the Fender Vibro King amp that uses these as well, what is good for Pete is good for me!
