12" equivalent of Jensen P10R

Jensen P10R is sort of low watt, so probably the Jensen P12Q. P12N is a tad higher watt.
Jensen keeps you in the American sounding ballpark. Lot of Great brit alnicos, but,
that is a diff spin. Wish you luck

 

If you can find a (now discontinued) Eminence 1228 (not the GB version) it sounds excellent. Have one in my 5e3. But, they are getting tough to find.

Maybe one of the Weber offerings? I'd say give them a call and see what they say.

I am not familiar enough with Jensen's 12" offerings to give you a good suggestion.

 

Why wouldn't the Jensen P12R not be the 12"sound equivalent? Both are alnico 25 watt speakers

 

Weber makes the best-liked, biggest line of Jensen equivalents. The literal equivalent of a P12R is the 12A100T, 15W nominal compared to the original's 12W nominal. This would sound most like an original if you ran a vintage OT and so on. Many people move up to the 12A125 series, 20-30W, somewhat larger voice coil, etc. It has a *lot* of choices of cone and other details. Definitely contact CJ at Weber and tell him what amp and what sound you're trying to achieve.

worth considering the Jensen neo speakers. I have a Tornado in a YGM3 and it's really nice, and lightweight!

 

The Weber Sig12AS is great up to medium loud volumes but gets pretty ratty after that. I'm using one in my 5A3 and it delivers that Vintage Tweed tone.

 

What don't you like about the sound, and are you sure it's the speaker and not other settings? Amp stand?

Regarding Jensens, the MOD (AKA Chicago ) sound, to me, rather good as a range. Not for everyone. The 12-35 is a good speaker up to medium/loud levels, i.e., keeping up with a fun band. When it does get driven very loud, i.e, a 15 Watt valve amp run hot with a fuzz in the mix too, it rats out. The 50 and 70 Watt models keep their composure rather better, but if skrank is your desire, the 35 Watter may fit. They're not the most efficient speakers either, so you get to turn your amp up more.

The Jet Falcon is altogether smoother and more efficient. Drive that with 15 Watts of clipping valves and it doesn't get in the slightest ratty.

 

The equivalent would be the P12R

 

Why don’t you like the GB128? I have one coming Thursday.

I happen to have 2 vintage 60’s or 70’s (haven’t checked the serial number for year of production) P12R’s (8 ohm). Was going to put in a 2x12 but might put just one in my my 74 Princeton Reverb. If you are interested in the other, we might be able to work something out.
Good Luck

 

A couple thoughts:
What is the depth of the Mojo cab? Deeper cabs make a big difference.
Also, how thick is the mojo baffle? If they are using 3/4" that has an effect like you mention.
I'm not a fan of the Sig's myself. .. or the P12R for that matter. But if you liked the P10R, then a weber P12Q (12A125) or similar might work for you.

 

I have a Pro Junior IV w/P10R it's a great combination. I've always dug the reissue Jensen P10R's
