Tex.. this flies in the face of 90% of all critism of SICA/Jensen RI's that ive read. Most say the Jensen RI C12Ns have a harsh treble bite on the top end. So you think Jensen RI's are woofy and harsh without being bright?.. I don't hear it...Well if the EQ could universally save the day we would only need the one speaker, wouldn't we? There are different kinds of low end and highend, you know. Strangely the RIs tend to sound garbled without being very woofy and potentially harsh without being particularly bright, in my experience. It's supposed to be bright, really, so that you wouldn't want to turn down the treble other than for taste.
When it comes the Jensen RI C12N.. IMO after they get broken in they sound extremely close to the originals.. (I have some originals.. and I'm not alone in my assesment, there are other internet source that say as I) But!!!! I'll add so do Weber's 12F150s and WGS G12Cs.. All three sound really close to the originals.
It's all what one prefers...
I think it's the speaker snob splits hairs over the fact Jensen Ris have a voice coil of 1.472″ inside diameter, 1.125″ form length, .375″ windings width, 8 ohms vs the #6969 seamed cone vintage Jensen VC w/ 1.522″ inside diameter, 1.0″ form length, .375″ windings width, 8 ohms. or....... # 8220 unseamd cone VC w/ 1.522″ inside diameter, 1.25″ form length, .437″ windings width, 8 ohms.
The SICA/Jensen RI C12N is a mixer of both vintage models; It has a thicker voice coil than both vintage models: it has the same coil windings at the #6969 and the same form length as the #8220
Splinting hairs is what T Weber did... and a bunch of people bought into it because he chumed it up with on the phone. A+ for customer service.. F for being bias and splitting hairs...
Let me point out... The SICA Jensen RI has the same outside measurements of 12″ outside diameter, 3.33″ deep, 1.5″ voice coil opening as the originals Jensens...
So the one real difference: Sica/Jensen RI has a modern voice coil that is thicker which created a design change in the cup spider and the dust cap.... With the original Jensen designs : "Were they not prone to the voice coild frying out from heat?" I do believe so... For all we know SICA had this VC already in a few speakers and it was "tried and true" and went with the design.. maybe being a thicker walled VC they believe it dissipates heat better than the original design so the ahesive on the windings doesn't fail as much (when over powered)
My point.. Speaker snobs point to Jensen RI's as say they are not the same... but can't tell anyone how SICA changed the design or why...
Have you ever seen any original Chicago Jensen prints? (Alnico or Ceramic) I'm mean originals ... not an internet slappy posting up unverified specs.. but the actual prints with the licencing, patent no# (if any) with the design changes to the current/final print(s) ?? I haven't.. I looked far an wide multiple times on the internet (using a few metasearch engins).
I had to look at the re-coning kits of the Jensen RI and the two vintage C12Ns model .. then examined what is different.
Did Vintage Jensen C12Ns really use 40oz magenets as Webers? My vintage Jensen are not 40z magenets..... So where's the claim of authencity coming from with some that Weber makes a more authentic speaker.. Did Weber copy one design ala.... say the #8220.. Ok... but he still used a 40 oz magenet (which effects the speakers tonality just as much a voice coil change)
Webers make a great speaker.. Not saying they don't ... but its all subjective..
