Speaker Questions in 2x12 Cabinet:

I wouldn't worry too much about the resonant frequency. Mostly its a useful number to help tune a cabinet but in reality for the most part you are never hitting notes that low with a guitar so it's not really that relevant. Specs on paper won't tell you anything in the end - Only thing that matters is you like what goes into your earholes.

Yeah agreed.
Some people hear less highs with a Creamback 75 over the 65, I heard the opposite in videos. I have yet to hook them up and see. That's why I ditched the big gold S303s. Seems like a speaker one would want to keep on hand, but just too harsh to my ears.
Go with what you hear. Sadly trial and error.

Everything that goes into my ear holes gets mangled.

I know!!! I hate the swapping out!!!

The biggest difference I see between these speakers (aside from weight) is the Resonance Frequency.

The 100watt Jensen has a RF or 70

The 80watt Jensen has a RF of 72

The Celestion 70/80 has an RF of 85

Not sure what that means...

Voice coils are Aluminum on the Italian made 100watt Jensen and Copper on the Celestion and the 80watt Jensen...

The resonant frequency is the peak of response in open air, no cabinet.
 
I'm leaning towards either installing both Celestion 70/80's or perhaps pairing a 70/80 and the 80 watt Jensen.

Any 4x12 speaker cab. No ports. I have 2 - 2x12s closed with no ports. It isn't a bass or kick drum cab, I don't overly see the big advantage for guitar. Closed back adds some thump and more directionality.

True! None of my cabinets have porting either now that i think about it. Completely sealed except for the speaker front itself. Plenty of thump and push
 
I borrowed some speakers today and I tried the Celestion Vintage 30, the G12&75 Creamback, WGS ET65, WGS Veteran 30, and Celestion G12H30 Greenback. I tried these up against my 80 watt and 100 watt Jensen Neodymium's and my pair of Celestion 70/80's. I demo'd them thought a DSL40C that I have here on the bench awaiting conversion to a head cabinet via a Mission Engineering cabinet. All EQ's were set to Noon.

I asked a chum to listen to the speakers without knowing which ones where being demo'd for reference. The pair of Celestion 70/80's sounded better than any of the other speakers to both of us. However, the 70/80's didn't sound good paired with other speakers. But when paired together, they sounded far more articulate than the others.

the Greenback, Vintage 30 and the Creamback both a had a kind of 'scooped' effect which my ears perceived as a lack of clarity. Each one sounded like it had a "duller" tone

The Jensen's were good but I felt the upper mid and high end were too bright and somewhat "brash" to my ears (my chum is a producer and agreed)

The WGS speakers sounded good, but each one seemed to have a sort of 'peakiness' in the tonal spectrum, like each one had a separate emphasis on a certain frequency.

The 70/80's were by far the most neutral of all the speakers we tested. It was as if they added no color or character to the tone, they just delivered whatever the amp was producing. No scooped tone, very good mids and controllable high end without being brash.

Basically free too, since they were on the shelf here... LOL

See I wouldn't have thought but ears do not lie! It's gotts sound good to end user.
Quite a job you had there.

Funny thing...I like my speakers to deliver clarity at stage volumes. Many folks seem to like to hear the speakers "break up," because this phrase appears over and over again online, as does the "midrange spike" in the Vintage 30's...but "break up" is distortion and a general lack of clarity.

I also discovered that I don't like a speaker that "colors" or adds elements to the sound. I want the speaker to just amplify/project without any bias.

The 70/80 seems to handle the high gain settings with greater clarity, and it's kinda what it was designed to do???

I should have used them a long time ago before spending $325.00 on a pair of "better" Jensen Neodymiums and $160.00 on a custom 50watt, WGS Reaper 55Hz...LOL
