Differences between Celestion 12 T 75 and V 30 ?

[PenttiL[_2_]]

Where I can find some information about these two types of guitar
elements ( Celestion 12 T 75 and Vintage 30 ). As like frequency
responses, sensivity and so on. I'd like to compare them. If I can hear
right, there's an odd resonance-peak on upper-middle at 12 T 75. Is this so?

Perhaps by Googling "Celestion Speakers"?

But, to save you some time:

I don't know what you might consider an "odd resonance peak", but at any
rate the speaker cabinet may be more of a factor than the free-air
performance of either speaker.

I remember visiting a music store that had a plexiglass "wall of
speakers", where they had mounted one of every guitar driver they
carried. While that wouldn't be the ideal situation to audition
various speaker models (they'll sound yet different when installed in
a cabinet), you could still get a feel for the distinguishing
characteristics between them.

The driver makes no sense without a cabinet.

I have a deconvolution of a Marshall 1936 cab I can email to you.
The 1936 uses two G12T75-8 speakers.

It does involve a guitar amp, microphone of uncertain parentage* and a
lousy room. It's a 35 KB wav file. You can run white noise through it
with a convolver (like SIR) , then capture the output.

*I think I used the Behringer ECM8000 but am not sure.
