I'm no Sherlock Holmes, or John Holmes for that matter, but those are G12T75's and they have vents.

Yep. I'd be interested in what your take on them is.

Yes but......are they actually better?

Yep!
They sound killer, and very close to the brightest version G12 65, the T3120. But the vented 75s have more of an extended high/low end.
Great speakers!

My take on the G12T75 'evolution': The first version vented 75s ARE similar to a high powered GB, like they advertised. But, the following versions all lost some midrange with each change...the vents, then non vents white label are more scooped(but still have decent mids), then the black/white labels in 87-90 are more scooped yet, followed by the 91-today versions that are more scooped than before.
If you played a vented version and A/Bd it with a brand new one, the difference in the mids would be huge.

I have a '83 JCM800 4x12 cab with G12-65s. I hope I'm not being redundant with these vented G12T-75s. My plan would be to put the 75s in a Bogner 2x12.
I'm also looking at another pair of 75s that are from 1994 taken out of a JCM900 cab.

Yeah, that's been my take on them, too. None of them are my personal preference, but the earlier ones are very different from the latest version. They are good for some things, but I've always found that something else works better, no matter what I'm trying to achieve. I'm still curious what others see in them, though, but don't feel like I'm missing anything.

I don't think so, they're different enough IME. Those Bogner 2x12s are great cabs!

I have never heard Redbacks in person. YT clips comparing RBs with G12T-75s somewhat have a similar sound. The thing is that there are so many versions of the 75s.

FWIW, I don't like Redbacks, but to be fair, I didn't give them a chance to break in. Similar, yes, but I much prefer the T75s, any version. I find the T75s highs to be smoother than the RBs, but that's a broad generalization.

I couldn't tell if it had vents because MikeOx Huge had Oliver Klothesoff in the way.

FWIW, here's '84 vented T75 vs '86 non-vented T75 vs. '13 T75.

What is vented and what does it do or improve
ChurchHill

It's there to provide ventilation for the voice coil, keeping it cooler so it can handle more power. While the vent itself doesn't do anything for the sound, it's only on the first version, which does sound different. The video above posted by @GJgo is a great example of how the different versions sound. I'm not sure what about them is different, but I suspect it's changes to the cone itself, the spider, the voice coil, the doping, or a combination of those things.

The earliest non-vented ones are also still really good and have more midrange detail. I have two in a 2x12 and one of them in particular has a lot more midrange and actually sounds "dark" for a 75. It is perfect with the JP2C+ I have.

Yep, I had a really good sounding 800 cab from 86 that wasn't scooped much. Comparing that to a newer one, the modern version is way more scooped.

The vents act like a coffee filter, only allowing the delicious frequencies to pass. That’s why the non vented ones have so much excessive garbage frequency build up
