After months of patient waiting, I finally found a second Pulsonic T1281 to fill my 2x12 - a '72 'Rola' this time.
It arrived yesterday, after the seller confirmed there was no coil rub and agreed to ship it halfway 'round the world. To be fair to the seller, he didn't claim to be an expert, and he did a bang-up job of the packaging.
Unfortunately, there was some clear coil rub on arrival:
Slightly disheartened, I installed both speakers in the cab and did some playing. The nice thing about the 1936 cab is how easy it is to switch between the individual speakers, so I was pretty quickly able to ascertain that they're both "good", with the standard variation in tone you expect from similar speakers. The '70 is a tad louder, but the '72 (this one) has a softer top end. They complement each other nicely.
Most importantly, I couldn't hear any of the telltale sounds of coil rub. No scratching sounds or painful resonances. I didn't absolutely crank the speakers, but I did eventually run the cab in parallel out of my JTM 45/100 (with a loadbox), so it would have been seeing half the 45/100s power - and it sounded fine (spectacular, even!)
Is this surprising? Should I expect coil rub to rear it's ugly head in future? Are there any further tests I should try?
I did orient the speakers in a way they wouldn't have been previously, with terminals facing the bottom of the cab. I've read that this can resolve coil rub over time, but no idea how effective this really is...
Edit: here's the other, for comparison:
