I am holding a brochure that refers to BOTH the 6 1/2" mid-bass drivers AND the tweeters as "tri-laminate". I used to think it was just the tweeters. Then, recently, I thought it was just the mid-bass drivers. I need to sort my....Bitfrost.Yes it is a tri-laminate tweeter. That is why some are gold, silver or a dark color. I'm guessing it was which vapor deposited coating when on last.

It's the tweeters, not the mid-drivers.

I thought "TL" stood for "tri-laminate" which was the certain combination of polymers on the cone, or something to that effect. Maybe the last non-TL 1.2 had the tri-laminate drivers but didn't have the same array as the TL, which might explain the different crossovers.
Yes it is a tri-laminate tweeter. That is why some are gold, silver or a dark color. I'm guessing it was which vapor deposited coating when on last.
It was explained to me the reason for the different colors was they could not control the outcome of the process. Since there are only two metals deposited, the polymer being the 3rd layer, I'm pretty sure the 3 different colors were not the result of which coating was applied last. -
It's the tweeters, not the mid-drivers.
The brochure reads: "Each SRS model features an array of Polk's exclusive Trilaminate Polymer 6 1/2" midbass drivers that exemplify today's state-of-the-art loudspeaker technology."
A few pages later it says: "The Polk SL 3000 Trilaminate Dome Tweeter sets new standards for bandwidth, flatness or response, phase linearity and power handling."

Not the same. The speakers in the eBay ad are 1.2's. The speakers in the Audiogon ad are 1.2TL's.
I goofed. I went from the original 1.2's ebay listing to an ebay link of the audiogon 1.2TL's for ~$4500 and mixed them up.

Marketing screw up. It's only the tweeters. -

That would explain why the drivers for the last non-TL 1.2's and the TL's are exactly the same. -

Maybe a smokers pair. A reduction to 500 or lower maybe. 3 torn drivers, ouch.
Then a trip to Johann's crafts for grill cloth material and a bottle of 409 cleaner from the grocery store.
409 dissolves nicotine almost instantly. I've used it many times on speakers and receivers. Get the scented 409, it makes the messy clean-up smell a bit easier to bare.Most people just listen to music and watch movies. I EXPERIENCE them.
