MONITOR and SDA series woofers

Polk made a lot of 6.5 in. woofers for their monitor series and SDA series speakers that all look the same but different model numbers. Does anyone know the differences between these speakers and if any of them are interchangeable?
What are the new replacement woofers from Polk like? Do they look the same? I think I read somewhere that they're not sticky. I'm sure the originals were sticky for a reason.

There were a few 4ohms versions, and several 8ohm versions. The early MW6500 was very efficient, but bottomed out if overly driven. It slowly worked up to the 6503 which handled more power, and resisted bottoming out. As for the sticky part I don't know if the originals came sticky, or got sticky after a couple years.Please. Please contact me a ben62670 @ yahoo.com. Make sure to include who you are, and you are from Polk so I don't delete your email. Also I am now physically unable to work on any projects. If you need help let these guys know. There are many people who will help if you let them know where you are.
Thanks

All the drivers are designed with different specs and therefore are not really interchangeable. The original drivers came sticky and as far as I know the replacements are too.Political Correctness'.........defined

Yep; My SDA 1's were sticky the day I bought them in 1983. I'm surprised they haven't dried up after all these years. Some things are just better sticky.:D -
Why are they sticky?
It's doped paper, which helps the cone keep it's shape.Political Correctness'.........defined

Just a guess, But I think it was used as a damping material. Polk literature says they use a three layer cone construction. It must be one of the layers. And I've seen mentioned somewhere before about a damping material used in the cone. -
I read somewhere that the sticky coating reduces resonance and leads to cleaner midrange.
