Blown driver

First I would like to thank everyone here for the responses on previous questions I have posted. You have given me the education and confidence to finally jumped into my SDA 1's that I bought two years ago. I installed my Speakon connectors and built my interconnect cable and have the speakers connected to my HK Citation receiver, finally!
One of the base drivers sounded "funky". I pulled it and it has a scraping sound upon pushing the cone in and out. Am I to assume that it is blown? If so are all the base drivers similar? I checked the "handbook" and all the drivers are listed as 6 1/2 inch tri laminate polymer bass midrange drives of 4 ohms. It has a number in the face-SR 142117 and no other identifying info. EBay has several listed as MW 6501, are these the same drivers?

Bass, not base.
There should be a paper label on the back of the driver with the model number. Anyway, if yours are the SDA 1 or SDA 1A then all the drivers are MW6501's.Political Correctness'.........defined

Thank you. There is a gray disc on the back, but no model number. They are SDA 1's dated Sept., 1982.

So, none of the mid-drivers have a label on them? That's highly unusual.Political Correctness'.........defined

I checked all the drivers. They have a gray paper disc on the backs with some markings but no model number or anything useful, checking eBay for something compatible.

Can you post a picture of the back of one?Political Correctness'.........defined

The drivers are naked on the backs and the paper discs which I assume are from the drivers were on the bottom of the cabinet -
Now that I am looking at the photos close up, I can see MW6600X. Need to put on the reading glasses!

Happens to the best of us.
That driver is no longer available from Polk. You'll have to check eBay for a replacement.

Picked one up off eBay, just waiting for it to be delivered. After a little listening, I will have to figure my next upgrade.
