Tweeter ID in CRS+'s

Hello to all on this great forum.
Newb here with my first question (s).
Just picked up a pair of CRS+ ('89) from SA recently and am loving them so much. I am lucky enough to have optimal placement and outstanding SDA effects as a result. They are Rosewood Vinyl covered in excellent condition. I am a bit of a tinkerer so I thought I might look into any available upgrades to these, or at least a recap to bring them up to par considering age. Hence came the information overload.
Doing my homework, I noticed that these may possibly have upgraded tweeters already. They are the black silk dome type either RDO194-1, or RDO198-1. Neither of which came stock on CRS's I think. I cannot tell which one I have for the lack of any stamped markings on the magnets, and no photo comparisons in my internet searches.
How can I tell which of these two tweeters I have? Is there a obvious difference? Does the stock crossover tell the tale?
I can post photos if requested.
The drivers are MW 6510 (6/3/88), and MW 6511 (No Date).
Crossover BE 1807 A (3/10/88) Appears to be unmodified by photo comparison.
Passive Radiator unknown. Did not pull.
Pin/Blade cable connector.
Thank you so much for your input.

Pictures would be very helpful to identify the tweeters.

If I remember correctly... One spade connector on the 198 is larger than the other. Both are the same size on 194.

Pics of the Left tweeter. Hope these show.
Under the foam seal on the back is just black plastic. Should have lifted that. Trying to do this with one arm in a sling. -
That is odd. All of mine have a sticker on them with id numbers and build date.HT/2Channel: Emotiva MMC-1, Adcom GFA-555II, Polk SDA 3.1's, Teac TN-300 TT, Polk Center and Sub.
Bedroom system: Carver CT-24, Parasound HCA-800II, Monitor 10's
Additional projects: RTA 12c's -
Looks like the positive and negative posts are the same size so they are 194's. Welcome to CP!SDA SRS 2.3TL's
Silk Audio MS-90-BT integrated tube amp
Yaqin MS-20L integrated tube amp
SDA 2B TL's -
Thank you so much. 194's then, ok.
xjghost, are yours identified as 194's? -
Stock crossovers do tell the tale. They are RD0194s. The 198s are only used in CRS+s in the 4.1TL version which takes a modification to the crossovers.

I don't have any 194's All my speakers are with the original drivers to my knowledge.
This is the back of my RTA 12's tweeter:

I guess the 194's had to have been drop in replacements for some bad sl2000's. Was really hoping when I took a peek at the crossovers they were going to have nice big AudioCaps, Mills, and a fancy new inductor already installed. Wishful thinking. Guess I will do that in time. Not bad for $35 though huh?
Thank you for helping me figure this out. -

I had a suspicion but was not sure. Thank you for confirming.
