Monitor 10 tweeter replacement or thermal switch?

Hey guys! First post here.

I recently acquired a set of Monitor 10s and from pics I posted on FB and rear labels, I’m told they’re 10B’s.

When I first hooked them up, at higher volume I noticed crackling coming from one of the tweeters. From researching this (esp in this forum) I quickly learned that the RD-0194 replacements were available from Polk and a decent easy upgrade as well.

Polk has them in stock and I’m ready to order, however this morning on my FB post someone suggested it might not be the tweeter at all and is possibly a thermal switch that has gone bad, which I should replace with a resistor. So...

1) I figure I’ll replace the tweeters anyway, but how do I know if the thermal switches need replaced, and
2) is that an easy enough/cheap enough job to do on my own?

I figured the tweeters would be easy enough to do but I’ve never worked on speakers before and these are my first true vintage speakers (these replaced my early 90s Polk S10 floor speakers).

Thanks for any and all help guys! Glad I found this resource.
