please help an audiophile's widow

@dill not sure if the -030 at the end makes a diff.

See if the Paradigm speaker model (not the tweeter, but the whole speaker model) is listed @ the bottom of the following (linked) page.

If it is then the tweeter listed should be a suitable replacement mounted to the existing tweeters faceplate.

@erik_squires Looks like the 3 trailing numbers are for the same tweeter/driver, but different waveguides for different model speakers. 

Firstly I am sorry for your loss not only of your spouse, also for the music that brings you comfort.

maybe reach out directly to paradigm directly for guidance. In my experience with them back in the day they were very responsive.

sorry for your loss of your husband and the speaker. Do you have a picture you can post? That would be a big help.
