One of mine went bad so I pulled it out but couldn't find any type of brand or model number before looking online for replacements. I randomly found these:

But I really need the sensitivity, frequency range, and power handling specs of the originals in order to know if those replacements will be close enough not to drastically change the sound of the amp models that use the full range speaker type.
Found the main drivers here:

But I can't find the same for the two tweeters.
