How important--matched tweeters on Snell JII

I was wondering: How important is it that the Vifa tweeters that one would put in a Snell JII be matched? I know the crossovers are matched, and this is supposed to be important. But does the same go for tweeters?

Thank in advance,

Of course you have to match the tweets -- to a reasonable degree at least. Just ask the vendor to do it -- it;s not rocket science:)
What does Snell do to match its tweeters (I take it's not something that just anyone can do)?


You just test them (T/S). Tweets are often quite similar.
