Credo tweeter torque nm setting

hi all, credos in da house at the moment. I have torqued up the drivers from 2.5 nm to the magic 3.6 nm just wondering if the tweeters need doing. They are a 1997 model and would suggest that have never been touched. Do you think it's needed or just leave be?

Just wanted to get it right while I have the tool at hand.

  Thank you in advance.
