Hello,
10 years on a speaker is fine. You can check for dry rot but I doubt you will se any. I think it will come down to looks. With the tweeter/ midrange array on the Tekton. vs the coincidence setup you will be happy either way. The one thing is the Tekton speakers will be new. Plus with the upgraded parts it will be amazing. I think it is between these two brands. I have only heard the double impacts at a reviewers house. They were really great on the Classe preamp and mono blocks.
