Welcome to the forum. I don't own any axiom subs but another member here , exlabdriver has a pair of 800's and absolutely loves them. Cant stop him from raving about the. Now I am not sure if all 800's are sealed so hopefully he will chime in and share his experience with you. Many others have the 800's and I have never heard a disparaging word about them .

DOG is GOD spelled backwards.
What others think of me is none of my business.
