There is some glue on the back of the tweeters that may make coaxial mounting difficult. You could probably get the glue off with a heat gun though. Great sounding set for the cheapness!
lowered price to 90 shipped!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!?
only minor cosmetic issues. A little ca glue on one of the grills and really not an issue, but some hot glue on the back of the tweeters from my last install. Less than half of ebay price!
