Noticed the white seals that go on the square base of my 2405 tweeters are missing, might still be at the JBL pro shop but if thet arn't I have the Parts Express 3/8 foam "weatherstripping" that I was planning on useing on all my components going into my L200b speakers. Will the Parts Express "weather stripping" be a good substitute for the 2405 white seals? I'm guessing the seals are used to make a air tight seal between the 2405 tweeter and the baffle board. The 3 1/8" cutouts for the 2405 tweeters is a perfect fit. The cut is very clean and in fact smoother then the factory cuts for the LE85 and 136A.
