Thanks for your answer ,but the question was the fiberglas showing in the JBL 300 manual for the bottom is missing ?
Is this correct ????

I would say it was missing. If you do put it back in don't cover the crossover. Use the posted picture as your guide.

I have owned 4 sets of L-300's and FWIW none of the sets has had the fiberglass in the bottom. Not sure why? Even so I never felt the need to add it.
