foam or felt in the cover

[4343]

I ended up ordering a 12" square by 1/2" thick piece and it arrived the next day. I cut out a piece the same size as the stock foam and put it in. The 1/4" thick felt probably works just as well. The 5" diameter x 1/2" thick foam for a 2445 from JBL Pro is backordered for a month or two.

Now there is a diaphragm that does NOT need any haphazard foam damping!

If only I could afford Aquaplas...
