This was probably discussed here before, but can't find anything.
Would like to know what weight mass ring (JBL) was used in which woofer.
I believe that there were different weight rings for various drivers.

I posted a chart years ago.


Googled "JBL Mass Ring", looked in Images and there it was:


Note that the mass ring weight doesn't include the gob of glue required to hold it in place. ;)
