Well.. it`s actually me borrowing BMS 4590 from superlian to test in JBL 2360`s
Super thnx to superlian for being so kind!
They were working perfect before shipping through Norwegian hard handling viking mail....
Packaging was well done!
One of the drivers do not measure well on the mid.
So actual question is what could have happened and how to fix..
Looking now it should be opened from the back where the speaker terminals is positioned.
Maybe just unscrew and tighten again and hope its just coil "rubbing"..?
Any suggestions is welcome!

When mounting back the diaphragm I hit carefully with the back of screwdriver to have well positioned and at the same time tightening the screws in cross order (same as when changing wheel on car)
Put back the cover.
Measured the driver with REW, measures now well
NB! I used a 55uF (what I found in my shed..) protection cap between amp and BMS so not to destroy it by power on thump from amp!
100uF should also be enough to protect it.
