Hello,
I bought a new pair of JBL D16R2441 diaphragms.
I had them installed by a technician today, but some questions remained...
The D16R2441 diaphragms mounting surface looks different to the original D16R2450 diaphragm!

The D16R2441 has 8 spacers on its back.
The original 2450 doesn´t have these at all.
I´ve allways read in this forum the 2441 diaphragm is a plug&play easy swap into the 2446 driver...
What has to be done to the 2441 to make it fit ?
My second questions is about centering the diaphragm in the magnet gap.
The 2441 diaphragms had a notepad included saying that these are not self centering!
Putting these diaphragms into the 2446 drivers, there actually wasn´t much space to move anyway. We tightened the srews and put a 20hz sinewave on it and simply checked if it runs free without any rubbing.
Is that allright or do they have to be aligned in a different way?
