Hi Team
I replaced some diaphragms in a pair of 2402 bullet speakers. Got them from a well known speaker supplier in mid-West. They were not cheap and they did not seem AliExpress quality.....

When I tried them out I found the volume level was next to zero. I had to put my ear to the speaker to hear that it was playing and it seemed clear, just very low. On contacting the supplier they suggested the diaphragm needed adjustment by loosening the bullet and moving all the parts around whilst connected to the system and playing.

Anyone know the full correct way to adjust for max volume ?

Thanks in advance
