We sell the metal type now. No more plastic. The metal style tends to last longer. Even if you cannot see damage, there can be an issue causing low output or no output. Sometimes the crossovers may have an issue too.
Hi, I have a set of JBL Jrx 115 , this past weekend my tweeter was making noise and at the end of the night the tweeter went completely out, Do you think I just need to replace the Diaphragm?
Great video, helped me a lot. I have a question. Besides replacing the diaphragms, I also had to replace the audio resistors from the crossovers because they were burnt. The resistors are 10-watt, 16-ohm; i already soldered new ones and the twitters sound like new. But just to make sure, what can cause a resistor to burn? Thanks!
Yes, we test all repairs on a signal generator when complete. These particular diaphragms are self-centering, so it is rare to have any rub or scrape issues when complete.
The JBL 2412 diaphragm is just like the video shows it. We have other models which are different. Some use round wire, other use edge-wound. It all depends on the actual design.
HI, i have 2 units of JBL EON1500 and i realized one of the tweeter sound very weak and caused whole speaker lack of hi mid frequency. When i open up the driver, i didn't see the breakage in the diaphagm as shown in your video. May i know: 1) The weaker response is it caused by the spoilt diaphagm or magnet? 2) There is after market diaphagm around, some are in black plastic and some are in metal plate, does this two make a different in quality and sound? Thanks.
