RFP Posted December 5, 2011 Share Posted December 5, 2011 I just noticed that one of the spring-loaded terminals gave up sometime in the recent past... the red plastic 'blew out' leaving red plastic chips and a spring in the speaker cabinet... one of the wires was left just dangling! Well, dang! I pulled out the tweeter hoping that I could make a quick repair... well, apparently not. I tried to 'unscrew' the broken terminal, hoping that I would be left with a threaded stud onto which I could simply put a washer and nut and reinstall my loose lead with a terminal on the end. Nope, the broken terminal 'unscrewed' all right, but only to the point where everything is turning. Obviously, I will have to open the tweeter up to fix this... but how do I do that? I see that there are four allen-head screws that appear to be holding the 'baby cheeks' on, but other than those, I see no other fasteners. I'm sure hoping somebody can help me with this...

ZAKO Posted December 5, 2011 Share Posted December 5, 2011 THERE IS A BOLT BEHIND THE BACK LABEL,,,REMOVE LABLE,,SPRING FASTENER CAN BE REPLACED BY A NEW JBL FASTNER...BUT I ADVISE A JBL REPAIR AGENT DO THIS,,SO THAT YOU DO NOT DESTROY THE DELICATE DIAPHRAM,, Quote Link to comment Share on other sites More sharing options...
sootshe Posted December 5, 2011 Share Posted December 5, 2011 Yes, you'll have to prise the JBL label on the back off. They are usually just glued on & if you carefully prise it off you will be able to re attach it. When this is removed you will see the bolt ......undo this.......& you'll be able to get inside to see what has to be done.....be very, very, very careful of the diaphragm!

RFP Posted December 6, 2011 Author Share Posted December 6, 2011 OK, I popped off the back "label" and removed the screw... nothing budged! I think I'll see if I can find a JBL repair guy in the Fort Worth area; I sure don't want to mess this booger up... Rob Quote Link to comment Share on other sites More sharing options...
djk Posted December 6, 2011 Share Posted December 6, 2011 You have to remove the front horn first, then the bullet, then the diaphragm. You may have to hit the horn with a rubber mallet. Quote Link to comment Share on other sites More sharing options...
