Have 2 jbl 615 get good base and sub but neither tweeter playing

Hello Dane, if the fuse is good, you can have the speaker and driver of the horn, open, therefore it will not sound

Hola Dane, si el fusible esta bien, puedes tener el parlante y el driver de la bocina, abiertos, por lo tanto no va a sonar

riverray1969 it would help if I knew the exact model number of that JBL sub you are referring to. With that info I can provide exact specs.


Basically, you need to build/modify an sub enclosure that is suited for the sub, the music you mainly play, and vehicle tuning. Generally, sealed enclosures will provide tighter bass response and get decently loud. Some would argue that it will give you greater sound quality. A ported enclosure will give you a louder more booming sound. That depends also on where the port is tuned (ex. 32 hz, 36 hz, etc ). You need to make sure that the enclosure meets the sub's airspace requirement as well. A customized well made enclosure is just as important as the sub you put in it.

The crossover caps may have failed, or the tweeters themselves burned out. Using a small 1.5 volt cell touched across the tweeter leads should produce a sound. If not- they are burned out.

Which cord are you thinking of? If you look at the subwoofer there are 4 cords. One to the left tweeter, one to the right tweeter, one to the computer and one to the power.

1. As both the tweeters are woring then those 2 cords are OK.
   
2. As both tweeters are working then the cord to the computer is OK.
   
3. As both tweeters are working then the cord to the power is OK.
   
4. Therefore it is not 'just the cord.'
   

What I would suggest is checking that the sub has not been turned down - one of the silver posts on the sub. If that is not the case and you cannot turn the sub volume up then I suggest that you replace the system. They probably cost more to repair than to buy new.

Swap the speaker with the other one to prove the source is NOT the problem and then get the tweeter fixed.

open it up and check cables leading to sub (large speaker) they're notorious for falling off - getting banged around

yes you can

Sound like the tweeter is blown, take to local jbl agent for service.

If no warranty - remove amp and check sub to another amp to isolate speaker from internal amp. Either the amp blew a channel or subwoofer blew. JBL's are typically well built. Has this speaker often been pushed loud often?
