JBL CS100 tweeter replacement part

[dannyjmf]

Just hands on purchased a pair of JBL CS100 for my computer mains channel use and discovered one of the tweeter seems had sound bad ... Any equilavent replacement parts for the CS100 tweeter? thanks

Can you access the tweeter and photograph it - front and rear if possible?

Give measurements of tweeter faceplate and mounting hole in cabinet, if possible.

Also, check that it is really the tweeter that is at fault by swapping it with the 'good' tweeter from the other cabinet.

Since this was purchased used ... Apparently it seems someone has opened it before and did some wierd wiring alterations for some unknown reason ... The measurements as shown below but i assume it is a copy of audax tweeters perhaps 😅

Unexplainable 😅😅😅 this time round even wierd with 2 fullrange / midrange with different part number 😅 i wonder what actually is going here ... Different part number

It seems these speakers simply are what they are! 🙂

A search for a JBL TWC AH120DM tweeter comes up blank - have you tested the 'faulty' tweeter yet?

I wouldn't agonise over the choice of tweeter in this scenario, but similar types are certainly available:

since the speaker was bought used ... from used electronics store ... from the electrical tape was there i was pretty sure it was tempered ... now i put everything back together it sounded ok now ... it seems like caused by a loose wire that connects to the tweeter ... Btw i am sooner going to buy the center channel soon as my plan is to get their 4' full range drivers and make new ported enclosures (or even passive radiator alignment) for them as the original boxes were sealed and sounding "bass less" (the bass control maxed out still bass less) ... but the vocal and trebles definitely a plus point ... as my old bookshelfs suffered from lack of vocal

I'm glad you've solved the "bad" tweeter problem.

For completeness, I attach a photo of your speakers along with the matching centre speaker.

 

[dannyjmf]

wow center channel ... is the set of speakers in the photo shown yours?

 

[Galu]

No, search for JBL CS100 images.

it seems like the driver is suitable for ported configuration also ... might need to try out and see ...
