Tweeter Speaker Repair
Customer sent to me this set of speaker with the complaint of intermittent no sound from the tweeter speaker. In the above photo, the arrow pointed to the tweeter speaker that was having problem. Below photo is the tweeter speaker that I had removed:
It is easy to check if the tweeter speaker is working or not. Simply use your Ohmmeter and measure the two points of the speaker connector.
A good one will show Ohm’s reading and a bad one will have no reading and an intermittent one will occasionally show some readings. The one that I had checked had intermittent reading and it needs replacement.
I got a new replacement for this tweeter speaker and when everything was fixed I checked the Ohms reading and it shows 7.1 Ohm which means it was good. If the Ohms is too high say 500 Kilo ohm also indicate problem with the speaker coil.
The more you test on the tweeter speakers the more you will know about the Ohms value. See the photos below:
Finally the tweeter speaker was fixed back to its original location and the sound was so good.
Conclusion- Troubleshooting tweeter speaker is pretty straight forward. Just by checking on the coil resistance you will have a rough idea if it is good or bad. Of course you need to check on other parts too like the cone paper if it tear or not and etc.
