20 Most Recent JBL Eon15P-1 Main / Stereo Speaker Questions & Answers

Sounds like it could either be the crossover circuit or a distorted speaker cone. The cone is the easy one to check. You need to check that it moves freely at all points. It sounds like you have partly done this, but you just need to make certain you went all the way around the cone checking for free movement.
However I don't think it is the cone, because of the slow way it acts up. That could be the crossover circuit. If you have a look at it and see either an IC or transistor looking parts, then I would have thought it would be one of them acting up - presumably getting hot!
If you can have the speaker outputting sound, with access to the crossover, you could spray these parts (one at a time if there is more that one) with Servisol Freezer spray. You simply wait till the fault develop then spray the suspect part. If it returns to normal you have located the faulty part. If nothing happens, wait till the coolant wears off then try the next suspect.
Places like Maplin stock the Freezer spray.

What is the make and model of the speaker? To trouble shoot this, you need to be able to take the unit apart. There is a circuit board inside called a crossover network, it might be bad OR the tweeter might be bad. To tell you should have a OHM meter for basic testing.

Assuming Bluetooth mode. Insure Bluetooth is enabled on the iPad and the JBL and that they are in the pairing mode.

Sometimes I find it necessary to restart a device to get its Bluetooth pairing mode to connect to the device I am trying to connect it to, such as a speaker or even my car.

Try doing default factory settings.
Step 1. Press the "Power" button located on the top center part of your JBL Charge 4 Bluetooth speaker. The speaker will be powered on when the LED backlight under the Power button is lit.
Step 2. Hold down the "Bluetooth" and "Volume Up" buttons at the same time for roughly three seconds. The Volume Up button looks like a plus sign. Additionally, it's important to hold down the "Bluetooth" button in the center of the device next to the Power button, as it's easier to hold down. After three seconds, the LED ring around the Power and Bluetooth buttons will briefly light up before the JBL Charge 4 powers down.
Step 3. Press the "Power" button again to turn the JBL Charge 4 Bluetooth speaker back on. The Charge 4 will instantly turn on in Discovery mode, with the Bluetooth LED blinking on and off, and the speaker making a pinging sound. This confirms that you've successfully reset your JBL Charge 4 to its default factory settings. You'll need to pair or re-pair any devices you want to play audio through the JBL Charge 4 speakers with the device.

That is a bluetooth speaker sir. Standard device. ANY device with bluetooth should be able to use the speaker with no drivers other than the ones included on the playing device

For the JBL Awake
I just had the same issue and i found a way to solve this :
1. Unplug the power supply
2. Plug it back while holding the [ON/OFF] button
3. The screen shows “UP9” again
4. Do the update with the JBL Music app (I did it with my old iPhone 4s plugged on the 30pin connector)
5. Finish the firmware update ... until the app tells you to unplug the power before restarting the device
(Sorry for my bad English, i’m French)
