How to Fix JBL Bluetooth Speakers with Distorted & Crackling Sound at home without expensive tools. The repair techniques learned here can be used for the JBL Charge, Flip, or other speakers from JBL, Sony, Blaupunkt, and any other Bluetooth speaker that is producing distorted, crackling, or weird sounds. In this easy DIY repair guide, I troubleshoot how to identify the cause of a broken speaker that is making distorted and crackling noises. I will show you how to check for air leaks, debris, and loose screws before moving on to a full new woofer replacement. I will open up the speaker housing, test the driver in free air, and explain exactly why overdriving your speaker causes that annoying crackle from broken voice coil. These steps work for almost any portable Bluetooth speaker and can save you hundreds of dollars by repairing your speaker instead of buying a new one.

![Harman Kardon Onyx Studio 9 speaker sound/bass excursion test [no grill]](https://i.ytimg.com/vi/mbuTh_yBIlI/mqdefault.jpg "Harman Kardon Onyx Studio 9 speaker sound/bass excursion test [no grill]
How to remove the speaker grill on the Harman Kardon Onyx Studio 9 portable bluetooth speaker + bass excursion and sound test to see how loud and powerful this portable Bluetooth speaker really is testing dB SPL test. The Onyx Studio 9 is known for its premium design and rich sound, but today we focus on what’s happening behind the grill. I demonstrate how the grill is held in place using plastic clips (similar to Hi-Fi speaker fabric covers) and explain how to remove it carefully without damaging the housing. Once the grill is off, we take a closer look at the woofer, passive radiator, and three tweeters, then move on to a real sound & bass excursion test to check speaker movement, low-frequency performance, and overall loudness. Note: Removing the grill may cause minor scratches if done carelessly. I recommend using tape or plastic tools to protect the speaker finish.
