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.
