JBL BOOMBOX - EXTREME BASS!!! Low Frequency Mode [2017]

*LISTEN WITH EARPHONES* or else all you will hear is clipping and vibration noise. This video shows the exact difference on the Low Frequency Mode! I took about 10 minutes to open the JBL BOOMBOX half through. Tear down of JBL boombox will take time friends. *SUBSCRIBE TO STAY TUNED* If you’ve a JBL BOOMBOX I won’t recommend playing songs in low frequency mode above 60% volume, passive radiators goes out of control! That’s one heck of a problem here! I will be uploading videos on jbl boombox without grill soon! Stay tuned!
