Can the JBL Partybox 330 handle deep sub-bass? Watch this frequency test to find out.

I am pushing the speaker from 100 Hz all the way down to 5 Hz to see how it handles low-end performance. This test is perfect for anyone curious about the real-world subwoofer capabilities of this unit.

Drop a comment if you want to see this tested against another speaker.
