Testing the JBL Partybox 120 bass performance in a hallway.

We cranked the volume and ran a 40Hz frequency test to see how this speaker handles deep lows. Watch the light display react and hear how the audio fills the space.

Let me know if you want to see a comparison with other portable speakers.
