#6 JBL Partybox 300: $300

  • Negatives: Hard to carry, too tall, drags on the ground. Max spl and bass extension are only as good as the Partybox 100. No real reason to ever get one, get a Partybox 100 instead. Note, JBL daisychain is not compatible with any other non-JBL speaker and is possibly a fully digital signal.
