So just like the JBL PartyBox 330, the JBL PartyBox 130 is here much sooner than I expected. And just like the JBL PartyBox 330, there are some important upgrades on the JBL PartyBox 130… but there are some changes on the JBL PartyBox 130 that I don’t like. But regardless, the JBL Partybox 130 is still one of the best Mid sized box speakers that you can get and you can’t go wrong with this speaker. So lets see what the JBL Partybox 130 is all about and lets see if its worth upgrading if you already have the JBL Partybox 120 or the JBL Partybox 110.
