So over the last few years, the JBL Partybox 110 has been my favorite mid sized box speaker to recommend… and I feel that the 110 is more than enough for most people, it sounds good, it get very loud off of its internal battery, it has a ton bass, and it has a really good looking light feature. But now, we have the JBL Partybox Club 120 which more refined and it has some important upgrades over the 110. Nonetheless, today we’re going to see the the Partybox Club 120 is all about and we’re going to see if it worth upgrading if you already have the 110.
