Pros: Sounds better and more evenly tuned than the JBL Partybox 720. Horn-loaded tweeter gives far more consistent off-axis sound, unlike the Partybox 720’s dual tweeters, which suffer from comb-filtering interference. Gets louder without distorting - the Partybox 720 starts breaking up at high volume well before this does. Projects clearly over long outdoor distances, covering a large area evenly.

Cons: Not quite as deep bass as the JBL Partybox 720. Bass output drops off further at high volume.
