Short answer: the Teufel Rockster 2 if sound quality matters most, the JBL Partybox 520 if price and portability matter most. The Rockster 2 ranks #4 of 12 large party speakers at $1,269.94. The Partybox 520 ranks #7 at $879.95, $389.99 cheaper.
The Rockster 2’s driver layout is the real story here. Its single horn-loaded tweeter gives far more consistent off-axis sound than JBL’s dual-tweeter Partybox designs, which suffer from comb-filtering interference between the two drivers, and reviewers found it gets louder without distorting where JBL’s larger Partybox 720 starts breaking up. That single-tweeter horn design also drives its 132dB max volume rating and its 15 inch woofer, both larger than anything in the Partybox 520’s spec sheet.
The Partybox 520 counters with practicality and features. RTINGS found it loud enough for backyard use and unusually well equipped for a battery party speaker, combining very high output and deep, chesty bass with wheels, a telescoping handle, a capable app EQ, lights, USB-C audio, and mic and instrument inputs. Its cons are the ones you’d expect from a JBL Partybox: it is very large and heavy, Bluetooth latency is high for video, its front-facing design loses mids and treble to people off to the sides, and the bass-heavy default can make dialogue less clear without EQ.
Everything else worth noting: the Rockster 2 weighs 96.5 lbs (43.8 kg) against the Partybox 520’s 56.2 lbs (25.5 kg), nearly double, and adds XLR inputs plus a Teufel Party Link mode supporting up to 100 speakers, versus JBL’s Auracast on the 520.
Buy the Teufel Rockster 2 if you want the most consistent off-axis sound and the highest rated max volume, and can handle its weight and price.
Buy the JBL Partybox 520 if portability, wheels, and a lower price matter more to you than the Rockster’s off-axis consistency advantage.

The Two Speakers In Full
Teufel Rockster 2: $1,269.94 eBay
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.

JBL Partybox 520: $879.95 Amazon B&H Photo Video eBay
Pros: JBL’s biggest battery-powered PartyBox after the 720 combines very high output, deep chesty bass, wheels and a telescoping handle with a capable app EQ, lights, USB-C audio and mic/instrument inputs. RTINGS finds it loud enough for backyards and unusually well-equipped for a battery party speaker.
Cons: It is very large and heavy, Bluetooth latency is high for video, and its front-facing design loses much of the mids and treble to people off to the sides. The bass-heavy default can also make dialogue less clear without EQ.
