400 Watts of Party on Wheels
The JBL PartyBox 520 is built for big crowds. Two 7.5-inch woofers and two 1-inch dome tweeters produce 400W RMS of JBL Pro Sound with a 40Hzā20kHz range, while AI Sound Boost adapts to the track in real time to keep the output loud and clean even at peak volume.
A futuristic light show with strobe effects moves with the music, and mic and guitar inputs turn it into a live-performance rig. Control playback, EQ and lighting from the JBL PartyBox app, and scale up by linking multiple JBL speakers over Auracast. A USB-C port can also charge your devices.
The replaceable 99Wh battery provides up to 15 hours of playtime, with a 10-minute charge adding around two more hours. Sturdy wheels, a telescopic handle and an IPX4 splash-proof rating make it easy to roll out to the garden, beach or pool deck.
