Description

Unmatched legendary JBL sound
With 1500 watts of legendary JBL sound, the PartyBox Ultimate 2 delivers power you can hear and feel from the very first beat. That's enough sound to rock a space the size of four basketball courts. Horn-loaded dual professional-grade PEN tweeters drive bright, detailed highs, dual 5” mids keep vocals strong and present, and dual 10" woofers with bass ports bring deep, physical low end. AI Sound Boost works in real time to keep everything loud, clean, and balanced, even when the volume is to the max. It’s sound built to scale with the moment, no matter how big it gets.

Bold lightshow experience
The PartyBox Ultimate 2 features a revamped lightshow built around ripple-wave effects that sweep across the full front panel. Multi-layer lighting adds depth and motion, while a bold floor projection pushes the visuals out into the room. Together, the lights move with the music, filling the space and keeping the energy high.

Intuitive touch-screen control top panel
The touch-screen control top panel makes it easy to take charge of the night. At the center is a volume knob that doubles as a touch-screen controller, giving you quick access to sound, lighting, music, and more. The controls respond instantly as the vibe shifts. Play built-in party games—because no party is complete without games. Everything is right where it should be, so you spend less time thinking about settings and more time in the moment
The loudest, fiercest JBL PartyBox ever, the Ultimate 2 is built to bring festival-level energy anywhere it’s set up. Legendary JBL sound fills massive indoor and outdoor spaces—up to four basketball courts—so everyone feels the music, from the front row to the edge of the crowd. The sound hits big and physical, with vocals that stay front and center and bass you feel in your chest. AI Sound Boost works in real time to keep everything sounding huge, even when the volume is turned all the way up.
The lightshow is just as epic. A full-panel display sends ripple waves across the speaker, while layered lighting and bold floor projection extends the effects even further, creating a deeper, more immersive experience. Together, sound and light create a live-show moment that pulls everyone into the energy.
An intuitive touch-screen control top panel makes it easy to take charge of the party, while karaoke and DJ features create endless ways to practice and play—from EasySing AI vocal removal and an optical input for easy TV-based karaoke setups to a pro-level XLR line-in for a direct DJ-console hookup. Built-in Wi-Fi, Smart EQ Mode, and JBL Auracast™ support keep the music flowing when the crowd gets bigger. Finished with splash-proof durability and rugged wheels built to roll anywhere the night leads, the Ultimate 2 is made for people who go all in. This is the JBL PartyBox built for the biggest nights.
