Dominate the Night with 1100W JBL Pro Sound
The JBL PartyBox Ultimate isn’t just loud—it’s earth-shaking. With 1100 W RMS power driving dual 9-inch subwoofers, dual 4.5-inch midranges, and dual 2.75-inch tweeters, it fills huge spaces (think basketball courts) with rich bass, crisp mids, and punchy highs. Dolby Atmos over Wi-Fi adds immersive depth so you feel sound from all around.
Blazing Lightshow, Splash-Proof Build & Smart Controls
Built tough with IPX4 splash resistance, the Ultimate features dazzling RGB lighting—from starry effects to strobes to floor-projections—that sync to the beat. The built-in PartyPad gives you DJ-style effects at your fingertips; app control via JBL One lets you tweak EQ, lights, and source. Despite its heft, it moves with you thanks to sturdy wheels, a carry handle, and clever cable management.
