JBL Partybox Ultimate

$ 1,699.95

Fill your next party with balanced and immersive Dolby Atmos music, live guitar, singing, and a dazzling light show when using the PartyBox Ultimate 1100W Wireless Party Speaker from JBL. Fill large spaces with dual 9" woofers, 4.5" midrange drivers, and 2.75" tweeters that pump out a massive 1100W of sound. Both dual-band Wi-Fi and Bluetooth streaming are supported for playback from mobile playlists, a home network library, or online streaming services. Live music and karaoke are also options with dual mic inputs and a guitar jack. All of this is supported by a multi-colored lightshow with starry LEDs, cool light trails, strobe effects, and ground illumination, all of which pulsate in sync with the beat of the music.

Dolby Atmos Sound
When you pair the PartyBox Ultimate with access to a compatible Hi-Fi music service, you can use the speaker to play Dolby Atmos-compatible tracks. Dolby Atmos delivers 3D spatial effects that add a heightened level of immersion to your music.

Any location you place the PartyBox Ultimate is a good one, thanks to its built-in self-tuning feature. Every time you turn on the speaker, a self-tuning function will run to automatically tune the quality of audio output to match its current surroundings.

Go Even Bigger
If 1100W of power are not enough for you, you can go even bigger by pairing two or more PartyBox Ultimate speakers together.

Surprisingly Mobile
You'd think that with such a large speaker it would difficult to move around, but a built-in handle and wheels makes it easy to place the PartyBox Ultimate exactly where you want it.

Take control of the PartyBox Ultimate with the JBL One mobile app. JBL One lets you customize light colors and patterns, setup multi-speaker pairing, adjust EQ settings, manage playback, and more.

JBL PartyPad
Built into the top panel of the speaker is the JBL PartyPad. Tap, hold, and slide on it with your fingertip to remix tracks with DJ-quality effects.
