More power. More detail. More ways to own the party
Stamford, CT, 4, October 2026 – When the music matters, go Ultimate. Introducing JBL PartyBox Ultimate 2, the most powerful and advanced PartyBox ever created. Built with everything JBL knows about powerful sound, deep bass, creating unforgettable party experiences.
The latest PartyBox delivers ultimate JBL Legendary Sound with stunning clarity, immersive lighting and next-level features designed to keep every crowd moving. From packed celebrations to backyard parties, PartyBox Ultimate 2 fills every corner with sound you can feel and detail you can hear – whether you’re indoors or outdoors.
“As a global market leader in the party speaker category, JBL continues to drive the category forward. Pulling on all our experience in professional and portable audio, PartyBox Ultimate 2 is a true flagship of our PartyBox range as it represents the very best of JBL”, said Carsten Olesen, President, Consumer Audio at HARMAN.
Huge sound with every small detail
PartyBox Ultimate 2 delivers an astonishing 1500 watts of Legendary JBL Sound, over 36% more than the previous generation*,but power is only part of the story.
A completely upgraded acoustic architecture combines dual pro-grade PEN tweeters with horns – the same as those found in JBL’s Professional systems – dual 5-inch mid-range drivers and dual 10-inch woofers. The result is a wider soundstage with deeper bass, richer vocals, and greater detail across every frequency. Sound that hits harder, reaches further, and reveals more of the music you love.
AI Sound Boost continuously analyses audio in real time, optimizing performance for powerful, dynamic sound with very low distortion, even when the volume is pushed to the limit.
Shine a light on the performance
Sound this big deserves a powerful visual experience. PartyBox Ultimate 2 features JBL's next-generation PartyBox lightshow, blending dynamic ripple effects, layered lighting that creates depth and movement, and bold floor projections that transform any space. From the first beat, synchronized lights pulse with the music, turning every gathering into an immersive party experience.
Built to run the party
Control the action, even when the party is humming. The new volume dial doubles up as a touchscreen controller, providing instant access to music, lighting and key settings. As the first PartyBox to feature an integrated touchscreen, PartyBox Ultimate 2 even lets you check what song is playing and which lightshow is on – keeping everything at your fingertips without interrupting the party.
Want to take it up a notch? Instantly transform songs into karaoke-ready tracks with built-in EasySing AI Vocal Removal, or turn up the fun with a selection of party games to choose from.
Built to party. Made to move.
Despite its powerful performance, PartyBox Ultimate 2 is designed to move with the party. Larger, sturdier wheels improve transportability, while built-in Wi-Fi, Bluetooth LE Audio and multi-speaker connection Auracast™, AirPlay, Chromecast and Spotify Connect provide greater flexibility for every listening setup.
Whether you’re streaming playlists, connecting professional equipment or synchronizing multiple speakers, PartyBox Ultimate 2 is designed to handle it all.
The JBL PartyBox Ultimate 2 is now available on JBL.com and at Best Buy starting today for $1,799, with availability at additional retailers in 2027.
