JBL has announced the JBL PartyBox Ultimate 2, calling it the most powerful party speaker it has ever created. According to JBL’s official announcement, the new JBL PartyBox Ultimate 2 delivers 1,500 watts of JBL Legendary Sound, more than 36% greater output than the previous generation, combining professional-grade acoustic components, AI Sound Boost technology, a built-in touchscreen controller and synchronized party lighting into a single portable speaker system.
“As 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 from the JBL PartyBox Ultimate 2
The JBL PartyBox Ultimate 2’s completely upgraded acoustic architecture combines dual pro-grade PEN tweeters with horns, the same technology found in JBL’s professional systems, alongside 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. AI Sound Boost continuously analyzes audio in real time, optimizing performance for powerful, dynamic sound with very low distortion, even at maximum volume.
Touchscreen control and party features
As the first PartyBox to feature an integrated touchscreen, the JBL PartyBox Ultimate 2’s volume dial doubles as a touchscreen controller, providing instant access to music, lighting and key settings, including the current song and active lightshow. The speaker’s next-generation PartyBox lightshow combines dynamic ripple effects, multilayer lighting and bold floor projection that fills the room with striking visuals.
Built-in EasySing AI Vocal Removal instantly transforms songs into karaoke-ready tracks and works with JBL EasySing Mics, while a selection of party games adds extra entertainment. Despite its power, the JBL PartyBox Ultimate 2 is designed to move with the party, featuring larger, sturdier wheels and an ergonomic handle for improved transportability, alongside an IPX4 splashproof rating and a housing made with recycled materials.
