JBL PartyBox Ultimate Wi-Fi & Bluetooth Party Speaker – Black

The JBL PartyBox Ultimate is the most powerful and most complete party speaker JBL has ever built. Delivering a staggering 1,100 watts of room-filling sound through dual 9-inch woofers, 4.5-inch midrange drivers, and 2.75-inch tweeters, it brings professional concert-level audio to your living room, garden, or event space. Whether you are hosting an intimate gathering or a large outdoor party, the PartyBox Ultimate commands every space with authority and presence.

For the first time in the PartyBox series, the Ultimate supports Dolby Atmos over Wi-Fi, delivering a three-dimensional, immersive audio experience that surrounds you with sound from every direction. The self-tuning system automatically analyses the acoustics of your environment and optimises the speaker output for the best possible performance wherever you place it, ensuring every playlist sounds its very best.

Multi-Dimensional Lightshow

Beyond the sound, the PartyBox Ultimate transforms any space into a full sensory experience with its spectacular multi-dimensional lightshow — the biggest and most elaborate of any party speaker available. The show features a mesmerising starry night effect, dynamic light trails, powerful strobes, and lights that project patterns onto surrounding surfaces. Everything synchronises automatically with the music, or you can customise the effects using the JBL One app to match the mood of your event perfectly.

Connectivity & Inputs

The PartyBox Ultimate connects wirelessly via Wi-Fi 5 GHz/2.4 GHz and Bluetooth 5.3, with full support for AirPlay, Google Chromecast, and Alexa Cast for seamless streaming from any device in your home. For live performers, it includes dedicated microphone and guitar inputs so vocalists and musicians can plug in and perform without additional equipment. A USB input, auxiliary line input, and the JBL One app give you complete control over every aspect of the sound and light experience from your phone.

Built to Party Anywhere

With an IPX4 splash-proof rating, the PartyBox Ultimate handles spills and light rain without missing a beat. Its wide, sturdy wheels and ergonomic handle make it straightforward to move between rooms or transport to outdoor venues. At 39.5 kg it is built for permanence and presence — this is a speaker that makes a statement wherever it stands.
