JBL PartyBox Ultimate: The brand’s new beast with 1100W and Dolby Atmos

JBL is expanding their party speaker lineup with the introduction of the highest performance models yet. The JBL PartyBox Ultimate, a speaker packed with features to take your parties to the next level.

This speaker was officially unveiled on August 30th of this year at the JBL Club event in Berlin, Germany, which we were lucky enough to attend. We were able to see it in action and without a doubt we found it to be an extremely powerful sound system, with a thundering bass and we are sure it will delight anyone looking to throw a big party.

We talk about a speaker with considerable dimensions, so it is intended for use outdoors or in rooms with significant dimensions. In a normal house or if you have a small garden, you can use the smaller PartyBox models like the PartyBox110. But if you want to use it in a venue or in a large room or in the open air with a large number of people, this is the perfect speaker.

Next, let’s take a look at the features of this new JBL PartyBox Ultimate speaker so you can get to know it better.

Bass-heavy sound and immersive audio with Dolby Atmos

The JBL PartyBox Ultimate delivers powerful, crisp sound with JBL Original Pro Sound technology. It features two 4.5-inch midrange speakers, two 2.75-inch tweeters and a pair of 9-inch subwoofers. This configuration gives you an exceptional sound with incredible bass power. If you like to feel the bass in your chest, we guarantee you will with this speaker.

Although the audio content in Dolby Atmos is not yet very extensive, if you have a premium account on a streaming audio platform such as Amazon Music Unlimited, Tidal HiFi Plus, or Apple Music, you will be able to access a catalog of songs in this format.

“With our biggest addition to the PartyBox family, we’ve created a speaker that combines the best sound with an immersive light show. We’ve also incorporated technologies like Wi-Fi connectivity, auto-tuning and Dolby Atmos to deliver a superior experience”.

Carsten Olesen, president of Consumer Audio at HARMAN

As we’ve said several times in TV & Hi-Fi Pro, Dolby Atmos is a completely different experience from watching movies. In this case, which is primarily for music, it’s the same. The immersive listening experience gives you 3D spatial effects and immerses you in a very different feeling than conventional stereo sound.

Although this type of speaker is always focused on delivering a very powerful bass, the truth is that with two midrange drivers and two tweeters, you can enjoy all the details of your favorite songs without the bass completely masking the other frequencies and losing definition.

More speaker connectivity and integrated Wi-Fi

During the event, several PartyBox Ultimate speakers were linked together with other models in the range for the session of several DJ’s who were playing music, and the truth is that it filled the whole party room with sound. You can wirelessly connect multiple PartyBox Ultimates or other compatible PartyBoxes to multiply the power when you need multiple speakers for an important event.

The wireless connection and the ability to connect multiple speakers is easy to set up and customize with the JBL One with the JBL One app.

Wi-Fi and Bluetooth connectivity let you enjoy your music in high definition wherever you go. The Wi-Fi connection ensures uninterrupted playback, even in the middle of phone notifications. Or, if you prefer Bluetooth, you can enjoy seamless audio indoors and out. The JBL PartyBox Ultimate automatically adapts to your environment every time you turn it on.

An impressive light show

Another key feature of the JBL PartyBox Ultimate is its lighting effects. You can choose from several lighting modes to turn any room into a party. With a multi-dimensional light show that includes starry night effects, light trails and dynamic flashes, you can customize the ambiance to your style and enjoy a unique visual experience while listening to your favorite music.

Interactive party

Another highlight of the JBL PartyBox Ultimate is the JBL PartyPad™. This is an interactive panel on the top of the speaker that lets you create DJ-quality sound effects all night long by simply touching, holding and sliding your fingers.

This speaker also features dual guitar and mic inputs, plus karaoke equalizer settings for when you hit the stage.

Water resistance

This new Ultimate series, unlike anything we have seen before, comes with IPX4 water resistance. This means that you can’t submerge it (something we don’t think you’d think of doing), but it can withstand splashes. As a result, you will be able to use it near the swimming pool and if it does get a little wet when someone jumps into the water with a splash, it will still be able to function. Keep the port cover closed so that no water can get into the ports.
