1,100 Watts of Pure Partying Power

Let's face it: most small-scale Bluetooth speakers aren't designed to cut it at larger events. Enter the JBL PartyBox Ultimate, a 1,100-watt speaker fit with dual 9-inch subwoofers, powerful midrange drivers, and a crystal-clear tweeter, optimized and designed to ensure your next get-together is filled with immersive sound. Simply connect to the PartyBox Ultimate via Bluetooth or Wi-Fi (Dolby Atmos Compatible) and access the onboard PartyPad to dial in the perfect amount of oomph for your venue. No need to set up any external lights, either; the PartyBox Ultimate comes with a customizable built-in light show, offering energetic visuals synced exactly to your music's tempo. Topped off with impressive multi-speaker connectivity and instrument inputs for even larger performances, the JBL PartyBox Ultimate will ensure the party keeps going all night.

Your sound, your way

Take full command of JBL's Original Pro Sound with the PartyBox Ultimate's robust user controls. The top panel features JBL's proprietary PartyPad, making several effects and transitions available in three simple fingertip controls. You'll also have access to Mic, Bass, Treble, and Echo EQ options to dial in your sound to perfection. Deeper levels of customization can be accessed via the JBL One app, including light show color options and advanced equalization possibilities. In the mood to practice your instrumental skills? No problem: given the PartyBox Ultimate's dual mic and guitar inputs, plugging in for a friendly jam session is as easy as pie.

Built to handle the rigors of your rave

Once the JBL PartyBox Ultimate gets started, there's no stopping anytime soon. Durable build materials and onboard IPX4 splash protection make this speaker a great addition to any outdoor or poolside environment. No matter your distance from the venue, the speaker's built-in handle, wheels, and cable compartment provide an easy travel and transport option — not to mention a handy storage device for any additional gear.

What is Certified Open Box Gear?

At Sweetwater, we're so picky that what we call "Certified Open Box" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

Certified Open Box (also known as a demo) means we’ve had it out of the box for our YouTube channel, displayed at events, tested in our studio, or maybe it was in a customer’s hands for a few days and isn’t ‘factory fresh’ as a result. Every Certified Open Box item we sell has Sweetwater’s 2-year Total Confidence Coverage™ warranty and has been tested and verified up to ‘new’ specs by our factory-authorized technicians to make sure it’s in perfect working order before we ship it to you.

When you buy a Certified Open Box item at Sweetwater, you get:

2-year Total Confidence Coverage Warranty™!
Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!

Hands down I've yet to find a more responsive Bluetooth speaker. This thing bumps and the low end moves through you. Whether you're dancing after hours or working in the yard, you can thoroughly enjoy any genre. For sure this speaker is a crowd pleaser.

However, the wheels on this are not adequately sized. This thing is a beast and around 75lbs. The speaker is difficult to move and best suited to stay in place. I've had plans to create a mobile cart or dolly to move with bigger wheels which would give it better mobility. I tipped this bad boy over this summer and I think I need a new top panel. I miss my best friend, JBL.

Also noting, the cord falls out pretty easily and the speaker shuts off and you have to wait for it to reboot. The lights are a bit much for me and I prefer just the black. I've used this for karaoke, projectors, TVs, and makeshift late night raves. I've also used it to run instruments through it for band practice and shows. I was also able to wire it into my PA system.

I LOVE IT! - anyone have ideas on how to go about fixing it or replacing the panel, be stoked to hear it one more time. I'm thought about dismantling it so I could bypass the computer and run it with an headphone jack. I couldn't figure it out at the time.

I have had the party box ultimate for almost a year now and the quality is legit. Highs, mids and lows are all on point. I was really surprised with the sound of the base. It is quite heavy but I rarely move it around. It's loud enough it covers my whole 22 acre property. I honestly don't have anything negative to say about it and the Sweetwater customer service was fantastic. Highly recommend.

This partybox is a cut above the rest a complete component style system.Bass is outstanding midrange and tweeters are exceptional. I was leary of purchasing this but after I heard the 710 partybox I was glad I did.

Bought this speaker and am so impressed with the sound quality. The best way to listen to this speaker is through Tidal and use WiFi and you will here an amazing difference and quality and bass that will blow you away!!! To get the most out of it though you must have a paid music service that streams high quality music through WiFi. Tidal Connect is the way to go. Trust me you won't be disappointed you will love this speaker and what it has to offer. Don't even get me started on the light show and all the different light settings you can change!!! Plus it's been updated 2 times since I've purchased it. Has room correction and everything for the sound to sound the best wherever you place the speaker!!!!

Already have the Party box 1000 and thought how could it get better and then the Ultimate comes along all I can say is it's an amazing speaker experience all together!!!! Sounds amazing highs are crystal clear and the bass shakes the whole house or area that your in. Get one I recommend this speaker to everyone that's looking for something amazing to have!!!!!
