Customer Ratings & Reviews

In my opinion, the JBL PARTYBOX ULTIMATE 1100W is an impressive speaker. It has bass, midrange, and tweeters, producing unparalleled sound. The volume is perfect in every aspect. It's highly recommended for any occasion and is my favorite of all the JBL speakers.

Very nice and loaded and very loud bass on top Very good speaker

This speaker is all you need to party. Loud, clear, tons of bass and has Chromecast which was a must have for me. 10/10 on this one.

Great sound kind of heavy good base.  but you have to subscribe to their music platform.

Truly is an ultimate speaker! It has both sides of the world- you are the DJ with a clean system ( all in one- low, mid, high speakers) at on the fly. 1 is excellent by itself, 2 would be the ultimate dream.

For residential home use, the Partybox Ultimate is ultimately going to get your neighbors’ attention! Wow, great sounding speaker with full range of highs, mids, and lows at any volume!

This is the best speaker jbl has made super powerful and quality sound thanks best buy for the awesome product.

Ok speaker but at the proce 2 partybox 710 are way louder better bass and cheaper only good upgrade really was light show i say my partybox 1000 even sounds better and more bass

I highly recommend this partybox if you have the extra cash to spend. Super loud, bass is amazing, and the lighting is out of this world for a party box. Cons: Its on the heavier side so going to need a friend to help carry. Its called a portable party box but its not really portable. Going to have to plug it up to use it unlike the party box 310 and 320. Other than that the speaker is amazing. Used it at my brother's wedding and a lot of family and friends really enjoyed it.

Its so good we live in a 1 acre and we could hear it nicely thought the land.

I am happy with my spiker very good quality and very clear voice I am so glad

Great sound quality, very loud, and easy to move around with the built in wheels.

Quality and sound amazing no other soeaker compares to the jbl ultimate

This product is amazing. Best sounding speaker I’ve heard yet. I love the LED lights that displays all around the speaker. Well worth the money

The partybox ultimate bass is unreal , like taking thunder in a box with you . I have 2 partybox 1000's which is crazy loud , but the ultimate is king . Purchased a 2nd ultimate jus waiting on UPS truck .

This speaker is definitely the best, sounds really good and easy to use! Was on sale when I'd get it!

Love this speaker! That bass slaps you across the room

If you’re looking for bringing fun with you this is the one thing that is a must! My family loves this great addition for parties and around our pool.

Nice quality, great box to invest in i gave me a wonderful party

This this speaker bumps, I used it for an outdoor party and received a bunch of compliments and people where very curioso about it. The bass is awesome and no distortion in the sound when we played it very loud
