Definitely the Ultimate!
Having owned this for 18 months, I can confirm that the sound truly is impressive. A good indication of a superior quality audio speaker is if the deep bass remains still, even at low levels, and the Ultimate certainly does. It has pretty much all the volume you could want too, for most homes anyway, and a nice clarity to the sound also. The bass remains strong, even at higher levels. My only gripe is the Bluetooth connectivity - ever since owning it I’ve had to perform a ‘factory reset’, roughy every 2 or 3 months, because the Ultimate will suddenly and unexpectedly lose connection, and you’re unable to find the device you were just connected to again! I always have used the ‘connect to last device’ option, having always played my media via my iPad only, but that makes no difference either; the Ultimate still won’t find the device again, until you factory reset. You can save your settings for the lights and the top panel, and of course having to factory reset the Ultimate loses all of them, so you have to redo them every time.

Incredible sound
Bought it a couple weeks ago. Amazing quality even at higher volumes. Deep deep base. Would highly recommend if you’re looking for top level performance.

Insane speaker.
Genuinely should’ve written a review earlier. I cannot believe how good this speaker is. I don’t care about the price, it was worth every penny. Please get this if you live in a larger house (with good neighbours who aren’t old preferably..) 😅 The noise output from this speaker is phenomenal and i’ve genuinely never heard sound travel so good outside. I cannot say one bad word about this speaker. It may be the best i’ve ever used. Thanks JBL for a top quality product and I plan on purchasing another.

10/10 by far the best all in one speaker....
I have had JBL products for a long time now, starting with the flip 5, boombox 3, and now the party box ultimate. Each upgrade, they got progressively bigger, better, and louder, but the party box ultimate is seriously on another level. I like my music loud with so much bass my head hurts and the ultimate check both of those boxes. I go to school at UCSB and I bring my speaker to all of the functions. With this speaker, you bring the party. Matter of fact I am the party. Also, the ultimate has a bass boost button for extra bass. Combine that with the equalizer on Spotify and the equalizer on the JBL one app = house shaking bass. Im telling you, things will fall off the walls if you are not careful. If you are considering buying this speaker, you will not be disappointed. I highly recommend the boombox 3 (get the wifi so you can connect it to all the newer speakers, including the ultimate) if you are looking for something cheaper. The party box 520 is a great middle ground between the boombox and ultimate. I got it for my dads birthday I will say, the 520 packs a punch and it is much more portable and it has replaceable battery packs which the ultimate doesn't have (need to be plugged in its 1100W XD). if this is in your budget and you love music, BUY ITTTTT!!!!! P.S. make sure to turn off or down the speaker if you have noise ordinances in your area as the cops will in-fact impound it LOL.

Unbelievably wild would recommend buying
I have had this speaker for 6 months and it never seems to disappoint me and makes jaws drop whenever its at party's. Definitely worth buying it has so many cool features and the light feature just looks insane and to this day I'm still blown away by what this speaker can do.

Amazing! one slight complaint
I got this more than a year ago, and honestly, it’s been amazing! I’ve had so many crazy fun times with my friends—like, it’s by far the best one out there. The lights are cool, but I wish you could pick two colors at once instead of it just auto-picking the opposite on the color wheel. More animations or party effects would make it even crazier. Even with that, this thing is seriously awesome—I’ve used it nonstop and it’s been a total blast every single time!

Big sound
massive size and big sound. Only downside is they have to be plugged into an outlet, not battery powered.

Absolutely worth my money
Incredible sound and power, absolutely worth the price for the build quality and the gorgeous lights. Love the sound, powerful yet clear and with lots of equaliser customisation. The lights can also be customised however you want as well as the partypad. I've yet to try connecting a microphone and guitar but I expect those to work flawlessly too like the rest of the partybox ultimate. Absolutely worth my money.

Great sound and power
I bought this monster on Boxing Day, and I’ll never forget that day—it’s become part of the family. Thank you, JBL! You’ve outdone yourselves. 1100W RMS for a home speaker is just incredible. The power and sound quality are on another level. I used to have the JBL Boombox, which already had amazing sound both indoors and outdoors. But this beast takes it to the next level—perfect for a man cave. Absolutely unreal.

Best party speaker on the planet!!!
As an owner of the last monster JBL speaker, the party box 1000, I was doubtful any speaker could outperform that one. Boy was I wrong!! The best way I can describe the Ultimate speaker is Ferocious!! It had the same power output as the old 1000, but it has more speakers and produces even louder and clearer music. On top of that it also has a way better light show! More color, movement, and synchronicity than any speaker I’ve ever seen! The upgraded wheels and handle make for easy movement of this beast, just know it weighs a lot and would be best to have a friends help if you have to carry it. I would give this speaker 10 stars if I could! If you love awesome speakers, go ahead and buy it, you won’t be disappointed!!

Worth the investment!
I bought this speaker yesterday and I was blown away. It is one of the most POWERFUL speakers I have ever used, forget about using it just for your house, unless you want to blow your windows off. I’m seriously impressed, this thing is seriously underrated. The quality and pump it produces is beyond me. You can feel ever beat in your chest
