Great Prices and Great Experience
"I’ve purchased two TVs through Greentoe, and both experiences have been excellent. Best prices I could find anywhere, and both TVs were delivered right to my door without any issues.
My only mistake was forgetting that Greentoe offers a lot more than just TVs! I recently purchased applioances elsewhere and afterward realized I should have checked Greentoe first.
Greentoe will definitely be one of the first places I check before making a major purchase. Let's get the word out, and let the free market dictate prices. Craig Barton Scottsdale AZ"View article

This is the best Bluetooth speaker I've ever had!
[This review was collected as part of a promotion.] The JBL partybox ultimate is an absolute crowd pleaser. Im a fan of the design quality and feel/look the power of bass you not only can hear but feel and the lights are I think the best I've ever seen on a Bluetooth speaker. the sound is phenomenal, and highs and mids are amazing I absolutely would recommend the party box ultimate to anyone who loves to dj and partying all night long, And to just sit back and relax and enjoy blown away! sound. Cons. I wish it came with a branded JBL dust cover that would be cool. The box art that JBL uses is still my favorite. the only thing I was worried about when I opened the box I noticed the box was cracked from shipping and handling thankfully nothing got damaged very happy about that.

JBL Beast
[This review was collected as part of a promotion.] Peek the dimensions…this is no small speaker! It definitely delivers on some booming sound! It’s great for backyard BBQs and great for basement hangouts with the light show it gives- which is fully customizable with the JBL One app. You can actually turn all the lights off if you’d want to utilize it at home without the distraction. My nieces had a lot of fun hooking up mics and singing along to music. There’s also a cool little cubby in the back for cord storage and some wheels to move this beast around.

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!!

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.

MONSTER SPEAKER
[This review was collected as part of a promotion.] Well first and foremost, this speaker is an absolute GIANT! It’s about 41 inches tall and is fairly heavy in weight but the good thing is it has wheels so u can roll it around instead of carrying it everywhere. Aside from that, when i say this speaker bumps, it BUMPS! Its so loud it lights up a football field. Speaking of lights, the light show on this speaker is insane with so many options. You can also use it for Karaoke night because it has a microphone port and also has a guitar port if you need some type of amp. It also has a “partypad” which allows you to DJ a little bit and play around with different sounds all controlled through the app. Overall i am extremely happy with this speaker and am very excited to use it every chance i get.

Can I connect JBL 1000 watts subwoofer to this party box
Asked by: Paul
The PartyBox Ultimate already has built-in subwoofer and it does not support connecting an external subwoofer. The PartyBox Ultimate's connections are limited to a 3.5mm audio input, Bluetooth, and Wi-Fi. There is no RCA output or dedicated subwoofer output listed anywhere in the specs of the current model.
