I watched the reviews online. They cannot describe how loud and powerful this ultimate party box is. The bass is amazing. It literally vibrates the walls in my house. You can feel it in the countertops, feel it in the foot rests when you're on the couch. It is amazing. You can turn it up to 100% volume and it will still be clear (no distortion). The light show is great (I wish it had more lights, but I didn't get this for the light show). I can't speak to the karaoke or using it as an amp for a guitar, but I like that there's functionality to do that. Some people will frown on this due to the lack of a battery so you can't take it anywhere, but honestly, I see that as a plus. Anything with a battery is doomed to fail in a matter of years (phones, cordless tools, laptops, and even cars). This will never fail you. My solution was to buy a power bank that has over 1000wh to power it. That can be replaced at a cheaper price than the entire unit. Plus, this thing already weights 87 lbs. I can't imagine having a battery to power it inside the unit. Sheesh. I hooked it up to Google Home so I can use it as a speaker in the house. You an hook up to 3 bluetooth devices to the speaker at a time (my phone, my wife's phone, and our home computer). 10 out of 10.

Very loud but,,,!,, very clear,!,,

Good Quality, great lights and highly recommended for party.

These things are pretty ridiculous in a great way. Super loud and crystal clear.

This is everything and more than I wanted. The bass in this is a thing of beauty.. Expensive I got it but if you want a heck of a Bluetooth speaker you can't get any better and it's worth it, trust me. Two Cons . Its heavy and second has no battery, so has to be plugged in at all times. That's it..

Dry nice sound

Before I get to my review, let me tell you a story. I had purchased a Partybox 710, a few months ago, which initially blew me away. I was so impressed I started looking to get another one to make a stereo pair. I then made a big mistake by watching a comparison video of a 710 vs Ultimate. The power and clarity of the sound seemed too good to be true. I then decided I would have to hear the Ultimate in person before I get another 710. One listen of my favorite track and it was written: I need to stereo pair the Ultimate. Luckily there was a sale so I was able to snag two of these and the rest is history. I now am the mayor of my block. These speakers are game changers for how quick I can roll them around for multiple occasions with friends and family. It even works great with AirPlay so I am using it for audio on my Apple TV. The light show is also a treat! If you have some color lights that can match with your music, the disco ball will drop. If money is not a major issue, I recommend you snag two of these. One is also great, but having a wider soundstage with two of them is an experience.

Click to play video So, I got two of these bad boys... Yes, they're loud, overwhelmingly so like PA speakers (better for parties/events (maybe 100-150+ people) then for personal listening IMO). There is an nicely designed app you can control EQ, Lights, and Mixer. Connectivity: you can do stereo mode where it plays left and right speakers if you have two speakers, and there is party mode to connect two speakers but play mono audio. You can connect audio and be separate from your phone audio and an app's own audio so that is good for multitasking. The apps takes a bit to get used to, but once you do it's very easy to navigate and use! Pros: [+] It has dual woofers, dual tweeters, and new mid-range drivers for better sound detail. [+] LOUDDDD, like using the speaker(s) outdoor will make your neighbor next-door mad, and the 15 other neighbor after that and so on... [+] Good app features, EQ, Lights, Stereo Mode, Party Mode, and Even Mixer Mode... [+] Flashy RGB lights, customizable. [+] On the back has cord holders, battery plug in, and aux connections for daisy chaining two speakers or guitars and microphones. [+] Has Wheels and Handle for easy carrying of this big boy. Cons: [-] The bass is more floor shaking they're in your chest unless your right up to it... [-] Requires Wi-Fi for essential things like Sync and Lights. [-] EXPENSIVE, and this is self-explanatory as this speaker can cost $1,000-$1,700+ USD... [-] It's 80+ lbs so it's heavy, and even with the handle and wheels can be quite the arm workout to carry around, so it's not that portable and there is no battery so it has to be constantly plugged in.

Es una bocina genial se nota la diferencia respecto al modelo anterior, una excelente compra!, ampliamente recomendable.

Caixa espetacular. Som alto, potente e de ótima qualidade! Sem contar os jogos de luzes que é um show a parte.

the Best and the house is shaking. It has the Best Bass of all the speakers in the market

Excelente para fiestas, sonido impresionante. Calidad de audio queda a deber, debido a que solo se puede escuchar audio en mp3

Click to play video Me impresionó su calidad de sonido y su enorme potencia lo vale cada centavo de su valor estoy fascinado!!!
