Speaker Hammers!!!!

An amazing speaker!!! It just hammers!! the bass is amazing. I love it so much I bought another one and am selling my current stereo system. For people that like extremely loud music with excellent clarity and deep bass, I highly recommend this speaker.

Loved so much we bought a second!!

Sounds just like you're at a concert big volume awesome lights we do weekly bonfires with music and karaoke. This is a must have for any party typically you don't need two of these… we are just over the top people and absolutely love these speakers on both sides of our waterfront property

It's Loud!

Loud and great sound! Not battery powered will need a plug, but the screen on top makes for easy use and control.

LOVE IT! I caught it on clearance for $319 after waiting patiently for it to go on sale! I absolutely love music and this gives me what I need to stay happy. It's loud enough to cover the entire house and I don't have to keep moving it around to hear it like the smaller speaker I have.

WHAT AN ABSOLUTE UNIT!!!

I dont know where to even start! This thing absolutely shakes the roof off my shop. I was very skeptical after reading some of the reviews but after doing some simple tuning on the speaker and my phone it sounded absolutely amazing. Treble and bass are top tier for the price. This thing is HEAVY and built to last. very easy to move around with the wheels. I am 6'2" and it comes all the way up to my chest in height. Dont let the negative reviews turn you away. I am beyond happy with this unit. REMEMBER THIS IS NOT BATTERY POWERED AND IS REQUIRED TO BE PLUGGED IN AS STATED IN THE AD. Which is exactly what i wanted. 5/5 stars easily.

Brand name says it all!

This speaker truly is a monster. I picked this one up this morning to add to my collection because why not. I have the x6 and the smaller rock and roller. I have used both of these for several applications and love them both. I am testing out one of these GI30 to see if I will purchase more for a large outdoor business venue. After unpacking I was very impressed by the looks and also it being very heavy. This cabinet is not made out of cheap lightweight wood products. Once I turned it on and cranked it I was immediately impressed with the volume capacity not completely being limited by its power. Once I took a walk about to hear the quality and range I was also impressed with the high end crisp and clear sound it provided. On the low end the bass also was equally impressive. In a previous life using pro audio and being old school as I am without the new technology I am amazed with these for the average joe that knows nothing about sound. These will definitely wake your neighbors so be sure to invite them to the party!

Holy Spirit Activate!!!!

I literally just bought this. It sounds amazing exactly what I was looking for in sound. Extra bonus it comes with a mic. karaoke nights about to be a blast. It's big sturdy but easy to move around that God it has wheels. It's a great addition to my household. So glad I got it. It's loud I mean party worthy house party club worthy loud. My dog ran when I turned it up and I didn't go as far as it could lol 10/10

Meehhh!!!

This speaker definitely had me fooled when trying it out in store. Initially was super impressed with the sound quality, especially how the sound radiated throughout the warehouse. My wife even said she could hear the music from the other side of the store. After looking for reviews online prior to purchasing, I was left disappointed other than a few which didn't go into detail. I'm not a hard-core audio guy, but I do appreciate decent quality. When used on your phone this thing produces the sound I heard in store minus the mediocre bass. If your trying to use this connected to your t.v for surround sound like I was, prepare yourself for disappointment. Don't know what this issue is but for some ungodly reason this speaker produces shameful sound if not hooked up to a mobile phone or tablet. My tv on it's own was louder than the speaker when using for surround sound. Just saying for 500 big ones I at least expect the sound quality to be neutral across the board regardless of what I'm connecting it to via Bluetooth. Will i keep it? Probably not, it's cool to have, but not 500 dollars cool unless your using it just for music from your phone.

Good but not great

It was louder in the store. I didn’t realize it needed to be plugged in at all times so that was a negative for me. It still has a good sound but the lights aren’t as vibrant. Overall it is a good item but could have been cheaper.
