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.

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.

Very loud if you stream from iphone or mobie.

Update 9/21/2024 This is a 5 star speaker. To get the full extent of the speaker you must download the Monster Zone app. In the app you can control all light settings and EQ. You can also do this on the back of the speaker but it is cumbersome. This unit does have a bass boost button on the back which produces a deep rich bass. However the bass boost button did not function in the app. Maybe an update will fix that. Bluetooth sounds the best from your iphone or mobile device. Initially I was using the echo Show 15 which produced sound at a very low volume. When I switched to my iphone it was rattling duct work in my basement and scared my cat half to death. I do recommend this speaker and it is worth every penny. This is not a 5 star speaker. I am generation X where we put subwoofers in our cars that made the windows shake and near by car alarms go off. I will go over the pros and the cons. Lets start with the pros first. Good looking massive speaker with 2 subwoofers. It is about time somebody had the courage to make something like this. You can sync two speakers with the TWS button. Good clear sound. The cabinet design looks awesome. Next are the cons. It does not have a bass boost button. I have single ion speakers that produce more bass than both of these speaker playing together. The LED lights are under whelming. The tweeter has good range but the woofers are very cheap. I wish I could open this thing up and replace the woofers. Over all I think the average person will be satisfied. At $500 each I think they are trying to go after a higher end consumer. You can get a Bluetooth speaker that sounds just is good or better for way less. I was expecting a little bit more for $500. Over all I will keep them because they have a good sound but the bass is a little lack luster because of the cheap paper woofers.
