The booming sound out of two 15” better then Sony

Very loud and added a external powered sub woofer which made sound even louder

Big Sound

Big sound comes from this speaker. It is heavy but you get the wheels. Great for any event.

Looks good, easy to use for beginners.

For the money, we can get a more sophisticated speaker. Controls we limited.

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.
