Big Sound

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

The booming sound out of two 15” better then Sony

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

More thunderous clarity than I had hoped for.

I am absolutely amazed at how thunderous and clear this this is. I want another one, just waiting for it to go on sale again. For the price I originally paid. ($374)

Don't buy!!!!!

Sounds like the music in my car, I wish the volume was more plus it's extremely heavy. I don't recommend I should have spent another $300 for the jbl 720 but will return.

Very limited controls

Its great for music for large areas.. but theres no way to control bass individually, so for a tv your at the mercy of the basic controls, i didnt like it when hooked up to a tv

Love it!

Love it! I was looking for not just an event machine, but a play my music in the house loud machine and this did the trick. No need for 5 or more speakers for a full system. Just simply wifi your phone and play your list. It's perfect. We rocked the house for hours tge minute we unboxed it. I can't wait to use it fir our Christmas party, where we can use the mics just to talk and also for karaoke.

they forgot a battery .

I did really like this radio it was heavy well built well put together but they made it look like it's portable? it is if you carry a generator and an extension cord with you then you can take it wherever you want that's the reason I took it back to the store. that was the one deal killer for me. now I've got to go back and try to find another one that has everything including a battery that will play when I'm out somewhere without a generator.
