Monster GI30 High-Power Bluetooth Speaker

These sound good, but are not as loud as expected.

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

Poor radio quality due to cheap antenna

Speaker is good when using Bluetooth. However, radio feature is horrible due to the antenna quality. The antenna is very cheap. Radio sound is poor. Lots of static.

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.
