    The speaker is huge! The lights really put this speaker together especially on late nights, gives off a new ambient lighting. Worth it, just very pricey.

    I have so many bluetooth speakers. but this is the best sounding one that I have heard in long long time. Very immerseful. Fills up the room from wall to wall. They won't say what the wattage is on this speaker, but i'm sure it's in the hundreds. And that doesn't really matter anyway. It sounds great , and has plenty of power. Bass sounds great. But it's not overwhelming. Still allows you to hear the instrument separation. I bought the a c version because I didn't want a battery. A speaker this big doesn't need to be moved around anyway.

    Well rounded Party/Multimedia speaker with battery

    A well rounded, robust, sonic speaker. Has good high, mid, and low, with some good infrasonic feel. Easily adjust sound frequencies with app. Yes, you can get some good infrasonic "feel" with these 12x12" subwoofer. When not in use at parties, you can use these as a dedicated subwoofer at home for watching movies. Wirelessly if you have a wireless audio adapter. Also get that infrasonic feel when watching movies. Only down is that the system is not IPX4 rated over all and lighting is subjective (I like subdued lighting). Also the app is a little to nosey for a speaker, but works well. It's not the best at everything, but good for everything.
