    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.
