Just arrived soon installed.The time I started to read the instructions and my 15 year old daughter had already understood the operation and are connected "as" portable on enclosure.The sound is incredible as power. This speaker could easily serve as a sound system for an evening of new an.Le that the batteries or rechargeable is a definite asset as the ability to plug into a computer (cable included) .This product could very well replace speakers my desktop computer, I'm seriously thinking.
