Expensive, but surprisingly good

We have a couple of sound systems, including a nice 8kW custom built system and a pair of Mackie Thump 15s, but we wanted a smaller battery powered system which was easily portable for small or outdoor events. There were other cheaper products but for various reasons we decided the S1 Pro was a good fit for our needs. I was sceptical about the sound quality, particularly how much volume and how much bass would be possible with a 6" driver, but this box is surprisingly impressive in both these regards. Great battery life too. Perfect for when you decide you want to have a spontaneous dance jam for 20 to 30 people or suddenly need amplification for a mic or want just to plug in the projector and show a movie.
