Musicians and DJs who provide their own backline need a reliable sound system that sets up in a flash and is easily tweaked without a lot of fuss It has to respond directly and predictably to every mix. Live acts need resilient speakers with lots of load handling capacity and the staying power necessary to operate at high levels for hours on end. The rig has to deliver tight, punchy bass response that gets people dancing as well as assertive mids and a sparkling top end. And it has to be easy to handle. The SIGMA line does all this and more.
