Thank you noguud!
It's very easy and quick to assemble at each performance and sounds really good. I connect the 11R to mix console (via Line Outputs) the most of the time. But for small gigs without a good monitor system and sound technician, I connect it to the ART Sla 2 and the 2x12 speakers and it gives me all I need.
