Thanks guys.
I am thinking of getting one of these systems with everything included... and easy to carry around. I do not fancy using 50 kg speakers anymore
So, I guess, I would like something like StagePass 600, seems to be nice, clear, loud enough, light weight. But it seems they have not upgraded the model for quite a while now. And in some cases, like the big Thomann company does not have them in stock anymore.
Because of that I was also wondering what alternative might be out there, but in the same format... Small powered mixer, small speakers, but suitable for an arranger keyboard gig.
