When I had my other Tyros I purchased the Tyros speakers and found them to be ok. This time however I think I'd like to get a speaker system that has a bit more flexibility and volume.

Can anyone recommend a solid speaker system that could be used for playing the Tyros through as well as vocals and some trumpet and sax parts?

I also just purchased a GNX4 Guitar workstation from Digitech so if the sound system could also work for guitar as well that would be great. I have a feeling though I'll really need a dedicated guitar amp for best results.

Thanks in advance!
