Has anyone got some suggestions for drivers specifically for a keyboard monitor (or maybe as a PA set up for small-ish venues?). This is to be a gift, and although I've build some home diy speakers that turned out well, maybe there are instrument monitoring specifics that I should consider. I looked at a few commercial types, but they seem to be a single large driver.. no tweeter??? can that be right? Can I do better?

Any suggestions appreciated,
