Whoops, I forgot to say that, when I don't use the speakers, I use a set of Alclair Audio Spire in-ears. They are a 6-driver set that sounds wonderful and, with the custom molds cuts ambient noise more than the ear plugs/shooting muffs I use while shooting.
Using them on stage, I have the volume set lower than what you can hear in the house and still have perfect clarity for the other instruments and voices.
