so i need a setup for playing live gigs in very small rooms to very small groups of people. I'm just running a microphone through a pre-amp (dbx mini-pre) and my sounds have a big dynamic range. treble is most important, but bass capability would be good. i was wondering if it was possible to power a bookshelf speaker with something like this: (pyramid pa105 60 watt microphone PA amplifier w/ 70V output -- i can't link since this is my first post... but i did search!). would something like that work and give me enough sound to work with?
