K so in the future (not anytime soon) i plan on buying a PA system for my bands so we don't have to rent equipment so we only have to pay for renting/insurance costs at shows. I was thinking about buying this mixer because i am familiar with it http://www.musiciansfriend.com/pro-audio/mackie-cfx16-mkii-mixer and i noticed when i was looking for speakers that they were powered or unpowered. Now from what i understand, if i buy a set of speakers that are powered, i don't need to buy a power amp with the mixer, but if i buy unpowered speakers, i have to buy a power amp correct? Also sorry if this is the wrong forum it seems like the best place for this.
yup, you're right. and this is the right place.
punk isn't dead, it's always smelled that way.
