If only because of the weight, I'm probably partial to unpowered speakers. I'm usually a one-man show and schlepping my keyboard is enough exercise for me as it is. Plus the idea of not having to plug the speakers in seems very convenient. I obviously don't want to spend more than necessary but I'd rather pay for quality than save money and get mediocre sound and reliability. Could anyone give me a primer on how to match a powered mixer/amp with passive speakers? I know how more watts = more volume but that's about it. I'm clueless with regards to ohms, and then I also see how they mention something like "300 watt program/450 watt peak" - what does it all mean? Also, which brands have the best reputation? So far I've been hearing Mackie and Yamaha mostly. Thanks for the help everyone! By the way, I don't need some huge mixer with ten channels - at most I'd probably want it to be able to handle four instrument channels and two singers.
