There are so many choices i powered speakers its crazy.
Mostly price will determine quality but don't forget to look at the inputs, do you need an external mixer, and weight. Behringer has upped their game and is a good middle of the road brand. If you don't want to spend a lot Mackie is having a rebate sale on their Thump Series.
If you want to go unpowered look at the Carvin XP800 powered mixer ( 12 lbs. 500 watts ) and their moulded cabinets. They also have a powered moulded cabinets with three channel mixers built in and for the money I think they're the best buy out there.
If you want to spend more there's plenty of upper level speakers out there from EV, JBL, Yamaha, ETC.
