Powered at that point will be a severe compromise. If it were me, I might look for a pair of used Mackie SRM450s. I sold a pair last year in good shape for about $450.
The used Mackies were $225 each .. $450 for the pair. I think you can find similar deals that will sound better (assuming you can hear them first) than a new $250 powered speaker, where you'd be looking at Alto, Behringer, American Audio, etc.
