Budget Powered Speakers

I will try to steer away from powered speakers, simply because the electronics take up cabinet volume that could otherwise help produce better sound. With $500, you could easily get a capable all-in-one amp (like the Wiim Amp, $299), a pair of wonderful passive speakers (like the Sony SSCS5 M2 2025, $178 on sale) and a pair of good speaker cables (like Micca 14 Gauge 6.6 Feet Each for $26). My sons have a combo like that, and they love it. This combo could really render sweet sounding with airy top and nimble low ends.

I could not disagree more @lanx0003 

He was not asking for an ultra low end system/massive compromise.

I've had my Audioengine A1 with a simple 8" sub for several years and have been super happy. They are well reviewed, been around a long time and have all sorts of models to fit your budget

These would be perfect.
