Electro Voice Stage system 200 was great for its time (maybe 25+ years ago?). It was pretty lightweight and affordable stage amplification, and to get more neutral sound out of it, you could hook up an external box that provided a factory-defined fixed EQ to give it its best sound (there's a switch on the back to set for whether or not you have the EQ). So first, if you don't have their dedicated EQ box, forget coming anywhere close to the neutral sound you'd need for a quality piano reproduction. (Even with the box, I'm not sure how it compares to what's around today.)

Your Fender cabs are also not designed for accuracy. Really, nothing designed for guitar or bass is likely to work well. Guitarists and bassist usually pick the amps/speakers they do because they like the way they color the sound. For piano, you want something that doesn't color the sound at all. People sometimes do add bass cabinets to their main speakers for more low end, but it's not just a matter of adding a speaker, it needs to be smoothly integrated into the rest of the system, typically with an electronic crossover, which doesn't merely add a speaker for more bass, but also filter that bass out of the main speakers (rather than duplicating it) and providing a smooth sonic transition between the two.

I've never heard the Nord speakers. Though for solo playing at home, the idea of looking for that general kind of monitor may be more desirable than sticking with speakers designed for PA use as has mostly been mentioned so far. If you're playing in a group situation for your rehearsal room scenario, and you find the QSCs too big/heavy, check out the Electro Voice ZXa1, they still sound really good, and they're only 19 lbs each.
