Monkey, I bought and tried the actives in my (very small) home studio, and they didn't cut it for me. Different strokes. I returned them and bought some M-audio BX5s, which work very well when combined with a small sub.
There's a new version of the Alesis (active and passive models) just released, though, which runs about the same price as the older model. The new active model has some helpful EQ switches to adapt it to a room. Do a quick search if you're interested.
Best,
J.
