Sinae,
With the caveat that people in threads like this will tend, naturally, to recommend what they own or have owned, if you're interested in the coherence of time/phase aligned speakers, look into either the Reference 3A Dulcet or De Capo. Used, either one should fit into your price range. New, you could swing the Dulcet. I've owned both and they are very sweet. Both are essentially "crossoverless" designs, with only a capacitor to protect the tweeter, and both have mirror imaged pairs and slanted front baffles to aid in time coherence. Worth a listen. There's also the Green Mountain Audio Rio II.
