Are you looking to fill a room or just desktop use? Is option for later subwoofer an important consideration? At this price range you're barely getting beyond "computer speakers", quality of sound/build is bound to suffer (4 amps, 4 drivers, 2 cabinets, plus markups). I find this an "exercise in futility" (constraining price/unknown objectives). Recommend looking at "powered" versus "active" to conserve quality and give up on the superior concept.
Powered compact 2-way options (at slightly higher than sought after prices):
Audioengine A2+ ($250/pair, includes DAC, lots of reviews)
NuForce S3-BT ($300/pair, advanced Bluetooth input option, smooth warmth, pristine highs)
PSB Alpha PS1 ($300/pair, subwoofer output, clean/clear/delicate sound, reportedly used by Paul Barton himself)
Beyond these prices the options for better build/sound quality expand greatly.
