The 2200 uses the older generation (Z-560/Z-680) satellties which had more internal volume, were ported and had better full range response. I would definitely go with the 2200 for sound quality.
It's a shame Logitech has taken a step backwards in sound quality when all its competitors have taken two steps forward.
Anyway, people still buy them because they look cool. PC peripherals to many are a combo of looks and utility, while others are a bit more sound quality oriented and would buy a black cube if it was the new authority in audio (which I have done).
