I see some 4430's going for ~$1500 which seems to be about the going rate for nice L250's and considerably less than L300's. How does the sound compare to the home models? Are the 4430's really in an entirely different league? Are they more of a rock speaker or do they work well for all kinds of music?
Being Professional Series the 4430's are more industrial looking and therefore might not be as suitable for many home decors, but if the price is right and they really kick butt, I suppose that fact could be overlooked to some extent.
