As one who manufactures both home audio and pro audio speakers, and does so with pro audio drivers, in my opinion they are not necessarily whole different ballgames.
One reason to consider speakers that use prosound-type components for demanding home audio use is the freedom from thermal compression. Thermal compression occurs as the voice coils heat up and the resistance rises, and can rob speakers of two or three decibels on peaks. This compression of the peaks reduces the liveliness and emotion that should be in the music, because musicians use dynamic contrast to convey emotion. Typically mild thermal compression sets in at about 1/10th the rated power, and by the time we get to 1/2 the rated power it's pretty severe. By using drivers that will be seeing less than 1/10th their rated power under home audio conditions, we preserve the liveliness in the music.
However if you do not want prosound components, the Legacys you mention are a good candidate.
