A small nearfield audiophile oriented monitor may sacrifice the ability to to play as loud, for a greater accuracy to detail, resolution and frequency accuracy.
So you will have differences.
Generally, those who argue that PA speakers are (or should) be the same as High End Audiophile speakers fail to recognize these differences in applications.
Like putting a V-8 in a VW. Great at the drag strip, but not so great driving the new GF on a spirited Sunday drive through some challenging country roads.
