<font color='#000000'>Lets also not forget that just because a speaker measures well in an on-axis nearfield situation, doesn't necessarily tell you how it plays into a room. You can measure identical nearfield response of two different speakers, but how they ultimately play into the room can be another story.
Compression is also another very important metric to consider, as well as distortion.
Unfortunately loudspeakers are the hardest audio devices to correlate sound with measurements as there are too many complex factors, as well as personal preferences. Its tough to measure, and even tougher to design right. I don't envy loudspeaker engineers.</font>
