I doubt anyone other than speaker manufacturers can tell you the relative significance of the figures you are looking at. I also doubt it is easy to quantify in dollars what it costs to achieve a flatter response curve. You haven't said if cost is a factor, you just seem to have picked out 3 speaker lines and thought if fair to compare them on statistics. I agree it's a way to separate the wheat from the chaff but without listening under EXACTLY THE SAME conditions all the statistics become less meaningfull. Many people consider speakers1/2 the price of SLIGHTLY superior speakers a bargain. That's a question you have to answer for yourself.
