Why Do Martin Logan Speakers Lack Dynamic Energy?

Martin Logan speakers have a huge open soundstage, vivid midrange and excellent detail, better than some of the best speakers in the world.

The only thing that most Martin Logan speakers lack in their respective price range is dynamic energy. What I mean by dynamic energy is sonic weight, mid-bass slam and movement of air that only cone drivers seem to produce (unless you're talking about the Martin Logan Statements). Speakers like Wilson, Revel or Aerial Acoustics have great dynamic energy, so why can't Martin Logan build a speaker cheaper than $80,000 that has it too?
