what speakers do you consider "energetic"?

not sure I can even quantify the term , but as you personally define it , which brands/ models would you say have a lot of "energy" ?







Fully horn loaded(including horn bass) speaker systems have an energy that I don't believe can be matched by direct radiators.  Needless to say I have such speakers but in the past I've owned and played sealed and ported box speakers, ESLs, Magnepans and others.  Thus I have a standard of comparison.
