what speakers do you consider "energetic"?

active speakers

In general electrostatic. Good electrostatic sound like the notes are just springing out of the speakers. A really amazing and unique sound. One I chased for a long time.

Well designed (CD) horns! 😎

Active eh?  wondering, is that a common trait with active speakers?

I did not find my previous LS50w's energetic

very interesting to me also that the first several responses exclude traditional passive box speakers

Those which can reproduce the "immediacy" heard in live music and captured in the best recordings..

Vintage Altec and JBL have a particular synergy with 60's and 70's Rock! That's why I own them!

that word can mean so many things in a high end hifi context, can represent so mnay different sonic presentations

right jjss49,

as stated and acknowledged

ATC. Sounds live at volume.

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.

in lieu of creating another thread, any recommendations/opinions on lively/energetic amplifiers/brands would be appreciated also

Horns. 100+ db efficiency with 100+ wpc amps. Highly energetic. :)
