What would your "perfect speaker" sound like.

What would your perfect speaker sound like. Not interested in the brand, or the a speaker you heard at a friends house or audio show This is a thought experiment. Simply conjur up the most divine sound in you mind and tell us what you are conjuring. 

Please be brief, 


My perfect speaker sounds like a speaker that's true full range and musical.  Just that simple.


"full range" is it a dream a fantasy or both. 

The problem I see with "full range" speakers is the room. Do you have a full range room? I have played music with very accurate and tight bass in my sound room and the music sounds great. Put another song on that is fat and the whole room vibrates and sounds bad. 

Speakers do not have to be full range to make me happy. They have to be engaging and organic sounding, easy to drive with wonderful uplifting midrange. (don't get me started on "soaring hi's"
