Electrostatic pros and cons.

I recently saw a feature on the program, "how it's made" on electrostatic speakers and it piqued my interest in them. I was wondering the pros and cons of them, their placement, space needs, sound, etc. Any advice would be appreciated.

Electrostatics are very fast and transparent. Can any woofer match ?
This is all BS, you need big panels and right amp, no hybridization please.
Bill, time to replace your horns/not horns with something like JM Labs Grand Utopia.

Yes but my experience is with a bi-amp set up and woofer array. I think the Sander’s Sound speakers are a great example of a hybrid speaker. The Martin Logan speakers I have heard, not so much.
"Mr Salami" classic response!! That induced a nice laugh here!
Kudos to Duke (and his speakers)

@bdp24 - I don't want to mess with woofers on the Quads at this point. (There's a Rythmik 12" with a paper cone in that room for the theatre system-it's where we watch movies-altogether separate system). 
I have a pair of 15" Rythmiks running with the Avantgardes, and they are pretty dialed in. I'm good. ":)
@inna- I am at a loss for words. Say Wut?
