What are the advantages of electrostatic versus floor speakers w/wo external drivers?

Different, yes, better?

I love BIG speakers.  I've heard a lot of Maggies, and Apogees. I like small planars too. I like any alternative to a round speaker, above, 300 hz.

Round speakers, domes included, carry a lot of mass. Just not as fast as most planars.. BUT all speaker drivers, have their issues. 

Like huge panels, are prone to bass distortion, they collect it, So you have to control it or deal with it. Usually lose it, dampen it,  or servo control it. Servo is the best, for my application..

Hey Sokogear,

I've been a fan of line sources and ESL's for many years.  What they do most of all is interact with the room very differently than a box speaker. The narrow dispersion causes more of a headphone effect at the listening location.  They also are great at sounding the same no matter how high up you sit.

They can be much more demanding of an amp, and require more space behind them, and also have a narrow sweet spot, along with a non-neutral presentation.  However, some fans can't imagine listening to anything else. 
After a lot of listening, and reading, I don't find the argument that they are faster as compelling as the argument that they just interact with the room differently and sometimes very very conveniently.

Best,

E

I like to be able to be in different locations since my system is in my den that is open all the way back to my kitchen seating area - probably a total of 44' x 18' with some openings in the back.
