Planars/ Electrostats benefits over box speakers?

A summary of planar characteristics vs. dynamic box speakers is contained in this Absolute Sound review of the Maggie 20.7s under the heading, "Design Advantages of a Large Dipole Loudspeaker." I think this is a pretty good description that addresses the OP's original question.

I found that his comments corroborate my own impressions of my 1.7s.

An agenda, other than sharing my thoughts on this hobby? wow...

on tunes, try buddy guy, done got old. You should hear his breath like he is hanging on your shoulder. You should feel the emotion coming over your shoulder lke a sledge hammer. My system is incrdedibly resolving. I had a pair of ohms back in 1982-84. Thy spent a year as front speakers, being relegatded to the rear channels shortly there after. Not a bad speaker but truly no where near the resolution of my stats.

Looks like your memory may not be working like it was just a few short weeks ago. I can refresh it for you if you like?

Cerrot ohms from early 80s would not likely do what you say. Those were the gen 1 models. I mentioned. The later revisions up to and including current x000 line are up to snuff in comparison to other very good modern speakers I hear.

I had those originals for years along with other more modern designs to compare including the newer ohms. I've a/b Ed them side by side so I am confident with my assertions accordingly.

At last weekend's T.H.E. Show in Irvine I took a good listen to the new Maggie .7, and to an ESL I hadn't before heard---a Sanders. I liked them both a lot, the Sanders a real lot. And a huge difference between a panel and a box speaker was reinforced by also listening to Vandersteen 7's and a couple of Wilsons at the show. As fine a loudspeaker as both companies make, the instruments and voices coming out of them sounded 1- Severely miniaturized, much smaller than in life and to the full size images coming from even the modestly-priced .7's. And 2- I found myself looking down on the performers, the sound of instruments and voices being about three feet off the floor. For me, that immediately destroys the "suspension of disbelief" a speaker needs to provide if I am to listen to music through it everyday. But that's just me!
