Planars/ Electrostats benefits over box speakers?

I use to own a pair of Mirage M3's (Omnis)circa late 80's, that were very good at putting out a huge deep presentation, very detailed and dynamic with the McIntosh 300w/ch amp. I miss that sound, very wife un friendly though. I regretted the day I sold them. But O well, lesson learned! (don't let your wife make you sell your monoliths) Since then I have moved on to a conventional box speaker and I really like them as well :-) Maggies never grabbed me the way the M3's did, I will say.

"The sound is being squeezed through those drivers the same no matter what signal they are fed"

This IMO is not true. I have found that with proper electronics a conventional speaker can put out a huge (to the ceiling 8,10,12ft) presentation or soundstage. With the wrong electronics you will never hear this, the sound will be just barely above the speaker or worse down near the floor! So thanks, but keep your "door panels" and I'll stay married with my "square speakers". O and of the 40 or so speaker manufactures that produce 100k to 250k systems almost none (and except Martin Logan) use electrostats??? hmmmm.

Cerrot...." (and don't forget phase - can't believe how many systems are out of phase)".

I'm not sure what music you listen to, But for me PHASE is laughable. Because all the vinyl I listen too was recorded back in the 50's, 60's, 70's, 80's do you think everything was recorded in the same phase?? It wasn't, I assure you! Phase means nothing, I wouldn't lose any sleep over it that's for sure.
