The problem with full-range are the very audible IM distortions and excessive beaming at higher frequencies.
Panel speakers also lack dynamic headroom (ie they don't go loud enough) and whizzer cones as used on many dynamic full-rangers are just crap and have very little to do with high fidelity.

We are both talking about large area full range stats where your first comment doesn't apply. As for the second, I don't suffer that issue with the Sound Lab design with its faceted panel approach. Are you familiar with the design?
Playing music with peaks in the mid 90s db range is all I desire. My ears stay the healthier for it as well.
I continue to marvel that the soundfield changes very little as I walk around my listening room - either in front of or behind the speakers. The notion of optimal seating position with respect to tweeter height is absent. Radiation at six inches above the floor as the same as six feet.
To each his own.
Similar experience to my Tannoy based speakers then but I expect my speakers to be capable of delivering peaks of 110dBspl or more as I listen in the mid 90s at times and to cover peaks cleanly I insist on 12dB headroom as an absolute minimum.
My ears seem to be fine. I can still hear my supertweeters which kick in above 15kHz which is far better than one would expect at my age.
As for panels in general I've listened to QUAD ESL 57&63 and decided that they are not for me.
Not least because my speakers inevitably find themselves with their backs on a wall so no OBs for me either.

Agreed. I've also heard stacked 57s and they didn't do it for me either. Unlike the U-1s, they cannot do 30 hz.
I gather you are not familiar with the unique SL panel approach. It uses a single diaphragm, but across a faceted grid in a curved arc. Mine radiate across 90 degrees.

I am fortunate having a dedicated listening room that allow the freedom to place them optimally. They're about eight feet out from back wall (pics in my gallery if you're interested).
Interesting speakers!
And yeah the advantage of living in North America which is largely empty compared to Europe is that space is cheap so I don't have the luxury of a large enough dedicated listening room.
He said dynamic headroom , ESL panels dont do soft , they do soft or loud , so they lack dynamic range, micro dynamics is essential to good dynamic range , unfortunately there are those who think loud is dynamics..
Agree with the advantages of a linesource , they have a big advantage over point source, due to the lower distortion from a larger surface area ...
Really? Whatever you say!
Read my post again ....
They also do in between. :)
micro dynamics is essential to good dynamic range
I certainly agree. What made the biggest difference in that regard with my system was replacing the preamp.
