Do larger planar speakers produce more accurate sound?


Planar speakers generate sound pressure via vibrating membrane panels. The excursion of the membrane x radiating area= sound pressure. This would mean that for a given sound level, membranes have smaller excursion in larger planar speakers than in smaller ones. Does this mean that larger speakers will produce more accurate sound?

I am not talking about the obvious benefits of the larger speakers in terms of low frequency production, so let's not get into that.

The smaller planar diaphragm has less mass to contend with. Also, since planars behave as an imperfect line-source in practicality, the larger panel will have a  greater total of interference filtering. I haven’t compared measurements of say, the Magnepan LRS and 1.7i, but I would bet the former gets a little closer to textbook ideals. However, the average listener will probably perceive the larger of two panels to sound more life-like, all else being equal. 

what @jjss49 said!

FWIW, I own Soundlabs and previously owned Quads, heard a million Maggies in many systems. 

Small planar = no bass. That's why so many have tried cone woofer hybrids, 

I own M545 Sound Labs and with Bass focus, it has plenty of bass. I am not a bass freak and I don't listen to rock. I am thinking about moving to a bigger room. The question is Quad 2912 or bigger Sound Lab?
