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.

I’ve had Planar speakers since the early eighties and still have a pair of Acoustat Model X’s. The midrange and the High-end are fabulous! The low-end, while accurate, has no push to it.  If I play the beginning of DSOTM loud, the heart beat goes rattle rattle, rattle rattle, because it can’t produce the umph of a traditional speaker. I’ve made a bunch of subwoofers over the years and have an old Audio Research EC-2 crossover, but have never got it quite right. The ripple of the Mylar is so much faster than a moving cone!

All the best!
