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.

@helomech: If you want to hear a Maggie with midbass punch, try to find a pair of the 3-panel Tympani models. Harry Pearson mated the two bass panels from a Tympani with the m/t panels from the Infinity IRS to create his own "super speaker".

The best midbass I've ever heard was that produced by my pair of Tympani T-IVa. But the Tympani bass panels need:

1- To be braced. Mye makes a stand for the Tympani. One guy on the Planar Speaker Asylum runs a plank of wood from his Tympani panels to the wall behind them!

2- To be placed at least 5' from the wall behind them. However, they may be placed right up against the side walls, which has the added benefit of eliminating the front-to-back dipole cancellation on the sides of the panels against the walls. Free bass!

3- A LOT of power, the more the better. 

A note to planar lovers, whether of the magnetic-planar variety (Magnepan, Eminent Technology), ESL, or ribbon: The Tympani bass panel is a GREAT sub for your speaker.
