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.

@Corelli, what dynamic speakers are you using now?

The KLH Nines (which apparently nobody here has owned/heard) have excellent dynamic range and bass impact - even when used in single pair configuration! They were designed by Roger West (Soundlab) and Arthur Janszen back in the early Sixties. The Nines beat the Quads in the above performance areas due to larger surface area and power handling. Janszen sells restored pairs at very reasonable prices.

I can speak from experience, having a pair of KLH Nines in use since 1992. I used a variety of amps with them, including Bedini 25/25's and Futterman OTL's. With the power amp section of the Carver Receiver (125wpc) they had floor-shaking bass power!

I sure like Quads, I went from Quads to small planars 25 years ago. I was a big fan of Infinity's IRS Beta. I had them for 20 years or so. A guy that logs on AG fixed them for me. He is a VMPS guy, so I tried them. WOW for the money. Small planars and ribbons are the best for speed. Some are push only drivers, some are push pull. They show every flaw in my humble setup. WCF bass drivers. 19hz to 26khz so the specs say. They sure make my wife yell, MORE..

All things being equal, yes.
