Do larger planar speakers produce more accurate sound?

The next room size is 16x20x8. Someone near me tried the Maggie bass panels. He sold them. They just didn't do the job.

@Corelli, what dynamic speakers are you using now?

Folks, my question is less about planar vs dynamic; it is more about large vs small planar.

I am not married to planar speakers, just to Clarity. What horn system do you like that can approach the clarity of planars?

What is Interference filtering?

@goofyfoot How do you like your ASR? Resolution? How often do you have to replace the batteries?

goofyfoot, what other amps have you compared it with for your Quad? If you like the Quad sound, you should try Sound Labs ESLs. They are incredible.

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?

@arion I apologize for the lack of clarity. By "accurate", I meant realism. Sor the sake of simplicity, let's focus on electrostatics.  To generate the same SPL with smaller radiating surface, it would mean greater excursion of the membrane than with larger radiating surface. I would think that the requirement of greater excursion would mean loss of tension (over many years) in the membrane and less resolution. Unless membranes require large excursion to produce higher resolution.

@larryi What is it about the low powered tube amps that you like so much?

Mofi also stopped carrying Quads for the foreseeable future.

Don't you find that horn speakers sound like a megaphone?
