Largest Headphone Drivers?

[CT007]

So what phones are bigger than Audio-Technica's standard 53mm(2.08") drivers?

HE1000 = 65x100mm / OR 131.15mmx100mm((5.15" x 3.93")?
LCD-X = 106mm(4.17")
HiFiMAN Edition X V2 = 55x90mm(2.16"x3.54")
VOCE = 88mm(3.46").
Sony MDR-Z1R = 70mm(2.75")
HD800S = 56mm(2.2")

I dunno what Stax Lambas are. Maybe only measurable by surface area?

Why?

I'm doing my 18th grade science report on headphone drivers.

How big are HiFiMan HE1000 drivers?

I found... "131.15mm(5.15") X 100mm(3.93"), oblong". = Wow.
