"the Rhythm2's single 18" woofer offers 50% more area (254 in2) than do the f212v2's two 12" drivers (168 in2)"

Not sure if I'm missing something but the area of 2 12" circles is 226 in^2 so a single 18" would only have 12.5% more area.

also "This generated a flat room-response curve: ±3dB, 8Hz–2kHz (fig.1)
Really? that's not what I see in figure 1.
