You are comparing THD to k2 and this at different frequencies!
For the other distortion data, Wilson is measured at 85dB/1m, 96dB/1m and 106dB/1m, the O500C was measured at 95dB/2m (review) and 100dB/2.1m (website) so a meaningful comparison is possible. The O500C were measured under anechoic conditions, where SPL decreases like in free field, i.e. 6 dB when distance doubles. Where were the Wilson measured? Anechoic or in Colloms' room, where SPL decreases 2-3 dB when distance doubles. If it is in Colloms's room, again, you can't compare because for the same SPL the loudspeaker has to work less hard.
If I look at the Wilson, the bass cabinet seems to be about half the total height, which would make a cabinet of 90x42x63 cm, whereas the O500C is 75x40x44 cm. The Wilson's side panel is about 1.7 times larger. Unless you measure the amount of acoustic radiation by the panels you can't know. The drivers in O500C are sealed at the rear, so bass frequencies have no effect.
>Nonsense Klaus, the ONLY clear advantage your speaker has is on-axis FR<
There are no off-axis measurements for the Wilson, so you don't know. Impulse response and waterfall are less good than for the O500C.
>I shudder to think how your system must sound<
You seem to be sure that a system selected on the basis of measurements alone must sound bad? Be assured, it sounds as it is supposed to sound, crystal clear, neutral, controlled.
