Your reasoning is on the right track, but it's the wavelength specifically that's outside of the range for both Virgo and LIGO. As far as I understand the subject, we're running into physical limits for their detection using that kind of experiment. Instead, research is attempting to infer the mergers using pulsar Doppler shift measurements.
