Since low frequency waves have a very long period, I don't think any mics near each other would give much useful location info. Depending on where a given mic was relative to the wave, I expect the recorded volume would be very different.

And yes, I don't expect comparing amplitude to be useful--sound localization almost always uses TDOA/phase difference for that reason.
