since we have 2 ears would it be best to use a dual opposed sub at ear level assuming you have a really wide head ?
and during the crawling what should you be listening for and what should be playing over the subwoofer ?
Unless your ears are 10 feet apart, arrival time differences are not going to make a difference to what you hear at subwoofer frequencies.
A person could indeed always experiment. Theoretically, at typical sub frequencies, the sub's radiation pattern is close enough to omnidirectional as to not much matter during the crawl, as I understand it. Put it however you can.
Frequent participant Ricci has interesting experiences with subwoofer orientation for measurement purposes with multidriver subs. The differences between mic on the no-speaker side and mic in front of one of the drivers are smaller than "seems" like they should be, but more than zero, so at least at his mic distances, radiation is not perfectly omnidirectional. Of course the fact that the sub is on the ground during testing prevents perfect omnidirectionality, and may even explain some of the difference somehow.
