this is one of those situations where both can be true.
depends on the setup.
i think what was said above is, the subwoofer's reverb is reflecting off of a surface louder than what can be heard directly from the speaker cone.
i've done this myself with creative's reverb.
the front speakers output was louder off of the rear wall than from the speakers actually in front of me.
when such an instance is true and right there in front of you, the only chance of finding the source is to listen for the mechanical noise of the cone moving in and out.
not always a noise that exists, and even when it does exist.. the noise can be manipulated (or anchored) away by reflections.
if the mechanical noise accumulates in a corner stronger than from the cone, its a dumb guess.
you'd say to yourself 'do i pick the loud location or the soft location?'
either one is hope and could be wrong.
however, longer seperation between reflection and source can change things.
the mechanical noise could be clearer to reveal the source.. or the source could be dirty, and the accumulated reflection sounds cleaner.
i'd say its a bar joke highly dependent on design and instance.
without using the reflections to your advantage, its quite easy to tell where the source is.
sometimes you stand in a position of the room and the sound is equal from all directions, no point trying.
but walking in some direction could reveal amplitude or time domain.
i'd say there are more setups that reveal the source, compared to systems that have made an effort to hide the source.
