Axiom Home Page Forums General Discussion Home Theater Localized Sub

AFAIK this whole "can't localize below 80 hz" is like the "you can't see your screen flicker above 56 hz". It's a generalization, everyone is a bit different.

For low notes you're normally OK because the harmonics go through your regular speakers and the ear + processing in the brain take localization cues from the harmonics preferentially over the low notes so sounds seem to come from the regular speakers.

I am very far from an expert on this, but my first thought would be to take the subwoofer level down a tiny bit and see if that helps. It's been ~25 years since I studied this stuff but I believe there's a threshold effect here -- if the hf signal is over some threshold relative to the lower notes then your brain "votes the low notes off the island" when it comes to figuring out where the sound is coming from.
