Not that there's anything wrong with wearing comfortable shoes."You've conveniently moved the frequency where bass can be localized from 80 Hz down to 40 Hz. That's baloney. Find me one source that supports your 40 Hz localization threshold."

All tests I've ever read in the past 40 years using sine wave tones have shown that bass becomes directional above 40Hz.Those data are applicable to the audible effects from placing subwoofers to the side or rear of a two-channel audio listener.
They explain why side and rear subs are often heard/felt as separate sound sources with two-channel audio.
But real bass notes are not sine wave tones.
They have harmonics.
A Fender Jazz Bass note, for one example, will create more energy in the harmonics than in the fundamental bass tone.
That means quite a bit of bass energy will be coming from the two front satellite speakers in two-channel satellite speaker/subwoofer stereo ... and their upper bass output helps mask the location of nearby subwoofers.
When placed near the front speakers, subwoofers are usually sonically invisible up to about 80Hz. ... and that's why an 80Hz. 24db/octave crossover became the surround sound industry standard.
But that does not mean an 80Hz 24dB/octave crossover works to make subwoofers sonically invisible with two-channel audio when you place subwoofers FAR AWAY from the two main speakers ... such as near the side walls to the left and right sides of your listening chair ... or near the rear wall of the room.
