Stereo Subwoofer Pairing

Deep bass is not directional, and that has been shown by a lot of research. Yet, as some have argued here, it may sound as if these deep bass notes do indeed emanate from different speakers. The explanation is that the human brain uses the upper harmonics from the main speakers to locate the deep bass tones.

It is absolutely true that harmonics can suggest that the bass you’re hearing is directional and often, when bass sounds directional, that’s the explanation. But it is not absolutely true that all bass is non-directional; differing phase between bass signals can create the impression of direction. That might be obvious if you really think about it, but it’s also been proven through research, including in work done on multichannel audio by Microsoft.

Where’d you get the idea that stereo subs would be a good idea? Or even discernable.

Use of multiple subs can minimize rooms nodes so, depending on the room, it can be an excellent solution to achieving flat in-room low frequency response.

... stereo deep bass is a myth ...

Not exactly. Depending on the phase of the LF signals, it is absolutely possible to hear bass in stereo.
