Is there any way to know if macOS is doing something like this natively already? I ask because my late 2019 16 in. MPB has ridiculously amazing speakers for its size and format. I’ve always wondered if it was more than just the hardware.

I don't know what the Macbook does, but I do know that simply equalizing even a cheap speaker to match a target response curve produces astonishing results. I once used $$$$ audio hardware with many parametric filters to calibrate the tinny, resonating built-in speakers in an old LCD monitor. It sounded fantastic.

  Yes. Apple has added cross-talk cancelation to their macOS devices; albeit, not as wide or flat as ours. See here: http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=/netahtml/PTO/search-bool.html&r=1&f=G&l=50&co1=AND&d=PTXT&s1=10524080&OS=10524080&RS=10524080 http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=H.... Funny, we chatted with them ~1 year before they filed...

    Fascinating. Thank you for doing the leg work here! I never would've thought to check patents.

      Also, unlike with LCC, Apple's implementation does not route through the output. So, you cannot correct for crosstalk with it to external speaker units.
