The math says, if implemented correctly, WFS is better than sitting in the sweetspot of any speakers. Also, there's no sweet spot with this technology.
It would force compromise on every other aspect of the product.
In the real world = more time (at every stage of the R&D and manufacturing process) + extra material costs (more tooling, more PCBA's, more screws, etc.).
I personally think that this issue will become a very big deal over the next decade or so, but at this point the market isn't applying enough pressure for the big companies to change their GtM processes.
There's a huge runway in front of us for both products and technology.
'Acoustic Holography' has worked for some time, commercial implementations have been few and far between, mostly because what's in the market is already selling boatloads without it.
It'll come eventually, there are a few groups dedicated to it.
A successful anchor in that space will allow companies to go deeper into applications.
