Near field listening is generally spent with smaller speakers ...
I redesigned the porthole of my small speakers to go 50 hertz and when room acoustic is well done all is good at least for me ... Then it is not nearfield listening that matter but always acoustics , a box speaker is a resonator waiting to be tuned as much as any room wait to be tuned ... ......
But even with good room acoustic a small speakers set will not go 20 hertz clean for that we need a grid of subwoofers or at least one well coupled and this is costlier 😊... I dont need that anyway ...music shine for me ... My dream is very good S.Q. for peanuts ...
The only thing i need i hope this year , is what you have : the BACCH filters for my top headphone ...
Near field matters but it isn’t an all or nothing proposition. It has pretty much no effect on bass
