For sure.... Nobody reinvent the wheel.... But the japanese article is very clear...
I dont pretend to anything myself except being the father of this maxim:
Dont upgrade embed everything right before....

By the way i enjoy precise very good bass i hear with my stomach from a 7 inches driver in a square small room 13feet by 13 feet with bad location for one speaker in a corner, thanks to Helmoltz activation method of the room....Passive materials treatment is half of the story to tell....
Just a remark about the direct sound....
Even in near listening reoom treatment and controls work in a huge way because of that... When someone speak of direct sound it is a "physical concept" about the wave coming from the source, but acoustically for the ears there is NO solely direct sound perception in a closede small room, the ears recreated the sound perception in milliseconds with the physical direct sound and the early and late reflections.... Here we must distinguish physical concepts and neurological acoustical one.... The sound we hear IN A SMALL ROOM is never the direct sound....It is a composite of the different multiple waves summed into one interpretation by the brain.... Many people missing these distinction affirm that near listening can spare someone of room treatment because of these confusions... The most astonishing fact in audio for me was meditating about the fact that the sound waves cross my room 80 times per second....Then what i listen to is this composite sums of waves i interpret like music in my room....
For sure for the brain the difference between what is a direct sound, and early or late reflections are linked to timing and distance in the room and the location of the listener.... It is relative....The brain recreate the sound when i move in my room with these 3 psysical concepts but what i listen to is a COMPOSITE always of these three....
i can for sure glued my ears to some inches of the driver to hear ONLY the direct sound but i am not sure that these noise will be interpretable by the name music....But even in a headphone my brain created the musical sound with the direct physical waves of the source with the early and reflected waves of the shell room...No headphones sound the same in great part because of the shell room vibrations and reflective properties...

Just a remark about the direct sound....
Image focus comes almost entirely from the direct sound.There is no direct sound separated from reflected sound, early and late reflections for the brain...The brain work with the three , direct, early and late at the same times in milliseconds to recreate the image and timbre experience....
