(Edit): Do not take my comments as a criticism of Dr. Floyd Toole. He is a knowledgeable professional.
Same could actually also be said about money, food, health, exercise, sex, happiness... etc. As Toole also pointed out - we as humans are often fickle
I tried many times to teach others about things that I new - and believe me, it went the other way too Some are just better teachers than others and have better voices and choices of words.
Try and read some of the threads where Geddes tries to explain about multiple subs and acoustics. Here you will see that people are still fighting to grasp many basic principles.

Default Blumlein style array?

But when superimposing closed box speakers, all information in the recording is presented to the carrier medium and listener directly.

I've succesfully put my idea to practice.
The speakers form a superimposed Blumlein style array.
Simple to try. You need an amp, 4 speakers and a stereo source.
Try it. Why not.
Can you elaborate more on how you superimpose your 4 speakers in a Blumlein style array? Maybe some pictures? I've got 4 identical speakers and an amp to run them all ready to try it.
