I seriously doubt someone as knowledgeable and experienced as Mr. Vandersteen would make the numerous obviously false statements contained in your supposed quote of him you cited above in your last post.
Please verify this quote as valid by referencing your source for this quote. I’m almost certain you’ll be unable to do so, however, and you’ll likely just fail to ever provide any reference, never admitting to your deliberate false quote ...
It’s amazing how just how common the "all bass is monophonic" canard is and how reluctant some audiophiles are to reject it. After all, it can be resolved by listening, especially if you make your own recordings.
I’m not the one who posted Vandersteen’s observations, but Google shows this quote came from Vandersteen’s own website. (Scroll down towards the bottom of the page.)
There is a lot of research into sound and directional cues, including LF. It's puzzling how hard some will work to deny or ignore it.
