I wish I could give you double reputation for your post.
You obviously have a vast and much larger repertoire than me about this subject and I appreciate your patience and your willingness to share your experience.
You are right. There is no way to achieve xtc or beamforming without DSP.
What I wanted to say is that such DSP may not be loaded with a custom measured personal room binaural impulse response (PRIR) to make that HRTF translation in digital domain, so that such part of that HRTF translation may naturally occur in the acoustic domain because the listeners hears through loudspeakers.
AFAIK, the custom bacch-sp also acquires what I would call a PRIR and uses head tracking to allow the listener to turn his/her head.
Perhaps I am reading this page and his FAQ too optimistically.
Throughout those pages, although comparing the BA2L method to ambisonics and expressly using the phrase "3d sound", he carefully does not mention the word "elevation" neither "error in elevation" or "elevation perception collapse".
That's the main reason I keep asking if someone compared the number of elevation errors listeners have with bacch-sp versus ambisonics with an exponential increase of my post count...

Care to tell us how you plan to do any sort of HRTF, crosstalk cancellation or beamforming without a DSP?

No, not in a room with two speakers at 10 degrees. The PRIR the Realizers develops is translated to headphones. If you turn your head wearing headphones the processor can track your head turn and rotate the image to track it. It works because the relationship of the transducers to your ears is still fixed. You're not going to do that with two speakers in front of you.
AFAIK, the custom bacch-sp also acquires what I would call a PRIR and uses head tracking to allow the listener to turn his/her head.
I'm skeptical that he's actually saying that, and that it could be done with speakers. Pretty tall order. Link to the paper perhaps?
