@thespeakerdude Thank you for that great DPA article about surround sound formats, DPA is also one of the very best microphone companies anywhere. This article and the YouTube video with it highlights the futility of microphone stacks of any type.
So we have to put on headphones every time we watch a movie, we could incorporate 3D and speakers in a standard headphone / glasses setup, Or we use our phones to set up a grid around our head that would allow lasers can send sound right in your ears, phones already grid your face, no problem. Next problem.
