Bo has simply discovered the weird directivity effects of ribbons. Nothing new about that. A ribbon tweeter is much too tall for the frequencies it is transmitting. This means you get weird flanger comb filter type effects - some frequencies totally cancel out while others reinforce. This is the 3D he has discovered. It is laughable really because this is an artifact. It isnt high fidelity at all. It really messes with the sound and your perception of where it is coming from as a function of frequency. Some frequencies will come from ceiling and some from only side walls and others from the speakers. Basically a total mess if you are a purist and seek high fidelity. But great if you like weird SFX and point sources to become larger than they should.
You also get weird artifacts with an Appolito design. He may have discovered this also. Nothing he has discovered has not been known for already 30 years. However he thinks he is on to something new because most speaker companies shun these type designs that give inconsistent 3D artifacts in favor of accuracy and high fidelity.
