Haha thats amazingly confusing when you look closely.
I'm using baby pin reciever plates on 4080 extrusion with m6 thumbscrews into drop in t nuts. There is only one c stand. The extrusion is actually two parts in a cross. The speakers are on the horizontal extrusion mounted on magic arms. My momitors are angled slightly upward and the bottom is a few inches lower than standard desk height.
