Micro, not sure what technical literature you're seeking. I believe the readily published information is on the Stillpoints site, here. It's worth a read.
Apertures are patented, filed 2014, granted July 11, 2017. cf. here. From my understanding, changes in version 2 are not fundamental to the design. The panel is patented in such a way that its ebodiment can take many forms.
I met the inventor who came to my house and heard my system with Apertures in a trial position, different from where they are today. He is a well established acoustician who does work for a variety of large industrial applications, including NASA. Also from my understanding, most dealers carrying the Aperture let you take home several panel to try. They include 3M strips that allow temporary hanging on a wall and they are relatively light weight. Experimentation is easy. If you have access, I'd encourage you to try them if the need is there.
I have no interest in or association to Stillpoints. Out the various audio infrastructure components in my room (electric, acoustic, vibration), the Apertures are easily make the biggest positive contribution to the sound I get.
Hi again - I have swapped my Aperture 1s for IIs and am in a conundrum about how to configure them on my front wall. The attached picture shows the old configuration. I currently have 3 stacked in the middle only and am wondering if you have any guidance on where to try the next ones. Is the picture of your room here still representative of how you have them configured? Since my panel speakers radiate back as well as forward, Paul has given me stands to mount panels to put behind the panels. I guess I'll try that but am still confused as to what to try next.
