As for other Tektons I've mentioned earlier, If you really want, I could find the measurements done by 3rd party, but not specifically your model, but I think you've missed that part, I guess due to lack of basic english reading comprehension.
I've been doing this long enough to create at the least somewhat educated opinion based on such graphs.
Your current speakers very unusual twitter array is more than likely to create diffractions and there's near zero chance someone actually modeled this, likely to be designed by ear.
I really feel compelled to mention one detail about iFi audio, company I've never heard before today and my opinion is on zero knowledge of the company, HOWEVER I've noticed this little piece of design on their site.
That "turbo" font, slant and overall design looks mighty familiar. I wonder where did I see it... hmmm...
Maybe here:?
p.s: About this part:
I'm calling a BS police. I doubt you've done anything except Auto-Room correction. You surely didn't mention any DSP in your audio path, except Denon avr.
