Help . . . I’m dumber than my active speakers!

Well you have a pretty killer system it just may sound better than those Dutch & Dutch 8C's. That said definitely experiment with positioning.

The D&Ds have built-in room correction and can be setup all the way against the back wall.  They also have a deal with Bache to give you the surround sound effect. They take a while to set up. I had them done by an expert who did it right but still took 2 hours. On your own you are likely f-ed. Pay a trained D&D man.

They do sound amazing in the low and mid. I preferred by Fritz BE's on the highs.

Bite the bullet and move on to somethin’ else. It sounds like that speaker is not your cup of tea and never will be!!

It is strange that in your room the Yvettes outperform the D&Ds. Definitely try what @erik_squires suggests aboveand also try feeding them the same signal that goes into the parasounds.

Try near listening yes but before put some enough big damping weight, concrete in my case , on them...Tune the weight necessary by listening experiment...

And isolate them by some coupling-decoupling sandwich of materials ( granite plate -quartz feet -granite -sorbothane duro 70 plate- bamboo plate-cork plate-oak plate ).
