" The floor standing range comprises slim elegant enclosures featuring resonant side panels which radiate sound in a radial pattern, not just to the front as in conventional designs."

Perhaps Troels wanted to emulate controlled resonances like this manufacturer...
The concept goes against everything "established", I would like to hear them, but I am very far from Austria....... 😉 Has anyone here done it?
And yes, here we go again.....
Diminishing returns...
If I increase the box from 5kg to 10kg, I get a 6dB change. 10kg to 40kg: 12dB change. And it's just benign dipole radiation. It's not like the box flexes from profound kPa changes imposed by the paper cone.
So the vibrating box argument is not entirely convincing on its own. That said, an offset woofer can probably make the box rotate on a micro level, which would be bad for coil centring. Presumably that would add distortion, even if the box itself doesn't seem to rattle against any hard surfaces.
