Dunno, I'm ln the KEF site, and I think there are far uglier speakers than the Blades, different they certainly are but they're no more 'hideous' than say B&W's Nautilus, or KEF's own Q series for that matter.
I think they're refreshingly different from the normal boxes. I think they're slim and elegant, the only horrid things about them are the custom colours like Racing Red and Racing Blue.
They could be an H.R.Giger creation ...
I quite like the Blades, they look good in modern looking minimalist decors.
Although most peoples living rooms are better suited to regular box shaped speakers with wooden vaneers.
