That statement is absolutely untrue and I can't believe you said that. For the most part with speakers, form follows function and so it is with Wilson. The size, shape, and material used in their construction has everything to do with their performance.
Seriously? You don't think an inexpensive cabinet could be built with the rigidity and acoustical properties but without the metro modern furniture/Ferrari look and feel? You think any other single component in one of their speakers costs as much as that cabinetry? What component would that be? One of the drivers? I'm not saying that cabinet design doesn't impact sound. Of course it does. And I'm not saying that Wilsons aren't very fine speakers, they are. What I am saying is the high end has a ton of money tied up in the way it looks, the impression it makes before it is ever powered up. Any denying that is pretty deep denial indeed.
