For all the praise B & w is getting in this thread some people are forgetting the main thing,no matter how great the design is a speaker has to sound good,graphs & charts mean squat when it comes to personal taste in the way a speaker sounds.
Im not a fanboy of Wilson but im even less a fan of the B & W sound,great company,great customer service,great craftsmanship,great specs & response =terrible sound to my ears,just goes to show that good sound is subjective not spelled out on paper.
