Quad makes Electrostats, why now box speakers??

Quad has made electrostatic speakers for decades. So, why have they now launched a line of box speakers?? In particular, the model 22L which is an attractive 3 way speaker retailing for $1500 (I think) Anyone heard them or own them?? Do they sound better than the average floorstander, and is their bass, imaging and soundstaging better than the average British box speakers?? Need good input on this product "model"
