Why price of Tannoy speakers from online retailers in UK is cheaper than in US


I am looking for a pair of new Tannoy Kensington GR speakers. I notice the price from many online retailers in UK is cheaper than in US.  I believe they are authorized dealers because their websites are listed on Tannoy website.  Current price in UK for a pair of Tannoy Kensington GR Speakers is 9290 pounds(approximately 12K USD). Price in US is 9K/each or 18K/pair.   If we add shipping fee and import taxes and duties, it is still significantly less than the price in US. does anyone have  experience with buying Tannoy speakers directly from UK retailers.  Your input is appreciated.

Thanks everyone for your input.  Just like the previous user suggested, I need to be patient.  I am in no hurry to buy and will wait for a couple months. If there is no good deal on the horizon for either new or used Tannoy speakers, I may either check overseas or entertain other brands.  

has anyone listened to the GRF 90?  Just wonder how it's compared to the Kensington and Canterbury.  
I tried to buy a little thing from a manufacturer in England. They wanted me to pay the VAT crap. Told the guy in an email I wasn't going to support their socialist society. No f***ing way. He
