Are these Speakers the BEST on Planet Earth ?...

...You'd better watch John Darko's YouTube review of the KII3's, and then do yourself a favor and watch designer Bruno Potseyez YouTube clip, where he explains the technology he employed in the KII'3. They are nothing short of amazing, in every possible way.
