I wonder if they are really special glass. Someone recently posted thing about how glass isn't actually as bad for sound as you might think. Now make it very thick glass and realize it'll change the whole game.
Peter from AVshowrooms really likes the Cube setup.
The reaction to these different glass speakers is amusing in the
reviews on Amazon. They are unlike the Perfect 8 however, as they're sealed and the only sealed ones in the Perfect 8 lineup seem to be bipoles.
To me I can't help but wonder if glass is quiet that expensive. I mean compare to all the employees needed to add all the layers of other speakers together, do the painting and finishing etc...
