    TD Silent with Speed Controller less than 20db?

    Has anyone heard of the TD Silent range inline fans? Their 8" model has 3 levels : 90/92/102 W at these noise levels : 21/24/28 DB You can also get a speed controller for it by SP, meaning you could make it even more quiet, below 20DB - thats insane Has anyone used one...
