[. . . ] The speaker driver used in the loudspeakers will change their characteristics subtly over the first two weeks of use as the suspension of the cones will loosen up slightly, producing a trace more warmth to the overall sound texture.

For optimum acoustic performance, we recommend that you place your speakers at least 6-8" from rear walls to reduce unwanted reflections that can muddy your sound. [. . . ]
