Cabinets
All D 4 cabinets are made of heavy MDF board, a solid and resonance dead base for the
drivers to work in.
However, the most remarkable cabinet feature is probably the
Double Curved front baffle.
It is common knowledge that one of the most rigid constructions
at all is a round shape; a ball, an egg etc.
Therefore the front baffle of D 4 has been “cut out” from a giant
ball and thus the name “Double Curved” front baffle. It consists
of a shell, moulded from foamed ABS plastic, mounted on an
MDF board – with resonance damping foam in between. All
materials are characterized by excellent acoustic properties i.e.
high internal damping. This prevents vibrations from “travelling”
from one driver to another.
Also, the planar design gives optimum working conditions, i.e. a
minimum of diffractions, for the asymmetrical placed tweeter. By choosing the
asymmetrical design, no distances from cabinet top and sides to the tweeter are identical
and thus edge reflections do not accumulate. The result is a crystal clear treble
reproduction – which is essential in order to benefit from the extended treble contents of
the new multi channel sound formats.
The finish of the D 4 is a light anthracite lacquered front baffle combined with black ash,
light – or dark apple wood finished cabinet sides.
