Dual Gelcore™
The speaker cabinet is constructed in three
separate layers. The gaps between the layers
are completely lled under pressure with a
compliant form of non-setting gel. The two
constrained layers effectively damp the walls
of the speaker cabinet by converting higher
frequency vibrations into heat, which is then
dissipated harmlessly within the damping gel.
The graph (left) shows how the cabinet
performs in the mid-band frequency area from
500Hz to 2kHz. The blue line shows the amount
of unwanted sound energy produced by the
wall of a conventional loudspeaker cabinet.
Any erroneous boost or cut in level at this
frequency can affect the perception of musical
timbre and contribute to listener fatigue. You
can see from the trace of the red line how
the addition of Dual Gelcore™ technology
signicantly reduces the ability of the
speaker cabinet to interfere with the accurate
reproduction of the source material.
