Background knowledge
The ICS80 Stereo speaker com-
bines two 2-way speakers in one
housing and as such, it is a true
stereo speaker.
How is this possible?
The ICS80 Stereo uses the
frequency-dependant emission
characteristic of dynamic
speakers.
The higher the emitted frequency,
the stronger a speaker bundles.
An additional plus point to this
characteristic is that the human
ear can positionalise treble fre-
quencies but not bass frequencies.
As a result, the positionalisation
and therefore the spatial represen-
tation of music is significantly more
influenced by the treble frequencies
or respectively the tweeter.
The ICS80 Stereo has two com-
pletely separated tweeters with
axes that are offset by 37°, which
means that they emit in different
directions, thereby creating a
stereo image.
In the bass range, the right and left
channels are coupled electro-mag-
netically through a double voice
coil to a joint bass membrane. Both
coils work electrically separated
from each other but the generated
magnetic field creates the effect of
a combined drive unit.
In terms of the efficiency factor, the
two tweeters and the double voice
coil bass are perfectly matched to
each other and, as if by magic,
create the illusion of true stereo
from just one speaker. This im-
pression can be further strength-
ened by the reflection of sound
waves from nearby walls.
Which amplifiers are suitable?
Through its galvanic separation,
the ICS80 Stereo is well suited for
all types of amplifier because, from
an electrical point of view, each
amplifier will find two, separate and
individual speakers connected.
