SOUND RADIATION
Just as important as a correct amplitude and phase in the frequency
characteristic is an exact sound radiation, where the acoustic energy is radiated
uniformly across the complete frequency range. The new principle of directing
the sound of the tweeter, guarantees a
planar wave at the sound opening. The
built-on wave-guide then bundles the
radiated sound in exactly the same way
as the midrange/bass speaker does in its
transition band to the tweeter, guaranteeing
a constant radiation behaviour at the
crossover frequency. The driver of this
tweeter, which is capable of high sound
pressure, works with a membrane in ring
form. Opposed to normal dome speakers,
usually found in hifi and studio systems,
this enables the tweeter a distortion free reproduction of impulse peaks even at
very high volumes. The result of the correct digital equalization is neither
corrupted nor nullified by the drivers’ components. In case of a complete overload
of the input signal, utilization of a limiter in each path protects the components
from destruction.

THE 3 RD WAY
A special feature of a two-way loudspeaker is the three-way processing of the
signal. In addition to the two-ways which are fed to the drivers via the built in
amplifiers, the DSP of the ADM20 calculates a third way in order to reproduce
the bass range. This extends the bass range to the lower frequency limit of 25
Hz. This bass signal can be accessed at the analogue output socket and be
connected directly to the ADMW. If the ADM20 “WooferMode” in the parameter
menu is turned to ON, then this output will be switched from “bypass” to “ADM
equalization”. Thereby, all frequencies under 100Hz are redirected to the ADMW
which naturally contributes to relieving the 8” drivers. Therefore, the combination
of the ADM20 and ADMW not only reaches the lowest frequencies but can
significantly increase the volume of higher frequencies. Spitzenabhörlautstärke.
The signal at the analogue output socket can naturally also be adjusted from the
remote control.
