In pursuit of a goal that only a few will ever be able to reach: horn technology from bass to the high range! And the DUO MEZZO reaches it easily and implicitly, even a brief look at it will directly tell. The visual result is demonstrative, agreed. But the MEZZO’s sound stage and musical authority are equally so!
Transparency, dynamics, tonal balance, MUSICALITY and easy to drive.
The active horn subwoofer of the DUO MEZZO XD series is driven
by the XD-1000 power module. This integrated amplifier consists of
a 2 x 500-watt amplifier. Thus each of the two bass drivers is
powered by a separate amplifier providing for ample headroom
even in complex EQ settings.
The XD-1000 power module can be remotely switched on/off using
a 12V trigger signal.
Direct connection to integrated amps, power amplifiers or
receivers is done via speaker-level input terminals. Line level
inputs via XLR terminals are available alternatively.
The signal take–off is not only at high impedance, but is also
balanced and transformer coupled. This floats the circuit ground,
avoiding hum loops and easing connection to balanced and bridged
THE SUBWOOFER AMPLIFIER
The XD-1000 amplifier is equipped with an advanced digital sound
With a precision and bit accuracy unattainable using analog
technology, the digital crossover network eliminates all the passive
filter elements in the signal path of the subwoofer, thus circumventing a series of tonal problems caused by an analog filter technology (e.g. capacitors, resistors and coils in the signal path,
phase shifts and associated negative effects on the impulse
Volume settings, delay time, high pass & low pass filters and up to
10 parametric equalizers are programmable. Thus a variety of
parameters can be changed and fine-tuned by directly using the
control display at the rear of the XD-1000 module or by connecting
a PC or Mac computer.
This way it is possible to adjust the sound to individual preferences
and to allow for seamless integration of the system in different
