The variant 112A can reproduce frequencies
down to 63Hz , so in those applications where no
high sound pressure level is required (speech,
vocals, etc) and there is no need of extending the
low frequency range the system can be installed
without subwoofers. If it is required extending the
low end then the variant 18A is recommended.
It is also recommended when combining
systems to use two different signal lines and one
external DSP to align both systems.
In applications like live sound concerts, disco
dance music, where high sound pressure level is
required double eighteen subwoofers should be
used. DAS Audio recommends the LX-218CA. To
align both systems and external DSP and two
different line signals will be needed.
Note: the relationship between the number of
subwoofers and the number of variant 112A
depends on the application and is a parameter to
be defined by the user.
When using a subwoofer other than the variant
18A in combination with the variant 25A units, it is
recommended that external processor be used to
filter the signal fed into the variant 25A units at 138
Hz.
If an externally amplified subwoofer unit is to be
used in combination with variant 25A satellites, the
signal treatment will depend on the characteristics
of the subwoofer used. In order to achieve a good
quality sound, DAS Audio recommends the use of
variant 18A subwoofers.
