SYSTEM ALIGNMENT
The system S26 / S10 / S12 + S12W is pre-aligned from the factory. Do
not forget to add the geometric delay depending on the configuration
used.
1.3.2. General purpose (Standard) presets
These presets can be used to match the S12W with any other cabinet. These
presets are not prealigned, so a time alignment with the top model satellite is
recommended. There are three standard presets, and they are defined by the High
Pass Filter frequency, which can be selected at 80, 90 or 100 Hz:
LPF80 Standard
LPF90 Standard
LPF100 Standard
1.3.3. Cardioid presets
The S12W enables the combination of three or multiple of three subwoofer cabinets
in an array to provide exceptional directivity at low frequencies. High directivity at
low frequencies has two main effects on the sound field: firstly, the low frequency
level behind the subwoofer cabinets is greatly reduced; secondly, in closed venues
the diffuse sound field at low frequencies is reduced so the
low frequency reproduction is much more precise. The
typical operating range of a traditional subwoofer tends to
be like a monopole, i.e. tends to radiate with the same
energy in all directions. This behaviour implies that the
control of radiation at low frequencies is very difficult
because the wavelengths are very large compared to the
size of the source (8.5 m at 40 Hz).
