The cut-o frequency for the low frequency eect (LFE) channel can be selected
separately as 85 Hz or 120 Hz. In certain subwoofers, the LFE content above
85 Hz may be redirected to the centre monitor, allowing full range LFE channel
monitoring.
Typical recommended distances from the wall behind monitors and subwoofer are
shown in the picture overleaf.
Placing a subwoofer at a wall or in a corner produces the highest low frequency
output. At low frequencies, the attest response can be achieved when the room
mode resonances are equally excited. A single subwoofer is usually placed along
the front wall, slightly o-centre from the room’s middle axis. Two subwoofers
may be a good solution to produce and even atter response. Note that during
level calibration, the subwoofer output level is set at the same level than the main
monitor system.
Genelec active 7000 series subwoofers have a crossover lter set to 85 Hz. The
subwoofer reproduces the frequencies lower than 85 Hz. Higher frequencies are
reproduced by the monitors.
Genelec Smart Active Monitoring (SAM) subwoofers enable selection of the
crossover frequency between 50 and 100 Hz. Set the subwoofer crossover to a
frequency where both the monitors and the subwoofer output sound.
Adjust the subwoofer phase at the crossover. Reduction of sound level may occur
at the crossover frequency if the phase is not aligned. The phase alignment is
described in the subwoofer operating manual.
