SUBV10 & 12 Manual
Underneath your subwoofer’s cloth grille are two round knobs and one toggle
switch. The first knob, labeled “LEVEL”, adjusts the subwoofer’s volume. If the
component sending signal to your subwoofer has its own bass management
features, this knob can be set somewhere in the middle of its range so that the
subwoofer’s output level is controlled by your surround receiver, amplifier, or
processor.
Subwoofer Level Control
The second knob, labeled “CROSSOVER,” sets the subwoofer’s internal crossover
frequency, which is adjustable between 40Hz and 160Hz. This frequency setting
determines the upper limit of the subwoofer’s usable bass output; thus, for an
80Hz setting, the subwoofer’s operating range extends from this frequency down
to its usable low frequency limit.
Properly setting the crossover ideally results in a smooth transition from the low-
frequency limit of your main speakers to the upper limit set by your subwoofer’s
crossover control. Usually, this can be achieved by setting the knob to the – 3dB,
low frequency roll-off response specified for your main speakers (check your main
speakers’ manual for this specification).
FOR EXAMPLE: If your main speakers have a frequency response rating of “80Hz –
20kHz, +/-3dB,” the -3dB, low frequency roll-off point would be 80Hz. Therefore,
set your subwoofer’s crossover frequency to 80Hz as a starting point. You may
wish to further fine-tune the bass blend between your main speakers and your
