SUBV10 & 12 Manual
subwoofer by ear, listening for the smoothest bass that is devoid of any significant
peaks or valleys in its overall response—i.e., without too much or too little bass at
certain frequencies.
Note:
This control is bypassed when using the LFE input on your subwoofer.
The switch in between the knobs, labeled PHASE, adjusts the phase of the
subwoofer’s output waveform in relation to your main speakers. When the
subwoofer’s PHASE switch is in the 0 position, the cone will have a forward
excursion in tandem with the sound signal (i.e., it will push out with the positive
half of the sound wave); when the switch is in the 180 position, the woofer cone
will have a reverse excursion in the opposite direction of the signal (it will move
inward). Depending on your room and speaker placement, one switch position
may be preferable.
The preferred switch position can depend on a variety of factors, such as your
subwoofer’s proximity to your front speakers, where it is located in your listening
area, etc. Try flipping the PHASE switch while listening to music with obvious and
consistent bass content. Determine which position yields the most bass. If this
setting results in too much bass, adjust the LEVEL control. It is best to evaluate
this while sitting in your main listening position while someone else is flipping the
switch. Leave the switch in the position that sounds best.
