Using the remote control you can adjust the woofer's phase angle up
or down in five-degree increments. Depending on proximity to walls,
open spaces, cavities and cabinets, the gain, low-pass and phase of the
left and right woofer towers may be different.
The changes are subtle and they usually affect the imaging and
soundstage. Listen carefully to the positioning (in acoustic space), of
the orchestral players as you change the phase control. You may
notice small shifts in their apparent relationship to the other members
of the orchestra. Do not expect them to actually move. Expect minute
changes in the soundstage, the apparent width of the stage, your
ability to distinguish individual players etc.
Experiment with rock and blues recording (even if you only listen to
classical music). If the phase is correct, your foot will naturally tap in
time to the music. If the phase is out, you may think that the drummer
is having difficulty coordinating his cymbal work with his kick drum.
3.4 Further adjustments
With the woofer towers positioned in the recommended placement,
behind and outside the midrange tweeter panels, low bass in the
room should not be a problem. Should you have too much bass, turn
the bass volume down. Too little, and the opposite will apply.
In some problematic rooms a resonance may develop at one or two
frequencies that is unnatural to the music. By moving the woofer
towers closer to or farther from the wall, the resonance may be
reduced at the listener’s position. Also, staggering the woofers, with
one tower closer to the walls than the other tower, or closer to the
listening couch may quickly ameliorate the bass resonance.
In extreme cases, moving the entire system so that the listening
position is asymmetric in the room may solve the problem. There are
no absolute rules concerning problematic rooms, so do not be afraid to
experiment with your speaker placement.
Ultimately, it is all about balance. You have a number of controls at
hand with which to adjust the bass response, the low-pass filter
frequency, bass gain and phase. You can also move the speakers
closer together (for better coupling), and also move the woofer towers
closer together, or further apart, or even move them closer to a corner
of the room, for far more bass.
