absolute fidelity
and your foot will start to tap, and you will sway to the music. This is
basically what we term “PRAT” – or pace, rhythm and timing.
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,
simply turn the volume down on the remote control. Too little, and
the opposite will apply.
In general, the low-pass filter and the bass volume goes in opposite
directions. With higher bass volume, a lower frequency for the low-
pass is needed. And with lower bass volume, a higher frequency is
needed for the low-pass.
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 the rear wall or farther
from the rear wall,
the resonance may be reduced at the listener’s position. There
are no absolute rules concerning problematic rooms, so do not be
afraid to experiment with best woofer 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 and woofer volume. 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 more bass.
One trick that we have found to always work is NOT to have the
woofer towers placed symmetrically in the listening room. When
you have the woofers equidistant to the walls, there will be wall-
loading which will increase the volume of some frequencies in the
bass and mid-bass.
Place the left and right woofer towers equidistant from the midrange
towers. However, have one woofer tower further to the side of one
midrange tower, and have the other woofer tower further to the back
of the other midrange tower. It may look strange, but the principle
here is to position the midrange/tweeter towers for the best imaging
and soundstage, and the woofer towers for the smoothest and best
bass and ambience retrieval.
