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. However, for proper soundstage
development, the midrange/tweeter wings should be symmetric in
the room.
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.
The Refinement stage
After following the rough setup guide above, you may not be
completely satisfied with the results. We share with you here some
of our observations in setting up these loudspeakers.
Make One Change At A Time
One rule of thumb you should always keep in mind. Make one
change at a time! Do not, for instance, change position of the
speakers and make an adjustment to the amplifier all at once.
Make each of these changes separately and note the difference -
by listening - with each adjustment, then make the next change.
Each adjustment, in positioning, and in control adjustment will
result in a subtle sonic change. Even when you are moving the
midrange/tweeter panels further apart, or closer together, move
