than 14” from a room boundary will diminish the sonic results of your listening. Sitting
directly in the center of the room will noticeably reduce the perception of low frequen-
cies.
Decide where you want your favorite listening position to be. Please remember
that Alexia will fill almost any room with the most beautiful sound available. Because
the propagation delay is adjustable on the Alexia, if you take care in placing your new
speakers, you will optimize Alexia’s performance in your room.
Speaker Orientation
Speaker placement and orientation are two of the most important considerations
in obtaining superior sound. The first thing you need to do is eliminate the sidewalls as
a sonic influence in your system. Speakers placed too close to the sidewalls will suffer
from a strong primary reflection. This can cause out-of-phase cancellations, or comb
filtering, which will cancel some frequencies and change the tonal balance of the mu-
sic. The Wilson Audio Setup Procedure (Section 1.2) is the best method with which to
position your loudspeakers. Start with the speakers about 18” from each wall and, if
you need to move them relative to the side wall, move them away from the wall, not
closer.
A very important aspect of speaker placement is how far from the back wall to
place the speakers. The closer a loudspeaker is to the back wall, the more pronounced
the low bass energy and centering of the image will be. However, this comes at a defi-
nite reduction in stage size and bloom as well as a deterioration of upper bass quality.
You must find the proper balance of these two factors, but remember, if you are partial
to bass response or air and bloom, do not overcompensate your adjustments to maxi-
mize these effects. Overcompensated systems are sometimes pleasing in the short-term,
but long-term satisfaction is always achieved through proper balance.
