Speaker Orientation
Speaker placement and orientation are two of the most important consid-
erations 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 music. Adhering to the Wilson Audio Setup
Procedure outlined in the previous section is the best method with which to
position your loudspeakers.
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 definite reduction in stage size and bloom as well as a deteriora-
tion of upper bass quality. You must find the proper balance of these two fac-
tors, but remember, if you are partial to bass response or air and bloom, do not
overcompensate your adjustments to maximize these effects. Overcompensated
systems are sometimes pleasing in the short-term, but long-term satisfaction is
always achieved through proper balance.
To make correct in-home set up of the Alexx possible without test equip-
ment, Wilson Audio has measured the correct geometric time domain alignment
for different distance/ear height combinations. See the next section for details.
