By overlaying the width and length graphs, we can
see the intersection points of the lines. These points
represent where the centers of the speakers should be
placed to minimize nodes and anti-nodes.

As you can see, we now have quite a few intersec¬
tions to choose from in our example room. Some of the
intersections in your room will probably be eliminated
by aesthetic or room function considerations, so you
probably will not have as many.
As you try different placements for your speakers,
always place both speakers on the same length line.
For example, both speakers would be placed on the 43
inch line or both speakers would be placed on the 24
inch line. The speakers can be placed on different
width lines, for example one on the 34 inch line and the
other on the 56 inch line. Placing the speakers on dif¬
ferent rather than matching width lines will require that
the listening position be offset to center it between the
speakers. Often, the bass response of the system will
be slightly more linear with the speakers placed on dif¬
ferent width lines, (asymmetrical placement) while the
imaging will often be better with the speakers placed
on matching width lines (symmetrical placement).

After listening to the speakers centered on the
charted intersections, you should listen with the
speakers a couple of inches away from the intersection
points in each direction. In some cases, the speakers
will sound better slightly off the intersections due to the
particular characteristics of your room or a slight error
in your original room measurements. Both speakers
should be moved the same amount forward or back¬
ward when fine-tuning placement.
