7.1 Widening the Stereo Field
We generally recommend angling the speaker axes in towards the listening position to create an
equilateral triangle as described above. This yields the most accurate high frequency response and the
sharpest stereo image at the center listening position. In some cases, however, the listener might
change positions frequently. Or there might be multiple listeners. In such situations it may be
desirable to have a wider and less focused stereo field which provides better coverage over a range of
listening positions. This can be achieved by aiming the speaker axes more forward such that the axes
cross further behind the center listening position. The figure below illustrates the general principle
and is not meant to be an exact measure of speaker angles or optimal listening positions.
Since the Footprint01 has such wide off - axis dispersion, the horizonal angle relative to the listener can
be changed by up to 10 degrees with less than 1 dB variance in the frequency response across the
audible spectrum. Angling the speakers forward in this manner will somewhat defocus the center
stereo image while providing generally better imaging over a range of listening positions. For some
users this may be an acceptable compromise.
