The speaker manufacturer…
…should be contacted for their recommendation regarding speaker setup for side by side, love seat listening. Usually sweet spots are not very wide. Another way to get a wide sweetspot is to defocus the otherwise crystal clear imaging that is normally found in high end rooms. This would be done by adding very early reflections, within a few milliseconds in the upper treble range.
I hope this 3 part series served as an adequate and interesting overview/ introduction to the mechanical aspects of developing a high end listening room. As you can see, there are strictly mechanical features, many visual/sonic aesthetic features and some strictly visual features to be resolved. It is a creative collaborative process that often included many compromises but the result never ceases to be amazing because we are building a room that brings the music to life.
