The ear can differenciate between the direct sound and the reflexions when the time delay is sufficient. With a
small delay the reflections appear to be added to the direct sound. This ability of the ear is crucial for spacial
listening.
The loudspeakers should be positioned in a way to maximise the delay between the direct sound and the first
reflections. This means, the difference in distance between the direct and the reflected sound path must be as
high as possible. The more reverberant the room acoustic is, the more important this rule becomes. Short
reflections can be damped with special acoustic damping material.
The direction of the first reflections has also a certain effect. In the first example some reflections come from the
front wall. The sound stage will seem deeper. In the second example more reflections come from the sidewall.
The sound stage will seem wider. It is recommended to play with such effects to optimize the subjective sound
impression.

The following schemes show the variety of possible placements for the loudspeakers. Not all positions give the
same sound quality. Each room must be considered separately. Our room acoustic services can advice you in
special cases and for demanding projects create a complete design.
