Loudspeaker And Listening Position - Wilson Benesch FIBONACCI Series User Manual

2.4 Loudspeaker and Listening Position

The system, comprised of different components, installed in a room with a unique acoustic character and every listener's individual taste, should be appreciated as a
unique sum comprised of a great many variables. It should be considered that in this balancing act experimentation is critical to getting the best from the system and
more importantly, tuning to the listener's own satisfaction. There is no one simple set of rules for speaker placement that will fit for every scenario within which a Wilson
Benesch loudspeaker is installed. It is for this reason that no minimum or maximum parameters are stated for the positioning of each product. The listening position
should also be evaluated in the same manner.
The distance between the speakers in relation to the distance from each speaker to the listening position will impact on the size of the sound stage presented.
Additionally, if the listening position is moved closer to the speakers, the proportion of reflected sound to direct sound will decrease. A great many recommendations
describe an equilateral triangle, whereby the distance between each speaker and the listening chair are the same, but again, experimentation is the key. A larger distance
between the speakers can result in a larger and more engaging presentation. The distance between the speaker and rear and side walls, should also be considered. Bass
performance in particular will often suffer wherever a speaker is too close to one of these boundaries, resulting in "boomy" or over-bloated bass and/or cancellations.
This affect is more pronounced still, when placing the speaker into a corner where two boundaries meet.
The most valuable commodity in this process is time. Be prepared to make small changes over long periods of time. Wiring up the loudspeaker and commencing the burn
in period is advisable. Whilst optimal setup cannot be achieved without completing the burn in period, it is generally possible to gain some understanding of how the
loudspeaker is integrating within the room during this period and start to experiment with positioning.
Once the 168-hour running in period has elapsed, the final positioning and fine tuning of the system can begin in earnest. Parameters such as toe and rake angles should
yield quite marked changes in the presentation.
We would recommend selecting four musical passages as outlined below in helping you evaluate the various speaker positioning parameters and the effects of changing
these.
-Select one with a distinctive and easily heard human voice. Spoken voice is ideal.
-Select one passage with a full orchestra like The Pines of Rome.
-Select one that is very emotional for you.
-Select one that has a strong rhythm and a good portion of bass content, as found in a typical dance music track for example.
