ROOM ACOUSTICS AND SPEAKER PLACEMENT
Energy loudspeakers have been designed to provide high performance in a wide vari-
ety of domestic settings. It is important to note however, that building structure, dimen-
sions and furnishings all play a part in the quality of sound you will ultimately achieve.
Where possible the following should be taken into consideration when placing
Energy
speakers in your listening room:
1. Low frequency performance (below 100 Hz) can be affected by the structure of the
room.A solid floor is preferred to avoid exaggeration of low frequencies.
2. Rooms with different height, width and length are preferable for best low frequency
performance.
3. Mid and high frequencies are affected by the mix of soft and hard furnishings in the
room.An excess of soft items such as curtains, carpets, sofas and wall coverings can
produce a dull, lifeless reproduction.The same room without any soft furnishings will
produce a brighter, harder sound, so a balance of soft and hard furniture, floor and
wall coverings should be your goal for optimum sonic performance.
4. Most of the sound heard from a loudspeaker has been reflected from one or more
walls of the room. Usually, less than half the sound is heard directly from the
loudspeaker.The remaining information you hear has been reflected from the
surfaces of your room.
Reflective surfaces have individual sound absorption characteristics, and it is
important for good stereo perception that frequency response be the same from
both left and right channels. It is therefore important that consideration be paid to
the left and right reflecting walls. First, they should be symmetrical, equally spaced
from the speakers and the listeners. Secondly, they should have the same, or very
similar reflective properties. Example: A curtain on one wall and a painted surface
on the opposite wall will result in unbalanced reflections, which in turn affect the
stereo image. Experiment with toe-in/toe-out positioning of your speakers until best
results are achieved.
5. Audissey Bipolar loudspeakers are designed to be free standing.They should
therefore be positioned with an open space between the loudspeakers and the
walls of the listening room.
6. The distance from the left and right speaker to the side walls should be equal. For
best results, placement distance from the rear wall should not be the same as from
the side walls. (see figure 1).
