ROOM ACOUSTICS AND SPEAKER PLACEMENT

Mirage loudspeakers have been designed to provide high performance in a wide variety of
domestic settings. It is important to note however, that building structure, dimensions
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 Mirage 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.

characteristics, and it is
important for good stereo
