ROOM ACOUSTICS AND SPEAKER PLACEMENT
Mirage loudspeakers have been designed to provide high performance in a wide variety of domestic settings.

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.
