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.

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. Spiked feet are recommended for stability on carpeted floors.

6. The loudspeakers should be placed 2 to 3 meters (6” to 10”) apart and

approximately 1/2 meter from the wall behind the speaker.The distance from loudspeakers to listener should be about 1 to 1.5 times the distance separating the speakers (see figure 1).

Selection of Proper Wire

We recommend the use of high quality speaker cable.The speaker cable you select will ideally be fitted with high quality connectors with either 5/16” spade lugs or dual banana plugs.

In most installations, ordinary lamp cord (16-18 gauge) has enough resistance to degrade the signal between amplifier and speakers, particularly in lengths over 3 meters (10’). If possible the speaker cables should be the same length for both channels and the shorter they are, the better the sonic performance will be.

* When connecting your speakers to your sound system, turn off your

amplifier to avoid damage which could result from shorting of the speaker leads.

Amplifier Requirements

Mirage loudspeakers have been designed to be driven to high listening levels with moderate power, while at the same time being capable of handling the power output of large amplifiers.

NOTE: Mirage 90is Series speakers are 8 ohms nominal and will function well with quality amplifiers.
