RECOMMENDATIONS
GENERAL RECOMMENDATIONS
Height
- To use Miles Bookshelf Speakers as stereo speakers from a fixed
listening area, the Speakers should be located at the ear-level of a listener who
is seated in the listening location.
Distance
- It is recommended that the distance between each of the Miles
Bookshelf Speakers be shorter than that from the speakers to a listener. For a
perfect sound quality, both of the speakers should be tilted inward toward the
listener.
Position
- For the ultimate sound performance, the speakers should be
situated in a vertical direction. If they are not in the ear-level of a listener i.e.
much higher or lower than recommended, they can be put on their side for
off-axis performance.
Amplifier Considerations
An amplifier should be well and carefully selected. The range of Miles
Bookshelf Speakers’ impedance is between 4 to 8 ohms. Thus, the amplifier
chosen needs to be able to support a 4-ohm load. For an amplifier with
a switch, it is required to set to select a 4-ohm compatible operation
mode. If an amplifier is not selected or setup properly, the amplifier or
the speakers can be damaged.
Amplifiers between 15 to 95 watts per channel can be used with the Miles
Bookshelf Speakers along with good care. In case audible distortion
occurs, it is suggested to turn the volume down until the distortion is
gone. Likewise, when there is audible distortion, it is required that the
speaker and amplifier not play for more than a few seconds.
Usage-Specific Recommendations
Bookshelf Speakers
To use the Miles Bookshelf Speakers as bookshelf speakers, the two
speakers need to be at the same hight as different heights of the speakers can
result in degrading sounds quality. Try to place the speakers as close to
the ear level as possible no matter the listening area is at a seated level
or standing level.
Stereo Speaker on Stands
Likewise, please make sure that the speakers are positioned at the ear
level of a listener when they are used with speaker stands. Therefore,
speaker stands with a proper height should be used. To calculate the
perfect ear level, measure the height of the listener’s ear when seated
in a listening area, then subtract 15 cm. For instance, if the listener’s
ear is 100 cm. from the floor when he/she sits, the appropriate height of
speaker stands will be around 85 cm. high.
Desktop Near-field Monitor
In addition, the Miles Bookshelf Speakers can be used as desktop/
near-field monitor speakers e.g., next to the side of a display or mixing
console. However, the Miles Bookshelf Speakers should not be located
close to CRT displays or other magnetic-sensitive equipment since they
are not shielded. In case placing the Miles Bookshelf Speakers at the
ear-level hight is not possible, it is suggested to use Monitor Isolation
Pads to tilt the speakers back or to decouple them from the desk level.
