After Installing the Speakers
To obtain the best possible
sound quality
Break-in or aging effects
The sound quality of the speaker will continue to improve
during an extended breaking-in (aging) period.
The length of time required for the SS-M9ED to reach its
optimum or ideal level of performance will vary from case
to case.
On average, however, it will be about 100 hours of typical
listening. This period need not be continuous, but can be
an aggregate of multiple listening sessions of about
3 hours each. During this period, the volume level should
be set at a reasonable listening level.
If you use pink or white noise for the break-in, you should
set the volume to a level lower than what would be
typical in order to avoid thermal stressing of the internal
speaker components.
Recommend amplifiers
We recommend the Sony TA-N1 for the power amplifier
and the Sony TA-E1 for the stereo pre-amplifier.
In this manual, the TA-N1 is used for illustration
purposes. If you use another amplifier model, we
recommend that the amplifier be as high quality as
possible and that it has the following specifications:
• 4-ohm load-impedance speaker output.
• A rated power output of not more than 400 watts.
Speaker cords
The sound quality of the speaker system is largely
determined by the quality of the speaker cords. Since the
sound quality of the SS-M9ED is especially sensitive to
even slight differences in speaker cords, you should
choose high-quality speaker cords that suit your personal
taste.
The speaker cords should be as large in diameter as
possible and only as long as is necessary. We recommend
that you use cords that are less than 3 meters in length
and have spade-type termination.
You should also keep the speaker cords away from all AC
power cords.
Super-tweeter
The super-tweeter on top of the speaker cabinet has the
ability to reproduce very high audio frequencies of up to
100 kHz, and is thus designed to support the coming
generation of audio sources. Since high frequencies above
20 kHz have extreme directivity, the super-tweeter can be
laterally (horizontally) adjusted up to ±15 degrees to suit
your listening taste.
Front grille
The front grille on the SS-M9ED can be removed to for
better sound quality.
If you remove the front grille, however, you should take
care not to touch the speaker domes. Keep the removed
front grille in a safe place to avoid deforming it.
Note that the super-tweeter grille is not removable since
the dome material is extremely fragile.
