_Special Twenty-Five
Care and maintenance
To maintain the aesthetic quality of the
Special Twenty-Five loudspeakers for
the long term, placing such into a very
warm, very cold, or very humid environ-
ment should be avoided. Direct sunlight
or excessive brightness can affect the
colour of any natural wood veneer, but
will not affect the quality or integrity of
the cabinet.
The cabinet and other plain parts should
be cleaned with a soft dry or slightly
damp cloth. Please avoid any aggressive
cleaning fluids. Dust on the woofer dia-
phragms may be removed with a fine
furniture brush. Avoid touching the
tweeter domes, as any change of their
shape may have an impact on sound
quality.
For safety reasons, please switch off all
the components of your system when
cleaning any of these components.
A cloth grill is included and can be secu-
red to the cabinet to help protect the
drivers. While the grill is acoustically
optimized, the highest sound quality
levels will be attained without the grill
covers in place during listening.
All materials used by Dynaudio are inte-
grated into the Special Twenty-Five with
exceptional care. By taking care of your
Special Twenty-Five, you will preserve
the finish and build quality for a very
long time.
Running-in the loudspeakers
The moving parts of a newly manufac-
tured Special Twenty-Five loudspeaker
have been acoustically checked after
production, but nevertheless are not as
flexible as they need to be for optimum
performance results to be realized.
The higher the quality of any driver
system, the more demanding the loud-
speaker will be regarding time for run-
ning-in the system. A newly unpacked
Dynaudio loudspeaker therefore requi-
res several weeks running or playing in
order to reach its optimum performance
capability. After that period, a couple of
minutes before every listening session
will be helpful to ‘warm up’ the loud-
speakers.
Power rating
Due to the construction and the driver
technology, the Special Twenty-Five
loudspeakers can be driven with very
high power levels. With a high quality
amplifier, delivering undistorted signals,
the speaker can achieve high volumes
without any compromise in sound qua-
lity.
Also, as the Special Twenty-Five has a
relatively high sensitivity, even high qua-
lity amps with a low power rating can
drive the loudspeaker to yield excellent
results.
Attention must be given to amplifiers
with very low power and adjustable
tone controls or switches. These types
may soon overreach their own perform-
ance limits and may send distorted out-
put signals to the speakers, compromis-
ing even high quality technology.
Any damage caused under such circum-
stances is not covered by the Dynaudio
warranty and is easily avoided in the
first place by consulting your Dynaudio
dealer for advice regarding the choice of
amplifier.
