Crescendo Series
INTRODUCTION
You have invested in one of the finest speakers
available. Your Infinity Crescendo Series speakers
employ new technology in driver, crossover and
cabinet construction which places it at the fore-
front of current speaker design. As with any high
UNPACKING
quality product, special care must be taken to
install and operate your new speakers. It is for this
reason we suggest you read this manual carefully
from cover to cover prior to installation.
Upon opening the carton, inspect the speakers
carefully for any sign of transit damage. If there
is damage, immediately call your dealer or the
trucking firm that made the delivery. Do not delay
ASSOCIATED COMPONENTS
in reporting the damage because the longer you wait,
the more difficult it will become to file a claim.
It is suggested that you fold the carton flat and
store it for future use.
Your Infinity Crescendo Series speakers make
up a highly musical system. Like all loudspeakers,
they will reproduce distortion as well as music.
For this reason, the choice of associated audio
components is critical and should be made with
care. If you are replacing existing speakers with
an Infinity Crescendo Series System, there should
be an audible improvement in sonic quality,
assuming your other components are at least on
a par with Crescendo in terms of low distortion,
phase linearity, frequency response, and so on.
If no improvement is heard, or if the sound
deteriorates, it is possible that one (or more) of
your existing components is of a lower standard
than your new Infinity speakers. When a speaker
system is exceptionally revealing, musical color-
ations and other forms of distortion become more
noticeable because these aberrations are no longer
masked by the speaker.
Here are some suggestions which will prove
useful in obtaining a well-balanced audio system:
» Employ an amplifier with as much power as
possible. Since quality speakers work best when
driven by a high current, the choice of an
amplifier with a strong, adequate power supply
and a heavy-duty and rugged output stage
generally results in cleaner, better defined bass
response. And, while low distortion, excellent
phase characteristics, and low noise are all
extremely important performance parameters,
sufficient power into a low impedance load on
a continuous basis is equally important.
» Another consideration is that a lower power
amplifier operating at its maximum power
output can damage a speaker more quickly than
a high power amplifier playing at loud sound
levels. This occurs because many amplifiers
"clip" their output very "hard" when over-
driven, creating high frequency distortion
which can cause the voice coil of a tweeter
to heat and eventually fail. Always choose an
amplifier with high power. Your authorized
Infinity dealer can best answer your questions
and make recommendations.
» The Crescendo Series speakers are extremely
revealing and will quickly identify sonic
anomalies within the listening system. Poor
quality speaker cables and component inter-
connects can add harshness, detract from
spaciousness and reduce airiness surrounding
instruments and voice.
