The Cinema Ribbon CRW loud-
speakers are designed to be used
with a subwoofer to fill in the lower
frequency range. They are not
designed to accept 400 watts of power at
the full frequency range.
Your system should be designed so
that the Cinema Ribbon CRW loudspeak-
ers receive only the range above 80 Hz,
with a subwoofer to handle the frequen-
cies below 80 Hz.
Sunfire home theater processors and
receivers have a bass management sys-
tem that allows you to redirect the bass
frequency range of each channel to the
subwoofer. The advantages are :
• The overall bass of the system is
improved, as subwoofers, such as
Sunfire's powered True Subwoofers
are specially designed for this
frequency range.
• The subwoofer can simultaneously
play the bass from all of the loud-
speakers, in addition to it’s own low
frequency effects channel (LFE).
• There is no loss in perception of the
position of movie or music sound
effects, as the ear cannot easily
locate the position of bass sound
sources.
• Compact loudspeakers can be
used for front, center and sur-
rounds, as they do not have to
reproduce the low frequency range.
This leads to a saving in room
space.
• Your amplifiers do not waste power
reproducing the low frequency
range.
Using a subwoofer
Crossover adjustment
We recommend that you set your home
theater processor's crossover to 80 Hz,
and set the channels that use the Cinema
Ribbon CRW loudspeakers to "small."
• Your subwoofer receives frequencies
below 80 Hz, from all loudspeakers
whose size is set to small, in addition to
the LFE channel:
• All loudspeakers set to small, receive
frequencies above 80 Hz.
• Set your subwoofer's own crossover
control (if it has one) to maximum
frequency or bypassed mode. If it is set
lower than the 80 Hz, there would be a
hole in the mid-bass, and bass informa-
tion would be missing.
The acoustic summation of the
subwoofer output and the Cinema Ribbon
CRW output produces a flat frequency
response.
NOTE: Dolby Digital and DTS modes
are designed especially for complete
systems with front, center, and surround
loudspeakers and subwoofers. You need
all of the loudspeakers to get the best
performance from your Home Theater. If
