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 Trio 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 
Trio output produces a fl at 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 
per for mance from your Home Theater. If 
you do not have a subwoofer connected, 
you will be missing the 5.1 LFE (low 
frequency effects) information.
Break-in period
Like many high performance automo-
biles, the Cinema Ribbon Trio loudspeak-
ers perform at their best after an initial 
break-in period. A minimum of 20 hours 
is recommended prior to performing 
critical listening, however the speakers 
will sound their best after a period of 300 
to 400 hours. During this time, the driver 
suspensions and ribbon structure will 
relax into their operating design positions 
and give optimum performance.
To facilitate break-in during the initial 
20 hours, it is recommended that you 
play material with a wide dynamic range 
at louder volumes – such as your favorite 
rock and roll album (that is if your family 
or neighbors can stand it).
It is important that your amplifi er 
must supply good clean power, 
and not run into distortion. Amplifi er 
distortion due to clipping, causes 
high-frequency output components that 
can damage loudspeakers. Even a 100 
watt amplifi er running into clipping can 
damage loudspeakers rated at 400 watts 
or more.
NOTE: If your processor or preamplifi er 
does not have a crossover control, you 
might need an external active crossover 
to split the audio signal into a low-pass 
range for the subwoofer, and a high-
pass range for the Cinema Ribbon Trios. 
(Sunfi re subwoofers have their own 
crossover controls with line-level high-
pass outputs that can be used to power 
an amplifi er connected to Cinema Ribbon 
Trio loudspeakers.)
