4. Precise stereo imaging. Close tolerance pair matching of drivers ensure a stable
stereo image. Minimal phase crossovers ensure great depth and width of the sound
stage.
5. Compatibility and flexibility. The C Series-3G includes many models of bookshelf,
centre channel, floor standing, rear surround speakers and subwoofers in various
sizes to provide maximum flexibility for different home theatre and stereo
application. No matter what your requirements are and type of room you have, a
custom designed system by using speakers from the C Series-3G will meet your
personal needs.

Placement
Two Channel Stereo Application
For stereo listening, you may choose any one pair of bookshelf or floor standing model.
The size of speakers should be determined by the size of your living space so that they
can provide sufficient volume. The two loudspeakers should be placed an equal
distance from your listening position.
Bookshelf systems will also benefit from placement on stands or shelves. The
C Series-3G stands are designed to match the bookshelf speakers functionally and
aesthetically.
Placing the loudspeakers in corners or against a wall will result in the strongest (but
not necessarily the most accurate) bass. For the best stereo imaging, we recommend
that the systems be placed so that the high frequency transducers are as close as
possible to the ear level of a seated listener.
Every room has different acoustic characteristics and people have different tastes in
sound. You should experiment to find out the placement position that satisfy your
personal tastes.
Home Theater Application
To get the best surround sound from your C Series-3G speakers, we recommend to
position the speakers at the same distance from the listening position.
The centre speaker, however, may be moved closer, but not beyond the straight line
connecting the two front speakers. The rear speakers may also be closer to listening
position than the front speakers to suit the configuration of your room.
Notes:
-
Do not place the centre or rear speakers farther away from the listening position
than the front speakers.
-
When mounting the rear speakers on side walls perpendicular to the listening
position they should be placed 60-90cm above the listener's ear level at sitting down
position.

Depending on the shape of your room (etc.), you may wish to place the rear speakers
behind you instead of on the side walls. In this case, you can use a pair of large floor
standing speakers matching your front speakers.
Connections
Note: Make sure your amplifier is off and disconnected from power while you are
connecting speakers to amplifier. Turn your amplifier on only after you check and
make sure speakers are properly connected.
Two Channel Stereo Application
Connections are made at the terminals located on the back of the loudspeaker system.
The terminals accept spade plugs, bare wire or banana plugs. For best results, use high
quality speaker cables.
All C Series-3G loudspeakers have 4 gold plated binding post for single or bi-wring
options.
Single Wiring
This method uses only one pair of cables to connect each speaker to the amplifier. (see
Fig. 1).
For each channel, the red terminal on the loudspeaker should be connected to the red
or (+) loudspeaker connection terminal on the receiver or amplifier. The black
terminal on the loudspeaker should be connected to the black or (-) loudspeaker
connection terminal on the receiver or amplifier. Connecting the loudspeakers in this
manner ensures that they will be in phase; that is work together rather than in
opposition. Connecting the loudspeakers out of phase will not damage them, but will
result in less bass and poor imaging.

Note: make sure the metal links are in place.
Bi-Wiring
Bi-wiring increases the flow of current and will usually improve the sound quality.
This method uses two pair of cables: one pair for the upper two terminals and one pair
for the bottom two terminals (see Fig. 2).
Connect the speakers to amplifier the same manner as you do single wiring.
You will need one pair of cable for each speaker in the system.
Note: remove the metal links.
Home Theater Application
Adding centre and rear speakers to the left and right channels will enhance the
surround effects of motion pictures. If you choose smaller models, an active sub-
woofer is essential for adequate bass reproduction.
On the back panel of your AV amplifier, locate the Front Speaker, Centre Speaker, and
Rear Speaker terminals.
Using the same method as connecting two channel stereo speakers, connect left and
right, centre, and rear speakers to the corresponding terminals on the AV amplifier.
Again, be sure to match the speaker cables to the appropriate terminals on the
components: (+) to (+) and (-) to (-) to ensure sufficient bass and clear imaging.
Adding a subwoofer to your home theater system will greatly improve bass
performance and provide fuller impact from motion pictures. We recommend C-11
subwoofer for smooth transition and configuration.

C-11 Power ed Subwoofer
Owner 's Infor mation
Impor tant Instr uctions
1. Read your owner's manual carefully before using the product. Retain this manual
for future reference.
2. The subwoofer should be placed at a ventilated, dry and cool location, away from
any heat sources such as radiators or amplifiers. Do not obstruct the amplifier in
the C-11 from ventilation. It is necessary that air can flow around the finned heat
sink on the rear panel of the amplifier.
3. Do not use the subwoofer near water or expose it to rain or moisture.
4. Always unplug the power cord first when making connections. Switch power on
only after you check and make sure all connections are made correctly.
5. Unplug the power cord from the outlet when you are not going to use the
subwoofer for a long period of time.
6. To clean, unplug the power cord from the outlet first. Use a damp cloth only to
wipe dust off the surface. Do not use any liquid cleaners.
7. Do not put coffee cups or other objects on top of the cabinet. They can be shaken
off when the subwoofer is in operation as it can produce a lot of vibration.
Intr oduction
C-11 is a home theater subwoofer equipped with a build-in equalizer. The
5-
band equalizer is a powerful tool in correcting anomalies of subwoofers caused by
room acoustics. It will greatly increase subwoofer performance when used properly.
In the real world, subwoofers generally do not have a flat frequency response. Only
in ideal conditions such as open air or large anechoic test chambers do they have a
perfect response measurement. When a subwoofer is played in a listening room, the
bass frequencies can be up or down 10 dB from the ideal response. The sound can
have a “boomy” or ill-defined bass that will impair the overall musical performance.
The
5-band equalizer is designed to control offending bass notes that “booms”
louder than they should. It features precisely aligned 1/3-octave equalization filters
that are only found on the best professional audio equipment.
The cabinet has been designed using extensive computer modeling for the best
possible alignment between driver and box. Coupled with two high excursion

proprietary 8” drivers, the C-11 produces clean, powerful and controlled bass. Three
large rear-firing vents ensure ventilation of both driver and amplifier for cool
running at high power. The vent's large bore and “gas flowed” cross-section reduces
air turbulence that causes audible distortion.

Power switch on/off
Upper position: Power on
Lower position: Power off
Middle position: Auto on
At this position the subwoofer amplifier is in a stand by mode, awaiting an input
signal. When there is no signal, the amplifier is shut down. As soon as the signal
appears, the amplifier switches on. If signal is absent, the amplifier will shut
down automatically after a pre-determined period of time. The power indicator
is red when the switch is at OFF position, and green when the switch is at ON
or AUTO position.
Volume Contr ol
Use this control to balance the level of the woofer with the level of your main
speakers.
Cr ossover Fr equency control
If you are using small loudspeakers (4”to 6” woofers) in your main system, you
will need to set the crossover frequency at a high position (100 to 160 Hz). If
your main speakers have larger woofers (8” and above) you will need to set the
crossover frequency to much lower position (40 to 80 Hz). Generally, the larger
the speaker, the greater the low frequency output will be. If the frequency
control is set too high, the bass will appear “boomy” due to outputs of
subwoofer and main speakers overlapping each other. If it is set too low, the
bass will be ill defined and the subwoofer will sound detached from the rest of
the system.
Phase Contr ol
Use this control to determine the best possible bass performance of your system.
There can be interference between your main speakers and subwoofer at the
frequency where they cross over due to placement, room acoustics and type of
main speakers used. By carefully positioning the subwoofer in the room in
combination with the level and crossover control, you should be able to get a
seamless transition between your main speakers and subwoofer. Start with the
full anticlockwise 0 position. This means that the subwoofer will push out
positive pressure wave corresponding to a positive electrical input. The
180 full clockwise position inverts this so the subwoofer will put out a negative

pressure wave. You can use this position if you are unable to get a good
integration between the subwoofer and main speakers.
Equalizer on/off
At “off” position, the amplifier will function normally without the effect of the
5-band equalizer.
5-band Equalizer
Please refer to “Setting up EQ for the Room”
High Level Inputs L&R
These inputs should be connected to the left and right speaker terminals of your
amplifier/receiver, if you intend to connect the subwoofer using this option
instead of the low-level RCA input connections.
8
High Level Output L&R
You could connect your main speakers from the subwoofer amplifier instead of
the main amplifier/receiver. Use this option if you are connecting the
subwoofer up via the High Level Input.
CAUTION! Do not use both low level and high level connection methods
simultaneously. This may cause damage to the subwoofer and your
amplifier/receiver.
Low level Input & Output
Connect this to the pre-amp output of your amplifier/receiver. If you do not
have a pre-amp output or a power amplifier input, you can connect up the
subwoofer using the Low Level Input/Output utilizing a tape input/output
amplifier/receiver. Connect the tape output to the Low Level Input on the
subwoofer, then connect the tape input to the Low Level Output on the
Subwoofer. To switch the subwoofer into the circuit, switch the tape monitor
input on your amplifier/receiver.
Use this in conjunction with your receiver/amplifier. Connect this output to the
power amplifier input of your amplifier/receiver.
Power input socket and Fuse
For continued protection, replace only with same type fuse. (A spare fuse is
enclosed for replacement.)

Setting up EQ or the Room
Play some familiar pieces of music that have prominent bass lines. Start with the EQ
switched out and then adjust the EQ filters one by one switching the EQ in and out. It
is better to start with the EQ cutting the frequencies and not boosting them.
Remember that a 10 dB boost is adding ten times the power at that frequency so it
would be easy to overload the system at high power levels with the EQ sliders set at
maximum.
Room Size and Room Position
The size of the room and the position of sub-woofer placement will also determine
low frequency limit of the subwoofer. So by adjusting the EQ settings, the ideal
response can be obtained without having to place the subwoofer in an unpractical
location. Small rooms usually add gain to low frequencies, which can be
overpowering to the rest of the music. Large rooms need greater low frequency
energy to sound balanced. The EQ settings can be adjusted to fit the room size. The
5 band equalizer should be used with great caution. The power levels to the speaker
can be boosted by as much as 10 times! So if the subwoofer is running at 100 watts
the EQ boost at maximum will try to push the amplifier to an impossible 1000 watts!
Although the amplifier and speakers are designed to handle overload conditions it is
still possible to cause damage from mis-use.
Placement of Subwoofer
The subwoofer can be placed virtually anywhere in your room without affecting the stereo
image of your main speakers. Placing the unit in a corner of the room will yield the greatest
bass output but may not provide the best sound, as this position will cause maximum room
mode resonance. You can start with this position and then move the subwoofer to different
areas until you find the sound satisfactory. The best method is to try different positions.
Keep a clearance of 100mm/4” from the wall or furniture to provide best performance.

Gener al Car e
The loudspeaker cabinet may be cleaned with a slightly damp cloth. Grilles should be kept on
the speakers to protect the drive units when the speakers are not being played. Never use any
solvents to clean any part of the system.
The grille is held in place by pins near the edges. To remove the grille, grasp it by both
top and bottom edges and pull gently. To replace the grille, reposition it carefully and
press gently at the corners. Do not push on the center area of the grille. Keep the grille
free of dust and dirt. To clean, remove the grille from the cabinet and vacuum lightly.
