Introduction
Thank you for choosing AAD loudspeakers.
Their refined and natural sound character will
greatly enhance your listening pleasure. Great
attention to detail has gone into the design and
manufacturing of AAD loudspeakers, which
are built with only the finest materials. They
will provide many years of excellent
performance.
By using many proprietary components, The
C-Series is the result of concentrated efforts
to combine superior sonic performance with
exceptional aesthetic design to suit the
modern living environment. Some of the
features of C-Series include:
Smooth and extended frequency response.
The AAD speakers are able to produce
wide musical range from bass through
mid-range frequencies and up to the
highest frequency beyond human limits.

modest amplifiers will be able to produce

amplifiers with substantially more rated

Superior transient performance. The
speakers are able to give definition to

triangles, all of which will be reproduced

stage.
Compatibility and flexibility. The C-Series
includes many models of bookshelf, centre
channel, floor standing, rear surround
speakers and subwoofers in various sizes
to provide maximum flexibility for
different home theater 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 will meet your

personal needs.

Placement
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
Two Channel Stereo Application
distance from your listening position.
Bookshelf systems will also benefit from
placement on stands or shelves. The C-Series
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.
Please refer to Table 2 for different system
configuration depending on room sizes.
Multi - Channel Application
To get the best surround sound from your
C-Series speakers, we recommend to position
the speakers at the same distance from the
listening position.
The center 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 center or rear speakers
farther away from the listening position
When mounting the rear speakers on side
walls perpendicular to the listening position
they should be placed 60~90 cm above the
listener's ear level at sitting down position.
than the front speakers.
Depending on the shape of your room,
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.

terminals accept spade plugs, bare wire or
banana plugs. For best results, use high quality

speaker cables.
Single Wiring
This method uses only one pair of cables to
connect each speaker to the amplifier. ( as
shown in Figure 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 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 ( as shown in Figure 2 ).
Connect the speakers to amplifier the same
manner as you do single wiring.
Note: remove the metal links.
Adding center 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

channel stereo speakers, connect left and
right, center, 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.

Instead of a normal suspension construction, the
AAD Fixed Suspension Midrange ( FSM ) uses
an innovative design. The small movements of
the cone lightly compress and stretch the ring.
Because the ring's surface area is small, it
radiates relatively little sound, and what little
movement it does have always follows the cone
Firstly, the whole cone begins to respond much
quicker in a given time. In the time domain this
equates to a better transient response. In the
frequency domain it indicates a more extended
high-frequency response, and indeed the
response of this driver is smoother to higher
frequencies and allows a better-integrated
edge because it is so tightly coupled.
