Precautions
$Before connecting the subwoofer unit to a power outlet, make sure that the operating
voltage of the local power supply is identical to that specified for the subwoofer.
$Ensure that your amplifier is switched off, before connecting the speakers.
$Turn off the subwoofer before connecting the input signal cable on its internal amplifier.
$Make sure that you have connected the plus (+) and minus (-) terminals of each speaker
to the corresponding plus (+) and minus (-) terminals on the amplifier.
$Make sure that all screws on the binding posts are tight enough, especially if you are
using bare speaker wires. A contact between bare speaker wires may cause short-circuit and
potentially damage your equipment.
$Avoid the use of your amplifier in its power limits. Especially, in the case that your
amplifier is of low power, the continuous use in high power levels can cause distortion of the
signal, amplifier clipping and may cause severe damage to your speakers
$Therefore, high power amplifiers are more preferable.
$Do not drive speaker units with a continuous wattage exceeding the maximum power
indicated in this instruction manual for each speaker model.
$Use the best speaker and interconnect cables you can afford.
$Do not place loudspeakers in dusty or humid environments.
$Avoid exposure to direct sunlight.
Caution: Your SmArt speakers come with electronically protected tweeter in order to avoid
problems of overheating that can cause their destruction.
However for even greater protection, avoid extremely high volumes in your amplifier that can
distort your sound signal or cause severe damage to your amplifier and your speakers.

1. Introduction
Congratulations!!!
Your Crystal Audiovideo speakers are built to the highest specifications standards meet-
ing any technological requirements for Hi-End sound reproduction at any price.
You will experience state of the art multichannel sound performance as the director of
the movie or the creator of the music tune intended. Crystal Audiovideo speakers provide
every music note of enjoyment that you expect from high performance speakers, and that you
paid for.
1.1 SmArt Systems with THX-SUB Speaker System
SmArt Speakers are designed to be used perfectly with the THX select certified
Subwoofers offering that way supreme THX quality in affordable prices. SmArt speakers are
not THX certified because of their small shape and the set of the amplifier's crossover at 120
Hz instead of 80 which is the requirement for the THX certification.
SmArt speakers have the extra ability to change their side panels making them able to
change colour whenever you change decor without having to change the entire speaker sys-
tem! Just remove the side panels as you remove the grille from the speaker, replace them
with new ones of different colour and your speaker will transform to a new one according to
your aesthetics!
The sound integration is excellent with your THX-SUB subwoofer supporting flat anechoic
response from 35Hz to 200Hz and accurate in room response from 19Hz to 350Hz. So they
reproduce either the sound of music or movies with the authority of larger and more expen-
sive speakers.
Your SmArt & THX-SUB System not only use THX technology for the low frequencies but
also the best Hi-End 'Small' Towers for the mid and high frequencies supporting:

1.1.1 SmArt Speakers
Your SmArt system is available in 2 different versions that include the following speakers:
SmArt 8 System
1.
2.
$SmArt Tower Speakers with 8 woofers for the front and surround channel.
$SmArt-4 Speakers for the center channel.
SmArt 4 System
$SmArt Tower Speakers with 4 woofers the front and surround channel.
$SmArt-4 Speakers for the center channel.
2. Positioning your SmArt Speakers
The sound fields generated by a multichannel audio system surround the audience
and create a three dimension audio image. In order to get the maximum accuracy and fidelity
that you have paid for, you should follow a careful set-up procedure. You will always be
rewarded.
$Ideally the five speakers are equidistant from the listener and generate identical sound
levels when fed an identical signal.
$In real life the speakers may not be equidistant; time delays must be employed, ensuring
that sound from all speakers arrives to the listener's ears at the same time. The sound field
must be homogeneous and controlled.
SmArt & THX-SUB speakers will provide Hi-End performance multichannel sound in small
to medium size rooms.

2.1 Placement of SmArt-Tower for Front Right and Left Channels
Always follow the rule of thumb as is shown in figure 1 (page 5)
1.
2.
3.
Place your SmArt speakers equidistant from the TV/Projector screen.
Measure the distance between your Left and Right speakers (LR).
Measure the distance between your listening position and the middle point between your
Left and Right speakers (PM).
4.
5.
The difference in length of the above distances should be no more than 15%.
Angle your speakers inwards and towards the listeners. Find the optimum angle that pro
duces the best sound.
6.
Adjust your speakers so that the tweeters are at about the same height as your ears when
sitting at the listening position - if possible.
7.
To reinforce lower frequencies move the speakers towards the room boundaries. To reduce
lower frequencies do the opposite
8. Do not spread your speakers too far apart otherwise you get a hole in the center image.
9. Do not place your speakers too close together otherwise the sound stage collapses into a
fuzzy mono sound.
2.2 Placement of SmArt-4 for center channel
$TV screen: Place your SmArt-4 speaker directly above or below the screen wherever is
closest to ear level.
$Projector screen: Place your SmArt-4 behind or in front of the centre of your screen
whether the screen is acoustically transparent or not.
2.3 Placement of SmArt Speakers for Surround Right and Left Channels
Your SmArt speakers are also used for the surround channels and are optimized to offer an
enveloping surround field.
1.
2.
Place the speakers slightly behind the primary listening position.
Adjust the speakers to fire towards each other behind the seating area.

2.4 Placement of SmArt-4 on the wall
Because of their smart design the SmArt-4 speakers can also be placed on the wall as a
center (horizontal placement) or a surround speaker (vertical placement).
Additionally, by removing the side panels it can be enwalled making its appearance even
more diacritic.

3. Speakers Connections
IMPORTANT
All connections
should be made with
the equipment
switched off.
Figure3: Speakers Connections
Connections to the loudspeaker system are made at the terminals located at the rear panel of
the enclosure. These terminals permit a variety of connection methods.
1. Single - wire: ensure that the positive terminal on the speaker (marked + and
coloured red) is connected to the positive output terminal of the Receiver. Similarly, the neg-
ative speaker terminal (marked - and coloured black) should be connected to the negative
Receiver terminal. Incorrect connection can result in poor imaging and reduced bass output.
Bi - wire:
2.
remove the links by loosening the speaker terminal caps and use a separate
2-core cable from the Receiver to each pair of terminals. This can improve the resolution of
low-level detail. Always observe the correct polarity. When bi-wiring, incorrect connection can
also impair the frequency response.
Make sure that you choose the correct output speaker terminals on your Receiver to con-
nect your SmArt speakers.
For the front left and right speakers:
$
Use the front right and left speaker output termi-
nals on your Receiver to connect two SmArt-Tower speakers.
For the center speaker:
connect your SmArt-4 speaker.
For surround speakers:
$
Use the "center" speaker output terminals on your Receiver to
Use the two "surround" speaker output terminals on your Receiver
$
to connect two SmArt-Tower or your SmArt-4 speakers.

$Proceed to the

hearing position). For further details consult your amplifier's manual.
$Adjust the crossover frequency between 120Hz and 150Hz on the Crossover Frequency
Control
of your Receiver. Setting the crossover frequency at 120Hz ensures better perf
ormance of the Subwoofer making it more flexible to place in different locations in your
room. Setting the crossover frequency at 150Hz ensures bigger output power with the
restriction that the subwoofer is placed near the speakers.
$The adjustment of crossover frequency is taking place through a technique that is
called bi-amplification, resulting in the improvement of the frequency response of a home
cinema. Additionally bi-amplification lowers the signal distortion and increases the
dynamic area. Through that technique, the lower frequencies are being amplified exclu
sively by the built-in subwoofer's amplifier.
Note:
For further details according to the proper adjustments and placement of THX-SUB in
space, please refer to the subwoofer's manual.
