UNPACKING
After opening the top carton flaps, remove the grille. Then fold
the carton flaps right back and remove the speakers from the
carton. We suggest you retain the packing for future use.
POSITIONING
SPEAKER POSITIONING
Our speakers have been designed to function in a vertical posi-
tion. Under these conditions, the polar response is most uni-
form.
Speakers are delivered with a front grille to protect drivers. It is
possible to use them without this front grille, by gently pulling
on one side to remove the grille from its slot. To set the grille
back in place, insert one side of the grille in its slot then gently
bend the grille until the other side fits in its slot. These opera-
tions must be carried out very smoothly in order not to damage
prematurely the veneer on the front panel of the speaker. We
recommend this protection be kept in place to prevent acciden-
tal damage to the drivers. 1
Powerful drivers generate magnetic fields that can extend
beyond the boundaries of the speaker cabinet. We recommend
you keep magnetically sensitive articles (TV, computer screen,
computer discs, audio and video tapes, swipe cards...) at least
1.5 ft (50 cm) away from the speaker. Cabasse centre speakers
or the ones marked «TV» are not concerned with this, being
magnetically shielded.
POSITIONING SPEAKERS IN A ROOM
In addition to vertical position of the speakers themselves, their
location in the listening room, as well as the acoustical charac-
teristics of the room, are also very important. As it is impossible
to indicate a typical location of speaker systems without a few
tests, we suggest several general rules that are important to
apply in order to obtain the best listening results.
OPTIMAL POSITIONING FOR A 2.0 OR STEREO SYSTEM
For the ideal positioning of your speakers follow the diagram
2
on page 2. If «d» is the distance between the two spea-
kers, this distance must be equal to or greater than 5 ft (1.5 m).
Both speakers must be at equal distance from the listening
area which forms with them an isosceles triangle. «d1» and
«d2»distances must be identical, they should be equal to or
longer than «d».
The drivers must be directed towards the listening area.
The speakers should be located so that their diffusion follows
the longest dimension of the room.
Generally speaking it is better to avoid putting the speakers in
the corners of a room as this amplifies the low frequencies and
tends to enhance the room resonances. If possible it is better
to place the speakers at least 8 inches (20 cm) from the walls.
Moreover, in order to obtain a more accurate frequency res-
ponse, it is recommended to raise a compact speaker from 12
to 16 inches (30 to 40 cm) above the floor by placing them
on stands. The tweeters of the speakers must be roughly at
the height of the listener's ear when the listener is in sitting
position.
No solid object or piece of furniture should be placed between
the speakers and the listener. An effect of mask, even partial,
completely disturbs the sound reproduction as it attenuates
the high frequencies and also, in most cases, the midrange
frequencies.
Placing the speakers in niches is not recommended. Unless
designed for this application, bookshelf placement will alter
the frequency response of the speaker, especially in the low
frequencies. If a bookshelf location cannot be avoid, the spea-
ker should be set up to minimize various resonance, and the
visible part of the grille must be outside the niche.
OPTIMAL POSITIONING FOR A 2.1 OR STEREO WITH A
SUBWOOFER SYSTEM
For a stereo listening with 2 speakers or 2 satellites and
1 subwoofer, we recommend you to place the subwoofer in the
front listening area. The placement of the subwoofer against
a wall reinforces the low frequencies and limits the reflections
from 80 to 200 Hz. However to obtain the best results, it is
always necessary to carry out tests according to the acoustic of
the room.
OPTIMAL POSITIONING FOR A 5.1
OR HOME THEATRE SYSTEM
Setting up a multi-channel Audio-Video system requires great
care when positioning the specific AV speakers.
The centre speaker should be placed as close as possible to the
screen and where it sounds best from your listening spot while
offering the optimal picture/dialogues cohesion. Theoretically,
the screen should be located within a virtual triangle formed
by the acoustical centres of the main speakers and the centre
speaker. Practically speaking, this means that the principal
speaker should be placed above the screen if the main spea-
kers are below it, and below the screen if the main speakers
are above. The centre speaker should also, if possible, be set
slightly back from the others, so that it is located at the same
distance from the listener as the main speakers.
The rear speakers or surround should be placed against the
side walls, at listening height. They should not be positioned
far behind the listening zone.
The subwoofer should be placed in the front listening area,
its position against a wall reinforces the extreme low register
2
and limits the reflections between 80 and 200 Hz. However to
obtain the best result, it is always necessary to carry out tests
according to the acoustics of the room.
Your AV processor enables the adjustment in level and delay of
each of the 5/6/7 channels of your system. Fine-tuning is neces-
sary to obtain a perfect sound stage.
WALL MOUNT WITH THE OPTIONAL BALL BRACKET
1) Prepare all the necessary parts and tools: the ball bracket and
screws, plugs and drilling equipment suitable for the type of
wall and a spirit level.
2) Mount the bracket part with two holes on the back of the
loudspeaker, place the other part of the bracket on the wall
and use it as a drilling template, control the alignment and
drill the holes through the bracket. Place the inserts in the
holes.
3) Assemble both bracket parts, swivel the loudspeaker in the
right direction and tighten the bolt.
4) Connect the loudspeaker cable to the terminals. Ensure that
polarities are correct (see § Phase).
