Thank you very much for choosing Cabasse speakers.
Please read carefully these instructions before setting up your speakers.
UNPACKING 1
After opening the top carton flaps, remove the grille. Then
fold the carton flaps right back and invert the carton contents.
Lift the carton clear of the contents and remove the inner pac-
kaging from the speakers. We suggest you to retain the packing
for future use.
POSITIONING
Speakers positioning
Our speakers have been designed to function in a vertical posi-
tion. Under these conditions, the polar response is most uni-
2
form .
The majority of our models are delivered with a set of decou-
3
pling spikes or cones , these accessories are to be screwed in
the inserts under the cabinets. These accessories ensure the
stability of the speaker while limiting resonance coming from
certain types of grounds like wood floors.
Speakers are delivered with a front grille to protect drivers. It
is possible to use them without this front grille, but we recom-
mend this protection to be kept on to prevent accidental dama-
4
ge to the drivers .
Powerful drivers generate magnetic fields that can extend
beyond the boundaries of the speaker cabinet. We recom-
mend 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 cha-
racteristics of the room, are also very important. As it is impos-
sible to indicate a typical location of speaker systems without
a few tests, we suggest several general rules that are impor-
tant 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 diagram.
If «d» is the distance between the two speakers, this distance
must be higher than 5 ft (1.5 m) and the two speakers must be
at equal distance from the listening area which forms with
them an equilateral triangle.
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 same height of the listener's ear when the listener is in sit-
ting position.
No solid object or piece of furniture should be placed between
the speakers and the listener. An effect of mask, even partial dis-
turbs completely the sound reproduction as it attenuates the
high frequencies and also, in most cases, the midrange fre-
quencies.
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 fre-
quencies. If a bookshelf location cannot be avoid, the speaker
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 sub-
woofer, 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 limit 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
5
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. Theo-
retically, 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 prin-
cipal speaker should be placed above the screen if the main
