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 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 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 speakers 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 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 necessary to obtain a perfect sound stage.
Turn off all the amplifiers before interconnecting them to the loudspeakers. In order to connect loudspeakers properly, it is most
important to keep in mind the following two factors: cable section and phase.
3.1 Cable section
To get the full sonic potential of Cabasse loudspeakers and avoid power losses, the cables
connecting the speakers to the power amplifier must have the lowest possible electrical
resistance. To help you in choosing the correct cable gauge, here is summary chart.
3.2 Phase
In order to maintain the phase relationship and frequency balance
of the loudspeaker system, both loudspeakers must be properly connected
to the power amplifier. When properly connected, the cones of the drivers of
both loudspeakers will move in the same direction when driven by identical
speakers will move in the same signals. If the cones move in opposite
directions, the resulting out of phase signals will create a perceptible power
loss, particularly in the low frequencies. The stereophonic message will also
be degraded. Amplifier and speaker manufacturers typically indicate
connection polarity in one of two ways: red and black or plus and minus. In
either case, always connect red or plus to red or plus and black or minus to
black or minus. Connections should be identical for both channels. To check
that the speakers are in correct phase, switch the system to mono while
music is being played. if the amplifier does net have a phase inversion switch, it will be necessary to change over the connections on
one only of the loudspeakers. If in correct phase, the image should be distinctly located between the loudspeakers with a slight loss
of bass and low midrange level. If the image is confused and not centrally located and there is a drastic loss of bass and low
midrange level, recheck your connections.
3.3 Bi amping
Some of our loudspeakers are fitted with two pairs of connectors to
carry out a passive bi-amplification or bi-wiring. Two straps connect the
connectors and allow the standard single amping use with one set of
speaker cables.
If you adopt a connection using only one cable, leave the straps in place
and use one of the two pairs of connectors.
To carry out a bi amplification (or bi-wiring), remove the two straps and
use two separate sets of cables with two amplifiers. They will be
respectively connected on the outputs of both amplifiers.
