Positioning
The loudspeakers have been engineered to deliver the most faithful sound reproduction, whether they are used for
music or home cinema. In order to enhance their performance, to guarantee a high quality of listening, sound image
and tone balance, it is important to note the following basic rules.
The listening area must be located at the summit of an equilateral triangle whose two other points of insertion are
determined by the position of each speaker. Nevertheless it is possible to modify these distances to find an ideal
compromise according to the particular disposition of the room (fig.A).
Each loudspeaker must be placed at the same height and on the same floor plan. The tweeter should be at the
same height as the listener’s ear, when the listener is in their usual listening area (fig.B).
Avoid placing the loudspeakers too close to the room’s corners or walls. This will induce some unwanted room
resonance and artificially increase bass response. On the contrary, if the bass level proves to be insufficient, it is
possible to move the speakers closer to the walls to adjust the bass level (fig.C).
Optimization
For perfectionist people, we will give an optimum positioning rule: If A is the determined distance between the floor
and the middle of the two woofers (X), C is the distance between X and the side or back wall, then the distance B is
found with the
equation B2 = AC.

It is imperative to respect the connector polarity of both the loudspeaker and amplifier. The positive terminal
“+” must be connected to the corresponding (matching) amplifier’s terminal and the negative terminal “-“ to the
negative terminal (fig.E). Stereo image, soundstaging and bass perception would be seriously compromised if these
conditions were not respected.

their best performance. They must get adapted to the tem-perature and humidity conditions of their environment.
This breaking-in period depends on the encountered conditions and can last several weeks. In order to shorten
this period, we advise you to let your loudspeakers operate for about twenty hours at medium level, playing standard
musical programmes, but with a large amount of bass.
Once the components of the loud-speakers are completely stabilized, it is possible to enjoy the real performance of
your loudspeakers.

User instructions
The sound rendition of the loudspeaker strongly depends upon the listening room acoustics, the place of the
loudspeakers and the listening area. These factors can be modified in order to correct or enhance a desired effect.
Should the soundstage be imprecise or not centred, try to move the loudspeakers closer to each other.
Harsh or aggressive sound means that your listening room is probably too reflective. Try to use any absorbing
materials (such as tapestries, sofa, wall coverings, curtains…) combined with reflective materials to absorb or diffuse
resonances.
Should the sound be “flat” or muffled, there are too many absorbing materials in the listening room. The sound
appears to be closed-in, with a narrow stereophonic image. Try to find a better compromise between absorbing and
reflective materials within your listening room.
Generally the wall to the rear of the speakers should be made up of reflective materials so that the sound image
H[KLELWVVDWLVI\LQJYROXPHDQGZLGWK2QWKHFRQWUDU\WKHZDOORQWKHUHDURIWKHOLVWHQHUVKRXOGEHDEVRUELQJLQRUGHU
to avoid reflections damaging the perception of the stereo soundstage. These reflections may limit the impression
of depth of the sound image. Furniture, such as bookshelves should ideally be placed along the side walls in order
to diffuse sound waves and to prevent some frequencies from being amplified, especially in vocal range (it removes
“flutter echo”).

Safe practice
The 3 position mode selector has been developed to suppress any short-circuit risk or connection error when two

configuration, we strongly recommend to carefully follow mode selector connection and setting instructions.
Turn off any amplifiers connected to SR 1000 Be during each mode selector operation!
Bipolar mode (5.1)
Set the right and left surround loudspeakers back selector in Bipolar position. Always connect the amplifier to right
DQGOHIW65%HLQSXW➊(fig.L).
Note: in bipolar mode, the loudspeakers work together towards the front and the back of the listening area in order
to cover it in a smooth and consistent manner.
Note: input ➋is always inoperative when the selector is set in the Bipolar position.

Note: the side channel is always connected to input ➊for both left end right loudspeakers and the center channel
always to input ➋. That approach permits switching the selector from Bi mode to Twin mode without wiring
modification.
Note: Twin mode allows back and side surround information to be carried simultaneously to a single surround
loudspeaker, dividing it in two parts beaming towards the front and the back of the listening area.
Note: surround side channel information will be carried to the front while center channel information will be carried
towards the back of the listening area thanks to the two sets of separated connectors.

Accessories
Floorstanding loud-speaker systems include four decoupling spikes and four butyl cone and could be screwed, if
necessary, into the four metal inserts situated on the base of the loudspeaker. These spikes ensure a better stability
for floorstanding speakers, particularly if the floor is not perfectly flat and smooth. This stability improves clarity in
bass and midrange by decoupling the system from the floor and thus reducing floor-born resonances.This required
stability allows the energy delivered by the woofer cone to be integrally converted into sound. The enclosed spikes
are adjustable in height. After having adjusted the height of the spikes, don’t forget to lock them with the locknut.

Bookshelf speakers can be placed on an optional stand specially developed for them.

Don’t underestimate the importance of the cable: make sure you chose the appropriate section and length. Let your
retailer advise you.

It is advised that you use the foam bung for both loudspeakers. Insert the foam bung into the port tube until it is
flush with the front surface.
About amplifiers
Contrary to what one might think, it is not a too powerful amplifier that might damage a loudspeaker, but rather a
lack of power. Actually if the output level of the amplifier is too high it will saturate and distort which will irremediably
damage the tweeter.
The power handling and frequency response of the loudspeakers is good enough to highlight the qualities or weak
points of the amplifiers they are combined with. Let your retailer help you make the right choice, matching your
personal taste and budget.
