Recommendations for use
The behaviour of the loudspeakers depends on the acoustics of the listening room, on the correct positioning of the
loudspeakers within the room, and on the position of the listener.
It is possible to tweak each of these parameters to obtain or improve a desired effect.
Stereo perception is imprecise and poorly centred: try moving the loudspeakers closer together and/or have them
facing the listening point:
The sound is harsh, aggressive: the acoustics of your listening room are probably too reverberant. Consider using
sound-absorbing materials (carpets, upholstered furniture, tapestries, curtains, etc.) and sound-reflecting materials
(furniture) to absorb or diffuse resonance.
The sound is “flat”, strangled: there are too many sound-absorbing materials in the room, the sound is soaked up, it
has no relief. Look for the best compromise between sound-absorbing and sound-reflecting materials in your room.
In general, aim to have a reflective wall behind the loudspeakers for the sound to develop correctly. The wall behind
the listening area, on the other hand, should ideally be sound-absorbing to avoid rear reflections “contaminating”
the stereo image.
Furniture can be strategically placed near the side walls of the room to diffuse sound waves and ensure certain
frequency ranges are not excited, particularly in the midrange (suppression of flutter echoes).
Spikes
Sopra floorstanding loudspeakers are equipped with decoupling spikes built into the glass base. These spikes give
the floorstanding loudspeakers very good stability, particularly on uneven floors. The height of the spikes supplied
can be adjusted to ensure the 4 spikes rest evenly on the floor to prevent any wobbling. Once the height of the spikes
has been adjusted correctly, lock them in place using the locking nuts (fig. F). Four spike pads are also supplied to
protect soft floors such as parquet, etc. (fig. G).
Fastening Sopra N°1 loudspeaker to the stand
We recommend fastening the Sopra N°1 loudspeaker to the stand using the four screws supplied with the stand
(fig. H).
Foam Bung for Bass Tuning (Sopra N°1)
This foam bung allows you to make some fine adjustments to the bass performance of your loudspeakers. The Sopra
N°1 loudspeaker has been designed to reproduce deep bass in an even manner for a "free space" position. If you
position your loudspeakers close to a wall, bass frequencies are further enhanced. Similarly, some rooms have an
acoustic that exaggerates low bass. The foam bung allows you to reduce the amount of energy from the port tube
to reduce bass levels and improve damping in such situations. It is advised that you use the foam bung for both
loudspeakers. To do so, insert the foam bung into the port tube as shown in Figure I.
