Positioning
Contrary to conventional high fidelity loudspeakers which
have to be placed at a reasonable distance from walls and
the listening area corners, we advise you to place your Cub
3
subwoofer in a corner of the listening area. If the subwoofer is
placed against only one wall or too far from the walls, the very
large wavelength of the bass delivered by the subwoofer will
excite the resonance of the listening room in an unpredictable
way. Frequency response linearity will then be damaged and
therefore the sound rendition will be affected (lack of depth,
“boomy sound”, poor bass, difficult or impossible coupling with
the other used loudspeakers).
If you put the Cub
3
in a corner, the resonant frequencies
of the room will be more linear and predictable. In such a
configuration, you will not only benefit from an optimum
perception of the bass frequency range but the bass level will
also be increased by 6dB.
If a particular disposition of the room does not allow to place
the subwoofer in a corner, we recommend you to try different
configurations until you find the best possible disposition.
Generally, the subwoofer should be placed along the front wall
of the listening room.
Because the bass frequency waves are omni-directional, the
sound dispersion will not be affected if a piece of furniture or an
object is placed between the subwoofer and the listening area.
