Cub: user manual
Placement
While a traditional speaker should be away from walls and
corners in the listening environment, we recommend that you
place iCub in a corner
(fig I, J).
If iCub is installed against a lone wall, or too distant from the
walls, the very important long wavelengths will negatively excite
the resonances of the listening room. The frequency response
will not be linear and the bass quality will be adversely affected
(lack of bass, hollow sound, muddy bass, perceived low output,
difficult or impossible cross-checking with other loudspeakers, etc).
Installing iCub in a corner, the room resonance will be affected
in a more linear and predictable fashion. Not only will the
perception of bass be optimal, but this positioning will permit
an increase of bass output to +6dB
(fig. K)
. If you cannot place
the subwoofer in a corner or have other restrictions on its
placement, attempt different locations in the room until you
find the best compromise.
Generally speaking, the best location for the subwoofer is in the
front of the listening room.
As the bass frequency band is not directional, bass is not in
principle adversely affected in case there is an object or a piece
of furniture between the subwoofer and the listening position.
Magnetic disturbance
The iCub generates a magnetic leak that may interfere with
other sensitive household appliances. It is strongly advised not
to place the iCub closer than 50cm (20") to your TV screen.
Frame geometry as well as colours can be severely distorted
by a magnetic field if the loudspeaker is placed to close to the
cathode ray tube.
Generally, every sensitive elements (audio tapes, video tapes,
magnetic data storages, projector and CRTS overhead-
projector) should not be placed too close to non-shielded
loudspeakers.
