iCub: 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.
