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
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
