THE ACTIVE SUBWOOFER MAGNAT QUANTUM 7230A
This subwoofer has been adapted to provide the best visual and acoustic match to the MAGNAT
QUANTUM 720 range of loudspeakers. However, it goes without saying that it may be combined with
other loudspeakers.
When connecting your loudspeaker, please make sure that everything has been switched off. Furthermore,
make sure that all loudspeaker cables are connected to the proper poles, i.e. the positive pole for the
output is connected to the positive pole for the input and the negative pole with the negative pole. Please
also refer to your receiver's/amplifier's and loudspeakers' instructions.
POSITIONING
The frequency range reproduced by the subwoofer cannot be pinpointed by the human ear. That's why
positioning generally doesn't present any problems. However, it is preferable to place the speaker
close to the front loudspeaker in front of the listening position. You should also make sure that the
distance from the sides and from the rear to items and walls is at least 20 centimetres as otherwise
bass reproduction may be impaired.
