.........................................................6 Specifications......................................................................6 Installation The Subwoofer is a virtually omnidirectional speaker, so it can be installed in almost any location. For example, the Subwoofer can be installed next to the component system (consisting of an amplifier, tuner, cassette deck, etc.), or in a corner of the room, etc.. The subwoofer’s deep-bass reproduction charac- teristics are richest when the subwoofer is installed in a corner or near a wall. Since the low-bass component in music is usu- ally monaural, only one subwoofer is necessary to obtain a sufficient stereo effect when used in combination with a ste- reo music system. CAUTION To assure ventilation, observe the following points when installing the unit. •Leave a distance of more than 10 cm between the Subwoofer back and the surrounding wall(s). Use special care not to cover the heat sink with a cur- tain, etc. when installing. •Do not place the equipment onto a bed, a sofa, a carpet, or similar. Sucked-in dust can cause fire. •Be sure to install the Subwoofer vertically.

The howling phenomenon may also occur due to cross interference with a cassette deck, compact disc player, or Laserdisc player, althoug...
