[. . . ] When moving the subwoofer, avoid touching the bottom surface, since the speaker unit is located there. ⷠOrient the subwoofer's front face pointing toward the listening position. ⷠThe subwoofer plays back the bass in monaural, making use of the fact that the human ear is not very sensitive to the direction of low-pitched sound. Because of this, the subwoofer can be installed almost anywhere. If it is installed too far away, however, the sound from the other speakers may become unnatural. The degree of bass effect can be adjusted by moving the unit farther from or closer to the wall. Labels located on the rear of each speaker indicate whether they are designed for front or surround use. ⷠSpeakers installed to the right and left should be separated by about 1. They should be installed at equal distances from the television, and at equal heights from the floor. ⷠOptional speaker stands can be purchased to facilitate optimal mounting of the surround speakers at or slightly above the listener's ear height.

(Avoid cooking tables and other locations where the unit would be exposed to heat, steam and soot. ) · Keep the subwoofer away from devices such as cassette decks which are sensitive to magnetic fields. ⷠDo not place cups, glasses, or other containers with fluids on top of the units, since the units may be damaged if the liquid spills. ⷠThe installation location selected should have a sturdy floor surface. Mounting the subwoofer on a long-pile carpet should be avoided, since the carpet may touch the driver's diaphram, causing distorted sound. ⷠPlease install the subwoofer away from the antenna cable of the receiver, as noise can be caused with installation close to the antenna cable. In such a case, use the subwoofer at a position away from the antenna and the antenna cable, or when playback of extra bass is not required, switch off the power for the subwoofer. ⷠThe front grilles on front/center/surround speakers cannot be removed.
