• The installation location selected should have a sturdy
floor surface. Mounting the speaker on a long-pile
carpet should be avoided, since the carpet may touch
the driver’s diaphram, causing distorted sound.
• Please install this unit away from the antenna cable of
the tuner, as noise can be caused with installation
close to the antenna cable. In such a case, use this
unit 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 this unit.

limit for the subwoofer (
50 Hz, 60 Hz, 70 Hz, 80 Hz,
100 Hz, 120 Hz, 160 Hz, 200 Hz
