Since the low-end frequencies of audio signals feature long wavelengths, they are almost non-directional to human ears.
The super-bass range does not create a stereo image. Therefore, a single subwoofer may be enough to produce a high-
quality super-bass sound.
• Placing the subwoofer too close to a CRT-type TV may impair the picture color or cause a buzzing noise. In this case,
place the subwoofer and TV at a separated position where these effects do not occur. This is not an issue with LCD and
plasma TVs.
• If the speaker volume is very loud, furniture or window glass may resonate and the subwoofer itself may vibrate. In this
case, lower the volume level. To limit resonance, use a thick curtain or similar cloth that tends to absorb sound vibrations
effectively. Also, changing the subwoofer position may be helpful.

Note
The placement shown in the
figure on the right is also
possible. However, if the
subwoofer system is placed
directly facing a wall, the bass
effect may suffer due to phase
cancellation caused by the
interference between the
direct and reflected sounds.
To prevent this from
happening, place the
subwoofer system at an angle.

There may be a case
that you cannot obtain
enough super-bass
sound from the
subwoofer due to
standing waves.
