English PLACEMENT 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 highquality super-bass sound. A or B or ( : subwoofer, : front speaker) 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. (Figures A and B ) Note There may be a case that you cannot obtain enough super-bass sound from the subwoofer due to standing waves. Note • 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. 2 En
