Yamaha YST-SW216 Owner's Manual

2

 ( 

: subwoofer, 

: front speaker)

One subwoofer will have a good effect on your audio 
system, however, the use of two subwoofers is 
recommended to obtain more effect.

If using one subwoofer, it is recommended to place it on 
the outside of either the right or the left front speaker. (See 

fig. 

.) If using two subwoofers, it is recommended to 

place them on the outside of each front speaker. (See 

fig.

 .) The placement shown in fig.

 is also possible, 

however, if the subwoofer system is placed directly facing 
the wall, the bass effect may lessen because the sound from 
it and the sound reflected by the wall may cancel out each 
other. To prevent this from happening, face the subwoofer 

system at an angle as in fig.

 or 

.

There may be a case that you cannot obtain enough super-
bass sounds from the subwoofer when listening in the 
center of the room. This is because “standing waves” have 
been developed between two parallel walls and they cancel 
the bass sounds. 

In such a case, face the subwoofer obliquely to the wall. It 
also may be necessary to break up the parallel surfaces by 
placing bookshelves etc. along the walls.

Put the provided non-skid pads at the four corners on the 
bottom of the subwoofer to prevent the subwoofer from 
moving by vibrations etc.
