Positioning the center speaker 

 

(NX-C270)

 

Place the center speaker precisely between the 
front speakers, facing directly forward. You can 
place the center speaker on top of a TV (if the top 
of the TV is flat), on the floor beneath the TV, or in 
an entertainment center. Be sure to place the 
speaker in a stable location.

When placing the speaker on top of a TV rack, etc., 
to prevent the speaker from falling, attach the 
provided fasteners at two points on the bottom of 
the speaker and on top of the TV, as illustrated 
below.

 

Cautions:

 

• Do not place the center speaker on a TV that has a top 

surface area smaller than the speaker bottom. 
Otherwise, the speaker may fall and cause injury.

• Do not place the center speaker on a TV that has a 

slanted or inclined top.

• Do not touch the adhesive surface of a fastener after 

you peel off the seal, as this will weaken the adhesive 
strength of the fastener.

• Thoroughly wipe to clean the surface where the 

fastener is to be applied. Note that adhesive strength 
will be weakened if the surface is dirty, oily or wet. 
Weakened adhesive may cause the center speaker to 
fall.

 

Positioning the subwoofer 

 

(SW-P270)

 

It is recommended to place it on the outside of 
either the right or the left front speaker. (See fig.

 

 A

 

.) 

The placement shown in fig. 

 

B

 

 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. 

 

A.

Note:

 

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.

 

Non-skid pads:

 

 Place the included non-skid 

pads at the four corners of the bottom of the 
subwoofer to prevent the subwoofer from sliding 
due to vibration or minor impact.

Peel off 
the 
seal.
