PLACEMENT FOR HOME THEATER REAR APPLICATIONS

 

(CONTINUED)

soundtrack to create desired effects. However, in a home with a single pair of front speakers, this 
surround effect will be lost, and jungle sounds may actually sound like they are emanating “from the 
middle of your head,” just like headphones! 

A single pair of CM6HDfx Loudspeakers, properly placed, can create a very convincing simulation of 
an array of surround speakers. Here are some recommended placement tips:

 

•    Place the surround speakers near a hard reflecting surface, as shown in 

Figure 2

.  

The reflections will help one pair of speakers to sound like several. If possible, try  
placing them near a corner (so that the adjoining walls will act as a powerful  
reflector) to create even more reflections, as shown in 

Figures 3 

and

 4.
