Niles Audio IW770FX, IW650FX manual More reflections

INSTALLATION CONSIDERATIONS (CONTINUED)

■Place the surround loudspeakers on a rear wall directly behind the listening position. If possible, try placing the loudspeakers nearer to the corners, as shown in Figure 2 and 3. Set each BIPOLE/DIPOLE switch to DIPOLE for reflected sound. Moreover, the adjoining walls will act as powerful reflectors to create even

more reflections.

■If you place the surround loudspeakers farther away from the listener, the surround sound will dissipate, requiring even more power from the surround-sound channels. If your sound system uses a small (less than 50 watts per channel) surround amplifier for the rear loudspeakers, be sure to place the loudspeakers within 5 to 8 feet of the listening location.

■If you are using a larger (more than 50 watts per channel) surround amplifier, you can mount the loudspeakers 10 to 15 feet away from the listening location and still achieve reasonably high volume levels. In large or unusually-shaped rooms, this might be the only way to achieve a good effect.

■If your home theater system is capable of reproducing Dolby Surround EX® consider using a second pair of StageFront FX loudspeakers (on the side walls) for an additional rear surround effect, as shown in Figure 4. Ideally, the side loudspeakers should be placed in-line with the listening position with the BIPOLE/DIPOLE controls set to DIPOLE. For a more focused surround effect, set the BIPOLE/DIPOLE controls to BIPOLE.
