• If you place the surround speakers farther away from the listener, both the reflected
and the direct sound will dissipate, requiring even more power from the surround-
sound channels. If your sound system uses a small 5- or 10-watt surround amplifier for
the rear speakers, be sure to place the speakers within 5 to 8 feet of the
listening location.
• If you are using a larger 25- to 50-watt surround amplifier, you can mount the speakers
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 you like listening to music in surround modes (which emulate concert hall acoustics),
consider using more than two surround speakers to provide an extraordinary effect.
With Niles CM6HDfx loudspeakers, it is easy to add another pair without affecting the
decor of the room.
NOTE: FOR THIS APPLICATION, YOU WILL NEED TO USE A MORE POWERFUL AMPLIFIER THAN
THE ONE BUILT INTO A TYPICAL SURROUND-SOUND RECEIVER OR AMPLIFIER. NILES MAKES
A NUMBER OF SYSTEMS INTEGRATION AMPLIFIERS WITH PROPRIETARY FEATURES THAT
MAKE THEM UNIQUELY SUITED TO ENHANCE YOUR EXISTING SURROUND-SOUND SYSTEM.
CONSULT YOUR LOCAL NILES DEALER FOR MORE INFORMATION.
