more “surround sound” effect. However, as you move the loudspeaker farther away from the listener, both the reflected and the direct sound will dissipate, requiring more power from your surround sound amplifier channels. If the surround sound system you are using has a small five or ten watt amplifier for the rear loudspeak- ers, stay within five to eight feet of the lis- tening location. If you are using a 25 to 50 watt amplifier you can mount the loud- speakers 10 to 15 feet away from the lis- tening location and still achieve reason- ably high volume levels.

In large or unusually shaped rooms this might be the only way to achieve a good effect. If you like to listen to music surround modes which emulate concert hall acoustics, more than two surround loudspeakers will prove extraordinarily effective (See Figure 6). With Niles DS8.3 and DS8.5 loudspeakers it is easy to add another pair without affecting the decor of the room. However, you will need to use a much more powerful ampli- fier than that which is built into a typical surround sound receiver or amplifier.

Niles makes a number of Systems Integration Amplifiers with proprietary fea- tures that make them uniquely suited to

The Boundary Effect

Corners can affect the bass response of the loudspeaker powerfully! This is called the boundary effect. You will emphasize particular bass frequencies and cancel out other bass frequencies when you place loudspeakers close to the wall/ceiling boundary or a corner wall boundary. This can make the loudspeaker sound exces- sively boomy and inaccurate to some lis- teners, while to others it just seems like more bass sound. A good rule of thumb is if you always listen to your current pair of loudspeakers with the bass turned up, you’ll enjoy corner placement. If you keep your tone controls at neutral, try to keep the loudspeakers at least two or three feet from the boundaries of the room.
