For optimum performance, we recommend an amplifier with a power rating of: five

(5)to one hundred (100) watts per channel for the 0S 5.5 loudspeaker; five (5) to one hundred twenty five (125) watts per channel for the OS 6.5 loudspeaker; five

(5)to one hundred fifty (150) watts per channel for the OS 7.5 loudspeaker. Ironically, most loudspeakers are not damaged by large amplifiers but by small amplifiers. If you are playing at high volume, a small amplifier will run out of power very quickly. When an amplifier runs out of power it creates damaging “clipping” distortion. A large amplifier will play at the same volume without distorting. See the section “Operation” for more information about clipping distortion.

Placing Loudspeakers for the Best Sound Quality

An OS loudspeaker’s dispersion pattern is very broad. This allows good sound quality over an extremely large listening area. However, if a single pair is positioned to provide coverage of a very large room or patio, you will have “hot spots” of loud sound when you are near the loudspeakers. The best way to avoid hot spots for a large space is to use several pairs of loudspeakers evenly spaced throughout the room. A good rule of thumb is to install a pair of loudspeakers for every 200 to 400 square feet of listening area. Your local Niles dealer is a good source for advice on loudspeaker placement for your particular installation.
