Recommended Amplifier Power

For optimum performance, we recommend amplifiers with the following power ratings:

•For the OS 5.3Si loudspeaker, 5 to 100 W per channel

•For the OS 6.3Si loudspeaker, 5 to 125 W per channel

Ironically, most speakers 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 Operation on page 17 for more information about clipping distortion.

Placing THE LOUDSPEAKER for the Best Sound Quality

Traditionally, when using a pair of stereo loudspeakers, the listener will be positioned directly between the left and right loudspeakers to achieve optimum stereo sound. However, in some applications this is not possible, especially when a large area of coverage is required. It was for these types of applications that the OS “Si” loudspeaker was created. With its ultra-wide dispersion pattern, a single OS “Si” loudspeaker is able to project quality summed-stereo sound over a larger area. No matter where you are—you are always in the sweet spot. (See Figure 5 on the next page).
