ets, or speaker hangers to make this easy to accomplish.

Remember that they are designed to be installed verti- FIGURE 4 cally, with the tweeters aimed at the listeners' ears.

They can, however, be placed at virtually any height. This includes sitting directly on the floor, tilted up, as well as being mounted at ceiling height and tilted down. For certain installations, where the speaker is located above the listener’s ear level, the use of the S-150AC is a good alternative. See Figure 5. You may use three identical (S- 150AC) speakers for all three front main channels, if required. See Figure 6. Just remember that all three speakers should be at the same height or as close to the same height as possible.

Recommeded distance 2 ft. max.

If desired, a slight toe-in of the Left and Right speakers will improve the sound quality for listeners away from the cen- ter position, and can often improve imaging and overall sound quality by reducing the amount of side wall reflections reach- ing all listeners' ears. The S-150 Left and Right speakers give you a built-in toe-in through their angled front-baffle design.

A.Vertical Radiation Pattern (Narrow / Wide):

Your satellite speakers have a special feature developed for professional studio use. This feature allows you to vary the vertical radiation pattern to fit your system needs or your personal preference. The “Narrrow” position conforms with the THX Ultra standard.

After final aiming of the loudspeaker system has been completed, smooth high frequency coverage should be con- firmed throughout the listening area. When using the S-150thx near a mixing console or other reflective surface, it is preferable to set the S-150thx in its Narrow Mode. In the narrow mode the S-150thx will minimize floor, console and ceil- ing reflections, providing smoother horizontal on and off axis frequency response.

When multiple rows of seats need to be covered, or the monitoring area is larger than the Narrow Mode will cover, it is recommended that the S-150thx be used in its Wide Mode. This mode widens the vertical coverage angle, but also makes the speaker more susceptible to room boundary interference. Determining which mode best suites your moni- toring condition might require some experimentation or evaluation through careful listening tests.

B.Stacked / Single:

This switch allows you to stack more than one speaker to create a vertical array, either for higher output levels, or for use in very large rooms. Setting this switch to the “Stacked” position will bypass the Narrow/Wide function.

To do this, simply place one speaker on top of the other, with the tweeters aligned in a vertical stack. Then set the “stacked/single” switch to the “stacked” position.
