SPEAKER ADJUSTMENTS

Pivoting Woofer

The Symphony S623

SSTR

, S621sstr and SRS1 mocels have a pivoting woofer assem-

bly. These pivoting drivers allow you to direct sound toward or away from the 

listening area, depending on how the speakers are being used:
• Pivoting the woofer towards the listening position will maximize the speaker’s

clarity and definition.

• If you’re using the speakers as surround channel speakers in a home theater,

you can create a more diffuse, spacious surround effect by aiming the woofers

towards a wall or window,

away from the listeners.

To pivot the woofer, apply

pressure on the outer edge

of the tweeter support brack-

et, as shown in 

Figure 7. Do

not touch or apply pressure

to the woofer cone.

Apply pressure on the outer

edge of the tweeter support

bracket,

as shown in 

Figure 8. Do not touch or

apply pressure to the woofer

cone.

Tweeter Level Control

The S623

SSTR

has a tweeter level 

control switch (see 

Figure 8) that lets

you boost or cut the tweeter’s level by

3dB. This allows you to adjust the

speaker’s brightness to better match

your listening room or personal taste.
Once you have installed the speakers,

listen to a variety of music that you

are familiar with. If the music all

tends to sound too bright or dull, use

the Tweeter Level Control to compensate. If some recordings sound dull and some

sound bright the speaker is accurately reproducing differences in the recordings,

and you should leave the control in the middle (0dB) position.
