Checking your speaker system

As you begin listening to your Acoustimass 5 Series III speaker system, the following test will
help you determine that it is working properly:

A. Turn the balance control on your receiver or amplifier all the way to the left. If you have

connected the cube arrays properly, you will hear the music from the left cube array, but
not the right one. You may notice a very faint sound issuing from the right cube array,
which is normal.

B. Now, turn the balance control all the way to the right. If your cube arrays are connected

properly, this time you will hear music only from the right one. You may also detect a very
faint sound from the other cube array.

C. Return the balance control to the center position. Play a musical selection with deep

bass. Now turn the balance control all the way to the left and listen, and then turn the
balance all the way to the right and listen. If the system is connected properly, the center
position should exhibit the same or greater bass response than either the left-only or
right-only positions. If it exhibits less, check to make sure that your components are
connected as described on pages 6 and 7.

D. Return the balance control to the center position.

If your system does not appear to be working properly, refer to the Troubleshooting section
on page 11.

Positioning your speaker system to get the best sound

Your Acoustimass 5 Series III speaker system may be used in a variety of ways. Here are
some guidelines.

Cube considerations

A. In average-sized listening rooms, the best stereo effects result when the left and right

cube arrays are spaced 6 to 12 feet apart (1.8 – 3.6 m). However, you can still achieve
excellent results with separation as little as 3 feet (1 m) or as great as 15 feet (4.5 m).

B. The cube arrays are magnetically shielded for use with video systems and may be placed

near your television without adversely affecting picture quality. However, the Acoustimass
module is not shielded and should be kept at least 2 feet (.6 m) from a television.

C. Though there is no “correct” position for the cube arrays or the angle between them, the

most lifelike effect will be achieved by providing a balance of direct and reflected sound.
Experiment with the positions of the cubes for the results you prefer. Figure 6 shows
some typical cube arrangements.

D. You may use the cube arrays with both cubes facing forward. This eliminates the benefits

of direct and reflected sound, but may be appropriate for very small listening areas.
