CAUTION: 
The Acoustimass
®
 6 and Acoustimass 10 speaker systems incorporate an auto-
matic protection circuit, which guards against most kinds of damage from electrical stress or 
overload. This circuit activates at high volume levels to reduce output, causing a slight 
decrease in volume. This is normal operation and indicates that power input may be exceed-
ing safe levels. Sustained listening at these levels is not recommended.
Adjusting the LFE level 
(low frequency effects)
The LFE level control on your powered Acoustimass module increases or decreases the rela-
tive level of low frequency effects on movie soundtracks. Use it to regulate the presence of 
these underlying deep bass sounds. Use the “test tones” feature in your digital surround 
sound receiver to match the volume levels for each of the cube speakers. Then use the LFE 
control on the Acoustimass module to match the volume of the LFE channel to the cube 
speaker channels.
Adjusting the bass/room compensation level
This feature will allow you to fine-tune your system after you have placed the Acoustimass 
module in your selected location. If the room sounds “thin” or lacks bass, turn the BASS con-
trol in a clockwise direction to increase the bass level of the module. If the room sounds 
“boomy” or has too much bass, turn the knob in a counter-clockwise rotation to reduce the 
bass level of the module. The factory or detent setting is appropriate for a majority of listening 
situations.
Setting your digital surround sound receiver 
Your Acoustimass 6 or Acoustimass 10 speakers are compatible with the output from digital 
surround receivers. Integrated Signal Processing assures full bass reproduction for all chan-
nels regardless of receiver settings. However, the following table suggests a set of recom-
mended receiver settings. The cube speaker arrays should be set to LARGE in the receiver's 
digital display menu. The LFE, or subwoofer, is set to ON. If applicable, the crossover value 
should be set to the lowest number possible, typically 80 Hz.
