Setting Up  
Before you begin  
Bose® Virtually Invisible® speaker technology allows you to enjoy lifelike home performances  
from the very latest surround-sound encoded movies, CDs, and television shows, without a  
room full of speakers. Each of the five cube speaker arrays, along with the Powered Acousti-  
mass® module, reproduces the full-spectrum of sound from multi-channel digital program-  
ming. Integrated Signal Processing assures full bass performance from all channels, at all  
listening levels, regardless of your receiver settings.  
Your stereo VCR, stereo television, or DVD player sends the encoded program material to the  
surround-sound receiver, which interprets and distributes the information to the Powered  
Acoustimass module. The module delivers the bass for all channels and sends appropriate  
sounds to each cube array. The sound mix varies with different program types: dialogue is  
usually sent to the center speaker, a visual soundstage is created by the left and right front  
speakers, and you feel in the center of the action because sounds and special effects are  
directed to the surround (rear) speakers. At any point in a surround-sound performance, you  
may hear sound from one, a few, or all of the speakers.  
To select surround-encoded program material, look for any of the terms Surround, Dolby  
Surround, the double-D symbol  
*, other digital formats, or the word sur-  
roundpreceding a TV broadcast. Your system is fully compatible with the latest home  
theater receivers. You can also enjoy a wide variety of stereo programming that is not sur-  
round-encoded with your Acoustimass 15 speakers.  
Unpack the carton  
Remove any staples from the opened carton flaps.  
Remove the brown inner carton containing the five cube speaker arrays.  
Gently roll the carton over onto its side and then onto its opening.  
Slowly lift the carton from around the Powered Acoustimass modules packing cushions.  
Do not detach the removable cables connected to the Powered Acoustimass module.  
If the speakers or the module appear damaged, do not use them. Repack everything in  
the original carton and contact your authorized Bose dealer immediately.  
Note: Now is a good time to record the serial number of these speakers on page 2 of this  
guide and on your warranty card. Please save all packing materials for possible future use.  
WARNING: The Powered Acoustimass module weighs 33 pounds (15 kg). Use good lifting  
practice to avoid injury.  
WARNING: To avoid danger of suffocation, keep the plastic bags that wrap these speakers  
out of the reach of children.

Setting Up  
Placing your speakers to achieve realistic home theater sound  
A suggested home theater layout that conforms to the guidelines described above is shown  
in Figure 2. You may want to place the speakers differently, to take advantage of the sound  
characteristics of different rooms.  
Note: The cube arrays are identical and can be used for any channel. All of the cube arrays  
are magnetically shielded to prevent interference with a television picture. Twist the cube  
arrays so the speakers create room-filling sound patterns.  
Note: Bose wall brackets and floor stands can extend your placement options. See Acces-  
sorieson page 13. Please follow wall bracket instructions carefully. Proper mounting will  
insure optimum performance from your system.  
Figure 2  
One suggested home theater  
layout  
Center cube speaker  
The center speaker localizes action and dialogue on your screen. Sound should seem to  
come from within the picture.  
Place the center cube array above, below, or on top of your television. If below, be sure  
that it is not supporting the weight of the television in any way.  
Keep the cube array as close to the vertical center of the screen as possible, for the most  
accurate dialogue reproduction.  
CAUTION: If you are placing the center cube array on top of the television, use the smaller  
of the two sets of four rubber feet provided. This will provide extra stability on surfaces such  
as marble or glass. Additional rubber feet are available, free, by calling the Bose® customer  
service numbers inside the back cover of this manual. Ask for Part Number 178321-04.

Setting Up  
Left and right front cube speakers  
The left and right front speakers create a sound image wider than the screen that seems  
natural to viewers sitting anywhere in the room. You can place them near a TV screen with no  
picture interference. See figure 2.  
Place the front cube arrays on either side of your TV, at least 6 feet (2 m), or as much as  
15 feet (5 m) apart.  
Surround cube speakers  
The surround, or rear, speakers add discrete sounds and special effects that expand the  
visual image, bringing the viewer into the center of the action. The surround speakers may  
carry dialog as well. The surround speakers should be positioned to allow the sound to reach  
the viewer from both sides, rather than from directly behind. See Figure 2.  
Place the speakers at ear height or higher, if possible  
Adjust the rear surround speakers to direct the sound to the front and back of the listener.  
®
Powered Acoustimass module  
Bose® Acoustimass speaker technology takes advantage of the fact that the source of pure  
bass sound is difficult to locate, so you can hide the Powered Acoustimass module conve-  
niently out of sight. Place the module at the same end of the room as the television monitor.  
You may hide the module behind or under furniture, but do not block the opening. Be sure  
there is at least 2 inches (5 cm) between the opening and any surface.  
If the opening faces the wall it increases the bass; if it faces away it decreases the bass.  
For the most bass response, place the opening 2 to 3 inches (5 to 8 cm) from a wall or  
corner.  
You may stand the Powered Acoustimass module vertically or horizontally (Figure 3).  
After selecting a place for the module, attach the larger set of four rubber feet to the  
bottom surface for additional stability.  
CAUTION: To prevent interference, keep the module at least 2 feet (.6 m) from the televi-  
sion.

Using Your Acoustimass 15 Speakers  
For realistic home theater sound  
LFE level control  
The LFE level control on your Powered Acoustimass module increases or decreases the  
relative level of low frequency effects on movie soundtracks. Use it to regulate the presence  
of these underlying deep bass sounds. You may find it unnecessary to adjust this control. The  
factory, or detent setting is appropriate for a majority of listening situations.  
Bass control  
The Bass control on your Powered Acoustimass module can help you customize your  
listening room. Turning the control to the right will add bass to the sound in rooms that might  
be characterized as too shrill. Turning down the control will brightenthe listening room. As  
with the LFE level control, you may find the factory setting to be completely appropriate for  
your listening room.  
Setting your Dolby Pro-Logic receiver  
For video applications, we recommend the surround-sound center mode setting of your  
receiver as WIDE (Figure 8). Instructions for this process vary, depending on the brand and  
model of receiver you are using. Follow your receiver owners guide for testing and adjusting  
the balance of each speaker.  
Figure 8

the center mode set to WIDE  
Setting your Dolby Digital receiver  
Your Acoustimass 15 speakers are fully compatible with the output from Dolby Digital receiv-  
ers. Integrated Signal Processing assures full bass reproduction for all channels regardless of  
receiver settings. However, the table below suggests a set of recommended receiver settings.  
The cube speakers are full-range, or LARGE speakers on the Digital screen menu. Turn the  
subwoofer and the LFE (low frequency effects) ON. Set the crossover to the lowest number  
possible, typically 80 Hz.

Note: The Acoustimass 15 speaker system incorporates an automatic 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 exceeding safe levels. Sustained  
listening at these levels is not recommended.

Using Your Acoustimass 15 Speakers  
Be sure to get the Dolby Digital signal  
To be sure that the Dolby Digital or other digital signal from your DVD player reaches your  
receiver, connect its digital sound output to the digital sound input on your receiver. You must  
use a coaxial cable, with RCA connectors on each end, or an optical (Toslink) cable that has  
unique, squarecable ends. See Figure 9. Be sure to connect the digital sound jacks; these  
are in addition to the traditional analog connections that carry the Dolby Pro-Logic signal.  
Many DVD players have a switch on the back which you must place in the digital position. If  
you cannot find such a switch, there may be an on screen menu where you must select digital  
audio.  
You must also be sure to select Dolby Digital at your receivers front panel or remote control.  
For example, when playing a movie on a DVD, you must select a video output, in this case  
DVD, and an audio output, Dolby Digital. You may also have to set up the digital signal using  
the receivers front panel or on-screen menu. Please consult your receiver owners manual for  
specific details.
