Setting Up
Before you begin 
We appreciate your choice of the Bose 
® 
 Acoustimass 
® 
 15 series II or Acoustimass 16 home 
entertainment speaker system.
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. The cube speaker arrays, along with the powered Acoustimass mod-
ule, reproduce the full-spectrum of sound from multi-channel digital programming. 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 speaker array. The sound mix varies with different program types: dia-
logue is usually sent to the center cube speaker array, a visual soundstage is created by the 
left and right front cube speaker arrays, and you feel as if you are in the center of the action 
because sounds and special effects are directed to the rear cube speaker arrays. At any point 
in a surround-sound performance, you may hear sound from one, a few, or all of the cube 
speaker arrays. 
To select surround-encoded program material, look for the terms Surround, Dolby Surround, 
the double-D symbol  
3 
, Dolby Digital  
1 
, other digital formats, or the word “sur-
round” preceding a TV broadcast. Your system is compatible with home theater receivers. 
You can also enjoy a wide variety of stereo programming that is not surround-encoded. 
Unpacking the carton 
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. 
Note:  
This product is not to be powered by any DC-to-AC inverters that may be found in 
automobiles, recreational vehicles, boats, ships, or other similar situations. 
Carefully unpack the carton contents (Figure 1):
1. Remove the brown inner carton containing the cube speaker arrays.
2. Gently roll the carton over onto its side. 
3. Slowly pull the Acoustimass module from the carton.
4. Stand the module up.
If the cube speaker arrays or the module appear damaged, do not use them. Repack every-
thing in the original carton and contact your authorized Bose dealer immediately. Or, to con-
tact Bose directly, see the list of offices and phone numbers enclosed with your system.  
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.

Carton contents 
Placing your speakers to achieve realistic home theater sound 
A suggested home theater layout is shown in Figure 2. You may want to place the speakers 
differently to take advantage of the sound characteristics of different rooms. Here are some 
suggested guidelines for placing your speaker system:
•The cube speaker arrays are identical and can be used for any channel.
•All cube speaker arrays are magnetically shielded to prevent interference with a TV picture.
•The top and bottom sections of the cube speaker arrays can be rotated to create 
room-filling sound patterns (Figure 3). 
•Bose 
® 
 wall brackets and floor stands can extend your placement options. See “Accesso-
ries” on page 17. Please follow wall bracket instructions carefully. Proper mounting will 
ensure optimum performance and safety from your system. 
Note:  
The Acoustimass 15 Series II may be upgraded by adding a center rear cube speaker 
array. See “Upgrading your Acoustimass 15 Series II speaker system” on page 12.

CAUTION:  
To prevent interference, keep the Acoustimass module at least 2 feet (.6m) from 
your TV set. 
Figure 3 
Sound patterns 
Front center cube speaker array 
The front center cube speaker array localizes action and dialogue on your screen. Sound 
should seem to come from within the picture. 
•Place the front center cube speaker 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 front cube speaker array as close to the vertical center of the screen as possible, 
for the most accurate dialogue reproduction.  
CAUTION:  
Choose a stable and level surface for your cube speaker arrays. Vibration can 
cause them to move, particularly on smooth surfaces like marble, glass, or highly polished 
wood. If you are placing the center cube speaker array on top of your television, use the set 
of four rubber feet provided. You may obtain additional rubber feet (part number 178321-04), 
free of charge, by contacting Bose 
® 
 Customer Service. See the list of phone numbers 
included with your system.

Setting Up 
Front left and right cube speaker arrays 
The front left and right cube speaker arrays create a sound image wider than the screen that 
seems natural to viewers sitting anywhere in the room. You can place the cube speaker arrays 
near a TV screen with no picture interference. Place the front cube speaker arrays on either 
side of your TV, at least 6 feet (2m), or as much as 15 feet (5m) apart (see Figure 2).  
Rear cube speaker arrays 
The rear, or surround cube speaker arrays add discrete sounds and special effects that 
expand the visual image, bringing the viewer into the center of the action. The rear cube 
speaker arrays may carry dialogue as well. 
•Position the left and right rear cube speaker arrays to allow the sound to reach the viewer 
from both sides, rather than from directly behind (see Figure 2).
•Place the rear cube speaker arrays at ear height (when seated) or higher, if possible.
•Rotate the top and bottom sections of the rear cube speaker arrays to direct the sound to 
the front and back of the listener.
• 
If you have a center rear cube speaker array 
 (Acoustimass 16 system or upgraded Acousti-
mass 15 Series II system), place it so that it is centered between the rear left and right cube 
speaker arrays (see Figure 2). 
Powered Acoustimass

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 furniture, but do not block the opening. Be sure there is at 
least 2 inches (5 cm) between any surface and the front opening or the grille on the bottom. 
•If the opening faces the wall it increases the bass; if it faces away it decreases the bass.  
CAUTION:  
To prevent interference, keep the module at least 2 feet (.6m) from your TV set.

Note: Placing the module horizontally, or on 
its side, may reduce ventilation, inhibiting its 
ability to play at full output for extended 
periods of time.

Setting Up 
Connecting the Acoustimass 
® 
 module to the receiver  
The 20-foot (6.1m) system input cable connects the module to your surround receiver (see 
Figure 6). The system input cable has a multi-pin connector on one end and several wire pairs 
on the other. The wire pairs of the cable may be separated or “unzipped” as much as needed 
to comfortably reach the surround receiver connections. Each wire pair is marked on the 
cable jacket with  
RIGHT 
,  
LEFT, CENTER, RIGHT SURROUND, LEFT SURROUND, or 
CENTER SURROUND to indicate where each wire connects to the receiver.
CAUTION: Before making any connections turn off your receiver and unplug it from the AC 
(mains) outlet. Not doing so may result in damage to your system.
CAUTION: Do not connect the powered Acoustimass module directly to your TV unless it 
provides surround decoding circuitry and amplified outputs for all channels.
1. Insert the multi-pin connector on the system input cable into the input jack on the Acous-
timass module. Tighten the two thumbscrews to assure a secure connection.
2. Connect each wire pair on the other end of the system input cable to your surround 
receiver. Carefully match the polarity of the connections (+ to + and – to –).
•Attach each marked wire (+) to the appropriate + terminal.
•Attach each plain wire (–) to the appropriate – terminal. 
Note: The RCA plug of the system input cable comes with a cover installed. Remove 
this cover for connection to the LFE/SUBWOOFER OUT jack. If your receiver has no 
LFE/SUBWOOFER OUT jack, leave the plug cover in place.
3. If applicable, connect the RCA plug marked LFE on the system input cable to the 
LFE/SUBWOOFER OUT jack on your surround receiver.
CAUTION: Do not allow exposed wires to brush against each other; this could damage your 
receiver.
