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, repro duce t he full- spectrum of sou nd fr om mult i-cha nnel dig ital pr ogrammi ng. Int egrated
Signal Processing assures full bass performance from all channels at all listening levels,
regardless of your receiver settings.
Your stereo VCR, st er eo televi sion, or DVD player s ends the en coded pr og ram materi al 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 s pecial ef fects a re di rect ed to the r ear cu be speaker arrays. At an y 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
ing a TV broadcast. Your system is compatible with home theater receivers. You can also
enjoy a wide variety of stereo programming that is not su rround-encoded.

Placing your speakers to achieve realistic home th eater 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 floo r stands can extend your placement options. See “Accessories” 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.

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
your system.

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 speake r arrays on
either side of your TV, at least 6 feet (2m), or as much as 15 feet (5m) apart (see
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
• 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.

Connecting the Acoustimass module to power
Note: Bose® recommends using a quality surge suppressor on all electronics equipment. Volt-
age variations and spikes can damage electronic components in any system. A quality suppressor can eliminate the vast majority of failures attributed to surges and may be purchased
at an electronics store.
After you have checked al l s yst em co nnec tion s, p lug t he po wer cord of the powered Acousti mass module into an AC (mains) receptacle. Your Acoustimass speaker system will turn on
and off automatically as it receives a signal from your surround receiver.
Upgrading your Acoustimass 15 Series II speaker system
Your Acoustimass 15 Series II speaker system can be upgraded to provide you with 6.1 or
6 channel surround sound.
The 6.1 upgrade kit contains one black (PC 029661) or white (PC 029662) cube speaker
array, a 50-foot connecting cable, and complete connection instructions.
To purchase the 6.1 upgrade kit, contact your local authorized Bose retailer or call Bose
directly. See the list of Bose offices and phone numbers enclosed with your system. When
ordering, you will need to know the serial number of your Acoustimass module.
12
For realistic home theater sound
CAUTION: The Acoustimass® 15 Series II and Acoustimass 16 speaker systems incorporate
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.
Adjusting the LFE level
The LFE (low-frequency effects) level control on your powered Acoustimass module
increases o r decr eases the r el ative l evel of low- fr equency ef fects on movi e sound track s. Use
it to regulate the presence of these underlying deep bass sounds. Use the “test tones” fea
ture 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 sel ect ed l oca ti on. If t h e r o o m so und s “t hin ” or lac ks bass , tu rn 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 modu le. The fact ory or deten t setting is appr opriate for a majority of listen ing
situations.
