[. . . ] The Bose® Acoustimass® 15 Home Theater Speaker System Owner's Guide October 22, 2001 AM194452_06_V. pdf Introduction Thank you We appreciate your choice of the Bose® Acoustimass® 15 home theater speaker system. With these Virtually Invisible® speakers you will surround yourself with realistic sound, with a minimal amount of equipment. Your system features new third generation Acoustimass cube speaker arrays, a product of the continuous research and development at Bose Corporation. These cube speakers deliver more lifelike sound and better overall performance, yet are smaller than their predecessors. [. . . ] 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. 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.

AM194452_06_V. pdf October 22, 2001 5 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. · 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. · 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 conveniently 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. [. . . ] Be sure to select a source at the receiver (video, CD, DVD, tuner). For digital sound, be sure a coaxial or optical cable connects the digital output of the DVD player with the digital input on your receiver. Be sure the audio source selected is correct. For example: select DVD audio on your receiver and player for DVD sound. [. . . ]
