Atlantic Technology ® The vast majority of the time, surround speakers are called upon to reproduce “environmental” sounds that are used as cues to tell you “where you are.” Dipoles are undoubtedly the best and most practical way to create such an involving and believable soundfield at home.

To optional second subwoofer Placement and Operation Speaker/room interactions have a huge impact on the sound of the system. Moving the speakers just a little bit can make a dramatic difference in what you hear. The compact design of System 170 provides you with maximum placement flexibility while creating a large, seamless, acoustically accurate soundfield for your home theater or music system.
Atlantic Technology ® Figure 3: Typical arrangement for speakers in a home theater. For best results, place the surround speakers within the shaded area. Note that the surround speakers are marked Left and Right. It is important that the speakers be placed correctly for proper imaging.
Models 171 LR, 173 C, and 174 SR The orientation of the 174 SRs is important to the proper generation of an involving and diffuse surround effect. To insure proper orientation, make sure that the RIGHT speaker is on the right side wall of the room, and the LEFT speaker is on the left side wall of the room, as you are seated facing the screen. The 174 SRs are marked RIGHT and LEFT on the back and have an arrow that should point towards the front of the room.
Atlantic Technology ® NOTE: There are several rubber pads supplied with your speakers. They are to be used as feet when the speakers sit on a shelf, or on stands. When you use the keyhole mounts, place these pads on the lower rear of the enclosure (remember, the enclosures are going to be mounted upside down), using a double thickness (one pad on top of another). This will keep the speaker level and stop it from vibrating on the wall.
