They should also be at least 0.5 meter from your TV set unless the speakers are magnetically shielded to avoid colourings on the TV screen. Note that most speakers are not shielded, even with complete surround sets only the Center speaker may be.
Depending on the specifics of your room acoustics and the type of speakers in use, you may find that imaging is improved by moving the
Using these guidelines, you’ll find that it takes some experimentation to find the correct location for the front speakers in your particular installa- tion. Don’t be afraid to move things around until the system sounds correct. Optimize your speak- ers so that audio transitions across the front of the room sound smooth.

A 6.1 surround speaker adds an additional center back surround speaker to the system, enabling you to enjoy the benefits of advanced surround modes such as Dolby Digital EX,
To step up to a 6.1 system, first place the speak- ers for a 5.1 system. The “sixth” speaker should ideally be placed at the center of the room’s rear wall, pointing directly toward the front center channel speaker.
Note: The
If you are only able to install a single surround back speaker at this time, you will not be able to run the full EzSet/EQ II
We recommend that you consider adding a sec- ond surround back speaker as soon as possible.
Rear surround speakers are required when a full
The additional Surround Back Left/Right speakers are placed at about 150 degrees on the circle, pointing inward, toward the listening area. The easiest way to visualize the placement of these speakers is to place the surround back left speak- er directly opposite the right front speaker and to place the surround back right speaker directly opposite the left front speaker.
Subwoofers produce largely nondirectional sound, so they may be placed almost anywhere in a room. Actual placement should be based on room size and shape and the type of subwoofer used. One method of finding the optimal location for a subwoofer is to begin by placing it in the front of the room, about 15cm from a wall, or near the front corner of the room. Another method is to temporarily place the subwoofer in the spot where you will normally sit, and then walk around the room until you find a spot where the subwoofer sounds best. Place the sub- woofer in that spot. You should also follow the instructions of the subwoofer’s manufacturer, or you may wish to experiment with the best loca- tion for a subwoofer in your listening room.
The AVR 745 is equipped for 7.2 operation, which means that you can increase the
•Although it is not mandatory, you will have the best performance when both subwoofers are identical in terms of driver size, amplifier power and cabinet design (e.g., ported or sealed).
•The optimal placement when two subwoofers are in use is to have them on the side walls of the room, to the immediate left and right of the listening position. If that positioning is not practical, a good alternative is to place the subwoofers in the front left and right corners of the room, or to place the subwoofers in any two corners of the room.
•Regardless of which subwoofer placement option is chosen, EzSet/EQ II will help to smooth room conditions to deliver the optimal bass response.
