[. . . ] If the 4200e SR's are used as back surrounds in a 6. 1 or 7. 1 channel system, they should be installed with the Right speaker placed over the listener's left shoulder and the Left speaker placed over the listener's right shoulder; these back surrounds should be placed approximately 150 degrees from the screen on the back wall. About one-third of the way out from the corners in most rooms is a good starting point. If you are using a THX Ultra 2 certified controller/receiver, you should place the back surround speakers approximately 1 to 2 feet (. 3, . 6m) apart in the center of the back wall. The special circuitry in the processor will help to create a believable and effective surround field using this placement. Please read the electronics manual to learn more about this placement option. Home Theater Remember that the primary goal of a good home theater is not to make you believe that you are in a movie theater. It's to make you believe you're in the movie. For a home theater system, place the LR speakers on either side of the television. The three front channel speakers (LR and C) are magnetically shielded so they will not interfere with your television picture. The left and right front speakers should be far enough apart (6 to 10 feet, 2-3 meters, is usually best) that you get a good stereo "image" when they are playing alone, but not so far apart that the sound seems to be disembodied from the TV, distracting you from the picture. When using a center channel speaker, a wider separation of the left and right front speakers is usually possible. You may chose to "toe" the LR speakers in, aiming them approximately at the prime listening position. This can be particularly useful if the front LR speakers are fairly far apart. IMPORTANT NOTE Try to keep the LR and C tweeters at approximately the same height and aimed at ear level when seated. This is because we've designed the alignment of the drivers on the front panel to limit the vertical spread of the mid and high frequencies, thereby reducing the floor and ceiling reflections that adversely affect sound quality. If the speakers are too high or too low however, you will miss a significant portion of the upper middle and high range elements of the sound. Remove ½" (13mm) of insulation from each wire end. Twist the stranded wire together, keeping the two ends separate. Place the appropriate wire through the postholes in the connectors. These holes are revealed when you loosen the connector's capscrew. Screw down the capscrew tightly, but be careful not to over tighten it. Check the tightness of the capscrews 24 hours after hookup and occasionally after that, as they can loosen over time. The goal is to reproduce the most accurate musical timbre and the most convincing natural sound. Additionally, a well set-up stereo pair of speakers will create excellent imaging and a cohesive representation of the soundstage. Placement in the room and your listening position has an enormous impact on the ultimate sound you will achieve from your system. [. . . ] Use the ¼" x 20 insert on the bottom of each speaker to couple the stand directly to the speaker via a ¼" x 20 bolt. This connection is recommended not only for better sound but for safety (especially if you have little ones running around) The recommended stand height is approximately 30". See Figure 5. On the Wall (4200e SR only) To mount your speakers on a wall, we have supplied metal key-hole brackets attached to the back of the cabinet. These speakers are heavy and care must be used when hanging them. [. . . ]
