• Sure, you will have a center-channel speaker, but don’t use this as an excuse to put the left and right speakers 15 feet apart. To provide the best combination of stereo spread, imaging precision, and coherence with the picture, a good rule of thumb is to position the left and right front speakers so that the distance between the two speakers is equal to or preferably a little less than the distance from each speaker to the listener. For instance, if your speakers are 7 feet apart, a distance of 8 to 9 feet from each speaker to the listener is excellent. You should avoid setting the speakers farther apart than the distance from each speaker to the listening position.
• I recommend that you place the speakers at least 7 feet apart for any listening position that will be 10 to 12 feet from the screen of a one-piece television and no more than 10 feet apart. For a front-projection setup, you should position them no more than a foot or so to the left and right sides of the screen.
• Many people sit too far from their TVs and speakers. For a 7-to-9-foot speaker spacing, I recommend that you sit at least 8 to 12 feet from the speakers.
If you sit too close, the sound from each of the speakers’ drivers may not gel properly into a coherent whole. If you sit too far away, you’ll hear too much of the room. If you’re really unlucky, you’ll hear an amorphous blob of sound rather than a well-defined soundstage.
