01 Dec 09 Home Theater Design: Optimum Speaker Placement
The standard theater-style course is a screen at one end of the room, with a center speaker, a speaker on each side of the screen, two surround speakers provide left and right, and sometimes a speaker providing surround rear. If your rooms are arranged in this way, chances are good that you call your home theater and speaker placement is fairly straightforward for you. The ideal placement has the front speakers at the same height from theSoil, usually either slightly above or slightly below the display and the surround speakers at least 60cm above the heads of the spectators.
The front center speaker should ideally in the same position as the screen, the left and right speakers should be placed approximately 25 degrees to the left and right of the direction of the viewer's face, and about the same distance from the spectators who Surround – left and right surround speakers should be about 90 degrees to the left and rightthis direction, and again, about the same distance from the spectators, and the surround, as the name implies, should be directly behind the audience. A subwoofer can be used when theoretically be placed anywhere in the room.
For many people, and I agree with it, is the design of your home, so it does not allow for a comfortable rooms decorated in this way. Still, unless you are very happy, chances are that the area contains your home theaterAmenities Double your living room, and you will not want it to be dominated by a screen. You may not want to call your home theater as such. To solve this problem, you have to draw on a scale of chart to your room. Add your screen determines the placement of the drawing, together with the seating arrangements (your sofas and chairs), and determine where people sit when they watch movies and look in what direction it is.
The next thing you need to do isto draw a line from each viewer directly to the screen, the direction in which shows every spectator faces. Then you draw a line angle 25 degrees to the line that you are being pulled from the left of the viewer, for every spectator, until it meets the wall. If the speaker is placed anywhere along this line, then it is at the proper angle for the appropriate viewer. You need to identify a point along the wall to reach pretty much the situation in the vicinity where these lines the wall. This is usuallysomewhere near the middle of the collection of lines. You can then determine the optimum home theater placement for your front left.
You must now do the same, but angle the lines 25 degrees to the right of the direction in which the viewer's face. With these lines you can identify the optimum home theater placement for the front left speaker.
Repeat for lines angled 90 degrees to the left, 90 degrees to the right, and 180 degrees (Continuation of the line from spectator-screen), but in the opposite direction. With these lines you can identify the optimum home theater placement for the left surround speaker, the right surround speakers and back surround speakers.
Ideally, the front left and right speakers at the same distance should be placed by any viewer, should like the left and right surround speakers. This will not usually be possible to achieve, so it should be approximated. Much more important are theSpeaker placement angles for each viewer, which ideally no more than about 15 degrees away from the optimum position. Optimum home theater speaker placement depends on minimizing the angle error for each viewer.
Your subwoofer can theoretically be placed anywhere in space, because the ear is not easy to determine the direction of low frequencies. However, you may find that positioning the subwoofer in different parts of the room change the soundsfrom the subwoofer, some frequencies can be strengthened, while others may be reduced, especially if the subwoofer is placed near a wall or corner of the room. It is suggested that you experiment with the placement of the subwoofer until you find a position that suits you.
Some other considerations may influence the position to ask which one the speaker. You will not want that your speakers in a position where they have a path that went through a regular obstacle, such as too close to a door. Even if you are not magnetically shielded from the front speakers, they should not be marketed to old to close a cathode ray tube (-style) TV, because it is the purity of the color on the screen lead is compromised. This does not apply to LCD or plasma television. With this approach, you can successfully place your speakers so that you can be proud of your home theater in your living room and at the same time!
Always remember that the idea behind home> Theater is set up on your system, so you can enjoy movies in full. Some people lose sight of that goal. Whatever you do with your home theater design, do not fall into the trap of over-analyzing your results. Start enjoying these movies!
