height=\"212\" \/><\/p>\n<p>The installation suggestion is based on the information available from the Dolby Lab.\u00a0 With our experience, it should be fine-tuned for every listening room.\u00a0 The key is the positioning as the angle of the speaker position and the physical height of the speakers.<\/p>\n<p>To take an example, a room with wooden wall should be sounded very well.\u00a0 Further adjustment will be necessary for a brick wall.\u00a0 In order to build the best-fit system, you need to set your height and position of each speaker with the help of the AV system.\u00a0 Then, you have to compare the effects when sitting down at your seat by playing the same track until the most comfortable one.\u00a0 Moreover, the introduction of a pair of front-wide speakers may lead to overlapping of sound if the listening space being too small.<\/p>\n<p>With the additional speakers are installed under the ceiling, the ceiling height for the listening room should be considered.\u00a0 It is better to have 7.5 to 12 feet suggested by Dolby lab.\u00a0 In real practice, it is suggested to have 10 feet or above.<\/p>\n<p>Also, the 3-D plan is being shown
