4. o blurry dialogue Apart from colouring the sound also the perspective of the sound will deteriorate Reflections in the room can roughly be compared to the reflections that yield ghost pictures on a TV screen A loudspeaker that is placed near a wall ceiling or floor will amplify lower frequencies in a sometimes not desirable way since it may lead to an indistinct sound recreation This amplification becomes even more obvious if the loudspeaker is placed near a corner Thus for a sound as clear as possible the loudspeaker should be placed at least 30 cm about 12 inch away from the wall Some constructions are made to be placed closed to a wall Be aware that furniture may vibrate and thus create bad sound at loud bass Quadratic rooms or rooms where the length is exactly twice as long as the width should be avoided since they may create unwanted resonance The placement of the subwoofer in the room dramatically affects the overall frequency response and sound level of the system At low frequencies the effect of the room is strong Even a slight change in the subwoofer s location can make a significant difference in the frequency balance Patience and methodical experimentation is needed to find an optimal placement The placement affects the phase difference between the main loudspeakers and the subwoofer One basic rule is to place the subwoofer together with or near the front system especially important if the front l
