Page: 6Practice of sound / Installation and placement tipsThis chapter contains common information onloudspeaker placement and installation.This is general rules, so there are exceptions ofsome rulesIn which room doyou achieve the bestsound?No matter how good the equipment is, in the wronglistening environment it will inevitably sound bad.There are some basic rules concerning a properloudspeaker installation:Reflections Carpets, curtains and soft furniture absorb midrange and high frequency sound, and this ispreferable. Big empty area, on the contrary, reflectsit and produces hard reflections that may lead toblurry dialogue. Apart from colouring the sound,also the perspective of the sound will deteriorate.Reflections in the room can roughly be compared tothe reflections that yield ghost pictures on a TVscreen.Amplification of bassfrequenciesA loudspeaker that is placed near a wall, ceiling orfloor will amplify lower frequencies in a sometimesnot desirable way (since it may lead to an indistinctsound recreation). This amplification becomes evenmore obvious if the loudspeaker is placed near acorner. Thus, for a sound as clear as possible, theloudspeaker should be placed at least 30 cm (about12 inch) away from the wallSome constructions are made to be placed closed toa wall.Furniture Be aware that furniture may vibrate and thus createbad sound at loud bass.Room dimension Quadratic rooms or rooms where the length isexactly twice as long as the width should beavoided, since they may create unwantedresonance.Placement of thesubwooferThe placement of the subwoofer in the roomdramatically affects the overall frequency responseand sound level of the system. At low frequenciesthe effect of the room is strong. Even a slightchange in the subwoofer's location can make asignificant difference in the frequency balance.Patience and methodical experimentation is neededto find an optimal placement. The placementaffects the phase difference between the mainloudspeakers and the subwoofer.One basic rule is to place the subwoofer togetherwith or near the front system (especially importantif the front loudspeaker also propagate bassfrequencies) as this will minimize the risk of phaseeliminations in the room.
