Recommended distances from a single wall to the front baffle of free-standing loudspeakers.
Correct (green), acceptable (orange) and not recommended (red).
lower the low frequency cut-off the further away the loudspeaker must be placed from the wall in order to
avoid this phenomenon.
Distances to the ceiling and other walls may be shorter than the distance to the wall behind a loudspeaker.
Reflections from these surfaces may be important and should also be considered.
Subwoofer Placement
Subwoofers can make life much easier in producing high quality low frequency energy. When a subwoofer
is used, the loudspeakers can be placed more freely, thereby allowing more flexibility in finding a good
location in the room for the reproduction of low frequencies.
A subwoofer should be placed close to a wall, preferably closer than 0.6 meters (2 ft.) from a wall. This
placement eliminates most possible cancellation sources and the subwoofer response remains flat and
well loaded.
