Optimizing Subwoofer location in a room
Special techniques for find-
ing the best location for a
subwoofer
Here are two useful techniques for placing a subwoofer in a room.
The first is unique in that it does not involve moving the subwoofer
around the room:
Place the subwoofer where your main listening position will be,
connected to your system. Play some music through the system, and
then walk around the room, stopping to listening to the sound quality
of the bass in potential room locations for the subwoofer.
The location where you hear the best combination of smooth re-
sponse, exciting deep bass, with impact and sock, and the least "boomi-
ness" is likely to be the best place to locate the subwoofer.
Move the subwoofer to that location, and continue your listening
tests from the main listening position. If the sound quality is good,
leave the subwoofer where it is. If it is not, continue experimenting as
above.
The other technique is to use a sound level meter and a series of
low-frequency test tones (100 Hz and below), such as those found on
a test disc. Move the subwoofer to each possible location in the room,
taking measurements at the listening position for each location. Mea-
sure the sound level for each frequency and plot it on a sheet of graph
paper. The location that has the smoothest overall response is the
best location for the subwoofer.
