Where should I position a subwoofer in the room?
Subwoofer placement has a major impact on how the bass is perceived.
Low frequencies are strongly affected by the room’s size, shape and acoustics.
This means the same subwoofer can sound very different depending on where it is positioned.
Where should I start?
A good starting point is to position the subwoofer along the room’s front wall, near the stereo speakers or TV.
However, this is not always the position that gives the best bass reproduction.
Can I place the subwoofer in a corner?
Yes.
A subwoofer placed near a corner often produces stronger bass because the walls affect the sound.
This can be an advantage if you want more bass, but the position may also boost some frequencies too much.
The result can be uneven or boomy bass.
Does the subwoofer have to be between the speakers?
No.
Because subwoofers reproduce low frequencies, it is often harder to tell exactly where the sound comes from.
This gives greater freedom in placement.
However, if the crossover frequency is too high, the subwoofer’s location may become more audible.
What is the subwoofer crawl?
The subwoofer crawl is a method of finding a suitable position in the room.
Temporarily place the subwoofer at your normal listening position.
Play music with clear, even bass or a suitable test signal.
Move around the locations where the subwoofer could be placed.
Listen for where the bass sounds most even and controlled.
Then place the subwoofer there and check the result from the listening position.
The method provides a practical starting point, although the result may be affected by the room’s conditions.
Why does the bass disappear in some parts of the room?
Sound waves reflect off the walls, floor and ceiling.
At certain frequencies, the sound waves can reinforce or cancel each other.
This creates areas where the bass is strong and others where it is weak.
This is a common effect of room acoustics and does not necessarily mean there is anything wrong with the subwoofer.
Tip: Try several positions before compensating with higher volume or large EQ adjustments. The right position can make a major difference.
