Placement of the
subwoofer
Why use 2
Subwoofer
Cables
Finally
The placement of the subwoofer in the room
dramatically affects the overall frequency response
and sound pressure 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 loudspeaker also propagate bass
frequencies) as this will minimize the risk of phase
eliminations in the room.
The benefits of having two subwoofers instead of
one:
- The sound pressure level will be higher.
- Less dips and standing waves and a better
frequency response in the room (and in
sweet spot).
- The need of power is less, to reach the
same SPL as with one subwoofer.
Try to keep them as short as possible. By its
electrical parameters, a long conductor will have a
bigger influence on the sound than a short one. It
may also work as an antenna and thus receive
various signals that may become a constant noise in
an active subwoofer.
Make sure that all connections are clean and not
oxidized. All connections should be mechanically
stable, both power, signal and loudspeaker cables.
Signal cables should be separated from other
cables.
Please remember that good sound is a matter of
taste, so you have to experiment to obtain your
favourite one.
We wish you best of luck!
