8 T10S SUBWOOFER MANUAL [ENGLISH]
3.3 WALLS/DISTANCE TO WALLS
Generally, every wall relatively close to the subwoofer enhances its sound pressure level
by about 6 dB. However, the effect of the subwoofer sitting on the floor has already been
considered in the design of the T10S. For instance, placing the subwoofer in a corner of
a room will make it about 12 dB louder [6 dB per wall A and wall B]. While the subwoofer
efficiency for loudness will be increased, it is likely that this will result in less precision
of the au dio reproduction.
But do keep in mind starting with the subwoofer between the main monitors at the
same distance as the main listening position. Once the system is up and running expe-
riment with other positions to see where the best performance is found.
Another problem related to the geometry of the room concerns are “standing waves” or
“room modes”. These are sound waves being reciprocated between reflecting objects,
so they “stand” [don’t seem to move] in between these objects. The speaker continues
to produce new waves that combines its force with the first wave[s]: a vicious circle
that results in hot spots in the room, where certain bass frequencies are too loud and,
conversely, quiet spots, where the same frequencies are barely audible.
Please note, that this hot spot/quiet spot pattern changes with frequency and is
different in every room.
3.4 FINDING THE OPTIMUM POSITION
Give it a try! The most important tool for finding the best position for your subwoofer
are your ears.
