After unpacking your S10, keep all packing materials for future transport. In the
event that you need to ship your subwoofer, only the original, purpose-designed
shipping carton is acceptable. Any other method of shipping this product runs a
significant risk of damage to the subwoofer — damage that would not be covered
by the warranty. (If you lose your packaging and need to ship your subwoofer,
replacement packaging can be purchased from Wisdom Audio.)
CAUTION:
Do not attempt to lift your S10 by yourself. Unpacking this subwoofer is a two-
person job. It is unwise for a single person to attempt doing so.
Do not attempt to lift your S10 while bending or twisting from the waist. Use your
legs for lifting, not your back.
Always stand as straight as possible and keep the S10 close to your body to reduce
strain on your back.
Subwoofer Placement
Subwoofers offer somewhat greater flexibility in placement, since the frequencies
they reproduce are not readily localizable by the human ear. This is due to the fact
that the wavelengths they reproduce are more than ten feet (3 meters) long, but our
ears are located only about 6-7 inches (17 cm) apart. Thus these extremely long
waves do not contribute meaningfully to the imaging that the main speakers create.
However, this fact does not mean that the placement of the subwoofers has no
effect on the sound quality in the room…far from it. The subwoofers are the
most
likely to suffer from the response irregularities introduced by the room itself,
operating as they do below approximately 80 Hz in most systems.
Recent research into the behavior of rooms as a function of speaker placement has
concluded that — if you have the freedom to do so — there are significant
advantages to placing several smaller subwoofers around the room, rather than
relying on a single large woofer. Moreover, the optimum placement is usually
centered on each of the four walls, or deep in the corners of the room. If you have
the luxury of doing so, this simple placement strategy can reduce the size of the
room’s response irregularities from 20 decibels down to perhaps as little as 6-8
decibels—a tremendous improvement.
Reducing the room’s inherent problems to this degree provides a huge advantage.
It allows the SC-2/3 System Controllers to put its considerable abilities to work on
perfecting your system’s response, rather than on trying to perform major corrective
surgery.
