set up
There are several ways of positioning a subwoofer in the room. As the loudspeaker provides only deep tones (sometimes) under quite
heavy sound pressure, the quality of the sound is influenced by the acoustics of the room. It may, therefore, be a good idea to try out
different positions. Please note:
that the amount of bass is increased when the subwoofer is positioned close to a wall and reduced when the distance to the wall is
increased. A corner will increase the amount of bass
that the subwoofer’s sound reproduction can be changed by alternating between bass reflex and sealed chamber – see the special
section about this
that the position of the subwoofer vis-à-vis the stereo system’s other loudspeakers is important for the sound. If possible, you
should place the subwoofer between the main speakers (front speakers) and at the same distance from the listener as the main
speakers
if the subwoofer is placed on a solid base, e.g. a wooden floor, we recommend that you use the rubber feet or protectors under the
spikes. If the subwoofer is placed on a soft base, e.g. a carpet, we recommend that you use spikes.
that if the subwoofer is used in bass reflex mode, you must leave enough free space under the unit for air to be escape freely from
the reflex port
the better your system, the better the subwoofer will sound
that multiple subwoofers in the same system is usually better than a single one
that good cables will improve the sound
never turn the volume up to a level where the sound is no longer clear
SA subwoofers can be used to supplement centre channel speakers and speakers in a stereo system, etc.
remove the front grille for the best possible sound

choice of bass reflex / sealed chamber
the subwoofer is delivered bass reflex configuration but can easily be changed to sealed chamber.
Turn the cabinet around so the underside faces up. You may wish to use the protective frame from the
packaging as a base. Remove the 4 screws shown on the illustration to the right. Turn the bottom
plate 180°. Replace the 4 screws. The reflex port is now sealed and the cabinet will act as a sealed
chamber.
It is a matter of taste which option you choose. Here are a couple of pointers though.
Choose sealed chamber if: Choose bass reflex if:
