SW Four Overview
The AudioSource SW Four represents the state of the art in self-powered subwoofer systems. The
highly efficient ported enclosure houses a rugged twelve inch, reinforced driver, plus a powerful one hundred
fifty watt amplifier, all teamed up with an integral stereo crossover network. This precision matched
combination ensures that the SW Four will deliver the best sound possible, under even the most demanding
conditions. The advanced, down-firing design disperses the sound evenly throughout the listening area.
Crossover frequency, as well as input level, are both variable over a wide range, allowing the SW Four to
complement a variety of applications. Line level and hi level inputs and outputs are provided for fast and
easy connection to virtually any system. The three-way Auto Power and the Phase Reverse functions
complete the list of professional features offered by the SW Four.
A Few Words About Subwoofers
Subwoofers are designed to introduce extended bass response to your system, beyond what traditional
speakers alone can offer. The subwoofer is used in conjunction with, not in place of, your existing speakers.
It is not necessary to have a pair of subwoofers. The low frequency sounds created by the subwoofer will
radiate equally into your listening area. A single subwoofer can dramatically enhance a simple TV, a stereo
system, or a fiill fledged Home Theater system
The advent of digital recording has increased the amount of low bass information that can be accurately
recorded. A subwoofer can reproduce this low bass information. On the Home Theater front, many video
tapes and movies are recorded featuring low frequency information well below the "musical" range of
traditional loudspeakers. However, this information can be vital to the impact, ambience, and believability
of a scene. Again, a subwoofer can faithfully restore those elements to your Home Theater listening
experience.
Some System Guidelines
In setting up your subwoofer, keep in mind a few rules to assure yourself of the best performance.
Placement of the subwoofer is not crucial. Locating the subwoofer near a wall or in a comer will increase
the bass response of the speaker. The sound waves coming from the SW Four are long, and need room to
propagate. A subwoofer placed too close to the listener will not sound as full as one placed a few feet further
away. The level of the SW Four is best set while listening to all the speakers. By itself, the sound of the SW
Four is hard to distinguish.
The cabinet of the SW Four is designed to blend in with most decors. It can also be easily hidden under
an end table or coffee table, behind a sofa, near the comer, etc... If you decide to place anything directly on
the SW Four, use great caution as the speaker cabinet will vibrate and items placed on top may shake loose
or fall.
