plays the tones from the test CD and records the relative output
level of each test tone, using the sound-level meter, on the
provided measurement template.After all the tones are complete,
the template contains a response curve for the frequencies
below 100Hz.The user simply notes the frequency of the largest
bass peak, calculates the correct amount of attenuation, and
uses the “Q-Finder”to determine the width of the curve.These
three values are dialed into the Bass Optimization System
controls located on the speaker.The entire process takes less
than twenty minutes.
If your dealer does not stock the Bass Optimization System test
and measurement kit, you may purchase it directly from Infinity.

MAINTENANCE AND SERVICE
The enclosure and grille may be cleaned using a soft cloth to
remove fingerprints or to wipe off dust.
All wiring connections should be inspected and cleaned or
remade periodically.The frequency of maintenance depends on
the metals involved in the connections, atmospheric conditions,
and other factors, but once per year is the minimum.
If a problem occurs, make sure that all connections are properly
made and clean. In the event that your Infinity SW-12 subwoofer
