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. U.S. residents can visit our Web site at www.infinitysystems.com or call 1.516.674.4INF.

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 ever needs service, contact your local Infinity dealer or Infinity directly at 1.516.674.4INF (USA only) or www.infinitysystems.com for a service center near you.

The cabinet design of the SW-12 is engineered with a focus on reducing vibration and resonance. Constructed from durable MDF (Medium Density Fiberboard), the enclosure is both solid and aesthetically pleasing, enabling it to blend with various decors without compromising sound quality. Additionally, the subwoofer includes adjustable feet for fine-tuning placement, which is essential for optimal sound performance.

In summary, the Infinity SW-12 subwoofer combines advanced technology, impressive power, and user-friendly features to create a compelling audio experience.
