The most common damping materials used are Dacron and Polyfill. Reclaimed fiber underlay has been discovered to be an excellent
substitute especially when glued directly to the walls of the enclosure. Fiberglass may be used, but please limit usage to sealed
enclosures only. When used in vented/bandpass enclosures, fiberglass fibers escaping through the port may be hazardous to your
health.

Rating the power handling of subwoofers is not a difficult task. However, understanding power ratings is often
confusing. Many times the Maximum Power Ratings are viewed as the RMS power handling of the driver, when in
actuality Maximum is generally the break point of the driver. This has lead Crossfire to come up with a system to
rating the power necessary to drive our subwoofers. Please read the following cautiously before choosing your
amplifier.
Nominal power handling
-Nominal power handling is the power rating given by Crossfire at which the subwoofer will experience
minimal mechanical degradation over time when using a recommended enclosure. In other words, this is the
recommended power to be used per woofer to assure long life.
Maximum power handling (PE)
-Maximum power handling is the power rating given by Crossfire at which the subwoofer could experience a
high amount of mechanical degradation that may lead to possible failure over time when using a
recommended enclosure. In other words, do not exceed this power level for extended periods of time.
Dynamic power handling
-Dynamic power handling is the power rating given by Crossfire for peak transients and short bursts.
Continuous playing at or above this level will cause mechanical failure and/or thermal failure. In other
words, this power level should never be attained with the exceptions of approved SPL competition vehicles.
This could possibly void your warranty.
