30Hz High-Pass used as a sub-sonic filter.

12dB/octave BP

•A sub-sonic filter is a high-pass filter that limits the input signal below a certain motion below that frequency. At very low frequencies a woofer has no output, just motion. If you try to drive this woofer at these lower frequencies, the woofer could self-destruct. Please refer to the crossover section of the manual or see your local Authorized Rockford Fosgate Dealer for more information.
