Incorporated in the high-pass crossover, INTELLi Q maximizes the performance of a subwoofer. The high-pass subsonic filter removes unwanted bass output from the woofer, increasing the output of a subwoofer by as much as 3 dB due to the increased mechanical power handling. Depending on the enclosure, using INTELLi Q can increase the low frequency response by an additional 10dB!!! The boost level is identified by the corner markings. Acceptable boost levels are determined by the type of enclosure used and the woofer’s excursion capability. Listed below are recommended boost levels for different enclosure designs.
