WARNING! DO NOT set crossover frequencies lower than the speakers recommended operating range. This can cause driver failure that is not covered by the man- ufacturer's warranty.

Low-Pass Crossover

When the switch is to the left (OFF position), the low-pass crossover is bypassed. When the switch is in the middle (12 position), the low-pass crossover is active with a 2nd order (12dB per octave) slope. When the switch is to the right (24 position), the low-pass crossover is active with a 4th order (24dB per octave) slope. The low-pass crossover is continuously vari- able from 30Hz to 250Hz.

High-Pass Crossover

When the switch is to the left (OFF position), the high-pass crossover is bypassed. When the switch is to the right (ON position), the high-pass crossover is active with a 2nd order (12dB per octave) slope. The high-pass crossover is continuously variable from 20Hz to 150Hz and is optimized for use as a subsonic filter. Additionally, boost can be added at the high-pass crossover frequency for improved bass output while still protecting the woofer from exces- sive excursion. The INTELLi Q adjustment allows up to 10 dB of boost at the selected crossover frequency.

WARNING! Exercise caution when setting INTELLi Q. Maximum boost can potentially cause woofer damage due to over-excursion.

Fine Tuning the Crossovers

The low-pass and high-pass crossover sections are each marked at four frequency points for ease of system adjustment. The low-pass crossover section is marked at 30Hz, 50Hz, 150Hz, and 250Hz. The high-pass crossover section is marked at 20Hz, 33Hz, 90Hz and 150Hz. Specific crossover points can be chosen based on the recommended operational bandwidth of your speakers.

Adjusting INTELLi Q

Incorporated in the high-pass crossover, INTELLi Q maximizes the performance of a sub- woofer. 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 fre- quency response by an additional 10dB! The type of enclosure used and the woofer's excur- sion capability determine acceptable boost levels. Listed below are recommended boost lev- els for different enclosure designs.
