Internal Crossover Configurations

The crossover section of the Orion 8002 amplifier is continuously variable and extremely flexible. There are different crossover configurations possible allowing high-pass, low-pass, and band-pass configurations. The high-pass crossover incorporates the INTELLi Q feature. This circuit is designed to optimize the performance of Orion subwoofers in all types of enclosures.

When using Orion loudspeakers, minor deviations from the recommended frequency ranges can provide superior results depending on your speaker locations and your vehicle acoustics. Setting crossover frequencies higher than recommended will not cause damage and may provide superior sonic results depending on your system's performance goals. Refer to your loudspeaker owner's manual for assistance in choosing the proper crossover frequencies for your system.

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 10Hz 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 overexcursion.

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.
