- Orion Owner manual Amplifier 7005

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 manufac-

turer's warranty.

Subwoofer High-Pass

This circuit is designed to optimize the performance of Orion subwoofers in all types of

enclosures.

WARNING! DO NOT set crossover frequencies lower than the speakers recommended

operating range. This can cause driver failure that is not covered by manufac-

turer's warranty.

Low-Pass Crossover

When the switch is to the right (OFF position), the low-pass crossover is bypassed. When the

switch is centered (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 variable

from 20Hz to 3kHz.

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 3kHz. The

high-pass crossover 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 excessive 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 Tunning the Crossover

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.
