Phase Switch
In many car audio systems placement of the subwoofers can cause them to be out of phase with the rest of the system. This may cause poor subwoofer performance due to varying arrival times. To eliminate this the Rubicon501/ incorporates a 0 to 180 phase switch. By playing low frequency music and experimenting with the subwoofer phasing better sound quality and bass imaging may be obtained.

24 dB/Octave Low Pass
12 dB/Octave High Pass
For initial crossover setup, try setting the low pass filter to approximately 60 Hz, and the high
pass filter on the rest of the sytem to approximately 100 Hz. Change the crossover points to accom-
modate a good mix- ture of frequency
response, power handling, and per- sonal preference.
CROSSOVER & PHASE ADJUSTMENTS
The RUBICON amplifiers incorporate an on-board staggered electronic cross- over. No external electronic crossover is necessary. The low pass portion of the crossover can be set independently of the rest of the system.
In many car audio installations, there is a tendency for a “midbass boom.” Because of their interior dimensions, most cars will resonate or ring at these midbass frequencies. If we design the system so there is reduced output in this region, the final response is very smooth and natural sounding. The Rubicon501/ has an always on low pass crossover that is independently variable from 40 to 160 Hz at 24 dB/Octave.
