COMPONENT SYSTEM
This is a simple two-amplifier system using a 200
BIX Active Crossover for better control of the
frequencies applied to the speakers. The Low
Freq output is connected to the lows amplifier to
drive the subwoofer, and the High Freq output is
connected to the highs amplifier for driving the
midrange and highs speakers.
This allows you to carefully balance the higher and
midrange frequencies with the lows. In practice,
overlapping the crossover point slightly results in smooth transitions of sounds delivered to the speakers. For example, the cutoff frequency for lows
could be adjusted to 400 Hz. This would mean that all frequencies below 400 Hz would be passed to the lows amplifier at 100% power.
The attenuation (reduction in power) is 12 dB which is a reduction in power of about 90%. An octave is a doubling of frequency so that a 800 Hz
only about 10% of the power would go to the subwoofers. In this example, the high output would be adjusted to pass only frequencies above 300
Hz. This would give you about 100 Hz overlap. Then you could make slight adjustments to provide the sound that pleases you the most.
In a system utilizing a lows amplifier to drive the subwoofer, you would probably always want to use the summed mono mode as shown here. Use c
the built-in equalization or an Orion accessory equalizer depends on personal taste. If the bass is "boomy" whether or not you use an accessory
equalizer, the built-in equalization at the lows amplifier will improve overall performance.
