Car audio crossovers are a class of electronic filters designed for use in audio applications such as hi-fi. A commonly used dynamic speaker driver is incapable of covering the entire audio spectrum on its own.
The crossovers split the audio signal into separate frequency bands that can be handled by individual speaker drivers optimized for those frequency bands. Let’s take a closer look at Kenwood’s KE-600 Crossover, KPX-F801 Crossover, and Kenwood KPX-L101 Crossover.
Kenwood KE-600 Crossover
One of Kenwood’s most advanced signal processors, the KE-600 is a 6-way electronic crossover with built-in parametric equalizer and a DC-to-DC power supply for high-voltage, low-noise outputs.
It has input selection, phase shifting, variable level controls, and the following outputs: subwoofer, low pass, low cut, high cut, and high pass. It’s a great component for multi-amp setups and is available for around $370.
Characteristics
● DC to DC converter.
● High frequency output.
● Input selector.
● Different phase switches.
● Subwoofer output from 30 Hz to 800 Hz (low pass).
● 6-way multi-amp configuration.
● Variable level controls.
Kenwood KPX-F801 Crossover
Kenwood KPX-F801 Crossover is a 3-way passive crossover network. It is available for around $75.
Characteristics
● Guard circuit that protects against excessive tweeter inputs.
● Special capacitors and inductors for audio purposes.
● Phase inverter switch for midrange and tweeter.
Kenwood KPX-L101 Crossover
Kenwood KPX-L101 Crossover is a low pass passive crossover network. It is available for $50.
Characteristics
● Special capacitor and inductor for audio purposes.
● 80 Hz crossover.
Remember, an audio crossover splits the incoming audio signal into separate bands that do not overlap at all and that, when added together, give the signal unchanged in both frequency and phase response.
