Automotive audio crossovers are a class of electronic filters designed for audio applications such as hi-fi. A commonly used dynamic speaker driver can cover the entire audio spectrum by itself.
The cross separates the audio signal into separate frequency bands that can be processed by individual speaker drivers optimized for those 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
The Kenwood KE-600 is one of the most advanced signal processors, a 6-way electronic crossover with built-in parametric equalizer and DC to DC power supply for high voltage output and low noise.
It features input selection, phase switching, variable level control and the following outputs: subwoofer, low pass, low cut, high cut and high pass. It is a great component for multi-amp installations and costs about $370.
feature
● DC-DC converter.
● High frequency output.
● Input selector.
● Different phase switches.
● Subwoofer output from 30Hz to 800Hz [low pass].
● 6-way multi-amp configuration.
● Variable level controls.
Kenwood KPX-F801 Crossover
The Kenwood KPX-F801 Crossover is a 3-way passive crossover network. It sells for about $75.
feature
● Protection circuit to prevent excessive tweeter input.
● Special capacitors and inductors for audio applications.
●Inverter switch for IF and tweeter.
Kenwood KPX-L101 Crossover
The Kenwood KPX-L101 Crossover is a low-pass passive crossover network. The current price is $50.
feature
● Special capacitors and inductors for audio applications.
● 80Hz frequency division.
Keep in mind that audio crossover divides the input audio signal into separate bands that do not overlap at all, and when added together, the signal remains constant in both frequency and phase response.
