Advantages of using Variable low pass Crossover

Variable low pass Crossover will give you the ability to vary the filter bandwidth and the filter type. This means that you can change the filter frequency from 20hz to 500hz. This means that the low pass crossover will give you a more “open” sound. The open sound is where the low frequencies of the audio are heard, and the high frequencies are heard as if they were out of the speakers.

I have written this article for the purpose of discussing the Advantages of using Variable low pass Crossover. This will help you to decide whether to use a Fixed or Variable low pass Crossover.

In this article, I will be writing about the Advantages of using Variable low pass Crossover.

What is variable low pass crossover? (Definition)

Answer: Variable low pass crossover filters the frequencies below a set point.
In this way, you can adjust your car stereo input signal so it can be played on a home speaker system without distorting the output. Additionally, a variable low pass filter provides better sound quality for music because it widens the frequency response curve.

So while I can’t say for sure how any amplifier will benefit you, I can tell you what a Variable Low Pass Crossover does and why it is important – so hopefully that gives you some insight into whether or not it would help your situation. 🙂

Advantages of using Variable low pass Crossover

A Variable Low Pass Crossover allows you to adjust (or vary) how low or high your speaker’s frequency will go before they are cut off by the amplifier.

This way, you can ensure that your speakers are getting the frequencies they need without being overpowered by other sounds that they shouldn’t be receiving.

For example, if you have a subwoofer – you probably don’t want it trying to play high-pitched songs where only the vocals and instruments come through. By setting your low pass crossover at a lower frequency, you can ensure that the bass is not overpowered by these higher frequencies.

What are the Potential Advantages of using Variable low pass Crossover?

The potential benefit of the variable low pass crossover is that you can get more out of your speaker system. You can set the bass below 80Hz so it doesn’t interfere with the higher frequencies and vocals on rock songs, while still getting some thump for dance music.

This is where high-level inputs come in – these allow you to connect your RCA cables to a factory system without any special adapters or whatnot. This way, you can keep your factory head unit and amplify the speakers directly from the RCA output.

-Variable low pass crossover allows you to adjust how low or high your speakers will go before they are cut off by the amplifier.

-It has one set of RCA inputs and one set of speaker level inputs to connect it to your vehicle’s factory radio system.

-2000 watts max output can handle up to 4 Ohm speakers.


1. What is the best crossover frequency for a car subwoofer?

Answer: Subwoofer crossover frequency is a set point that the signal sent to the subwoofer has to cross. The most popular frequency range for a subwoofer is anywhere from 50-150Hz, but it’s really up to your personal preference and what you want from your car audio system!

2. Does a crossover improve sound quality?

Answer: A crossover is a filter on an audio speaker system that directs specific parts of the frequency spectrum to each individual speaker and helps to correct impedance mismatches and acoustic phase errors. This results in sonic improvements such as tightening up the bass, lowering distortion levels, increasing sound pressure levels due to reduced driver coil losses, and reducing coloration from lossy signals such as mp3s or streaming videos.
