Car Subwoofer Crossover 80Hz or 120Hz

Audiophiles know the worth of having a good car audio system. And without a sub, it may seem colorless to listen to the music. A subwoofer can provide a powerful bass bump that enhances the overall listening experience, but you need to set the appropriate crossover frequency to ensure it’s working optimally.

There are two types of crossover frequencies that I suggest setting for your car subwoofer, which are 80 Hz and 120 Hz. Now you need clarification about which one to choose between car subwoofer crossover 80Hz or 120Hz. Read the article until the end to have a better idea of setting your crossover.

What’s a Crossover, and Why Is It Important?

Before diving into the depth, let’s know about the crossover settings. A crossover is an electronic circuit that splits up or filters a single input audio signal into multiple crossover frequency bands before sending it to the appropriate subs.

If you don’t use a suitable device (that has a crossover frequency knob), you will face muddy or distorted sound, as the amplifier will send too many high-frequencies to the car subwoofers.

As a result, this will cause damage to the speaker and overpower the subwoofer, resulting in a reduced overall sound quality.

So, setting the crossovers optimally is essential for enhancing the music quality by the car subwoofer to play the low-frequency bass clearly.

For example, tweeters are designed to reproduce high-frequency sounds, while midrange speakers are better suited for the middle range of crossover frequencies.

So, a balanced and natural sound is created across all car audio system components by directing corresponding frequency ranges through crossovers.

Furthermore, one significant benefit of using a crossover is power handling efficiency; effectively controlling what frequencies travel through each independent loudspeaker lets drivers send less power into them, thereby reducing distortion and extending their lifespan over time as critical components of your vehicle’s stereo system.

Note: In larger setups like home theaters with multiple surround sound channels or powered subwoofers, you may have more than one type of crossover that utilizes different networks like those commonly referred HP (high pass) and LP (low pass).

How Does the Crossover Frequency Affect the Performance of the Subwoofer in the Car Audio System?

As mentioned above, you must use optimal crossover settings to enjoy your car audio system. An optimal range will determine which frequencies to get through the subwoofer and when other speakers, like tweeters or mids, will take over.

For example, if you set the LPF too low (below 60Hz), you will get wasted energy since sound below such range is not audible to humans but the dogs. On the other hand, if set too high (above 120Hz), it may cause distortion and make some frequencies muddy-sounding.

For most car audio systems, I recommend having a crossover frequency somewhere between 80Hz and 120Hz. At such settings, you will get optimal efficiency since it ensures that small speakers, such as tweeters, handle the mid-range frequencies while the car subs reserve the low-end bass sounds.

Of course, various factors such as the size of the speaker and desired sound quality may warrant different crossover settings on a case-by-case basis – so experimentation is key here! Therefore, you need to set proper crossover frequency.

Car Subwoofer Crossover 80Hz or 120Hz

Let me give you a brief introduction before I differentiate the 80 Hz and 120 Hz for your car subwoofer. As mentioned above, the crossover frequency is when a subwoofer begins to produce the bass and then rolls off as other speakers (in the speaker system) take over.

he two most commonly used crossover frequencies for subwoofers in car audio are 80Hz and 120Hz; determining which one is better can depend on various factors, such as the size of the subwoofer, acoustics of the car, and personal preference.

1. Subwoofer Size:

Size is an essential factor that helps you choose the crossover frequency setting for your car audio system. Suppose you have a smaller subwoofer, such as an 8″ or 10″ woofer.

In that case, it may be better suited for an 80 Hz crossover point because these sizes are less capable than larger ones at reproducing lower frequencies without distortion or damage occurring.

By setting the crossover frequency at 80 Hz, you can ensure that your small speaker won’t try to reproduce sounds it can’t handle while still producing an excellent low-range frequency response in your speaker system overall. 

On the other hand, if you have a larger woofer, such as 12″ -15″, this size will typically be better suited for a higher crossover frequency, such as 120Hz.

This is because larger woofers are generally more capable of accurately reproducing lower frequencies. Thus, setting the crossover at 120 Hz can help achieve a more natural, balanced sound in your car audio system overall.

2. Car Acoustic:

The second factor that can affect the crossover settings is car acoustic. You may now think, how is it possible? Well! The acoustic environment of a car can impact both the quality and loudness of your sound system.

Car interiors are usually smaller than dedicated audio environments such as home theaters or studios and therefore require different approaches when setting up a speaker system.

Many people opt for higher crossover frequencies, such as 90Hz or 120Hz, to maximize volume output; however, this can lead to poor low-frequency response if specific acoustic properties in the cabin are not considered first.

Furthermore, you must also consider the vehicle size and sound-deadening materials used in the vehicle’s interior design. If you have a small car, you should use 80 Hz to achieve better bass response at lower volumes. However, if you have an SUV, you can take the Hz level up to 120 according to the subwoofer placement.

3. Other Car Speakers Capability:

Now let’s discuss the other speaker’s capability to bear the crossover settings. An 80Hz crossover frequency is typically considered more appropriate if your other speakers can handle mid-bass frequencies and high frequencies cleanly and accurately.

On the contrary, if your other speakers struggle with producing accurate sound at those frequencies, then 120Hz would be more suitable.

It’s a fundamental reason because the crossover settings affect how well each speaker reproduces the sound (rather than the subwoofer) in its designated bandwidths: lows for the subwoofer, mids for midrange drivers, and highs for tweeters.

When you set an 80 Hz crossover frequency on the head unit or aftermarket amp in a car sound system, any crossover frequency below 80hz gets sent to only the dedicated low-frequency driver—the subwoofer—while all frequencies above 80hz get split between both subs, and either midrange drivers or tweeters (depending on what kind of setup you have installed).

Conversely, when selecting 120hz as a crossover point with this type of separate setup (an external amp/processor driving two-way passive components), any signal below 120Hz gets sent exclusively to just one dedicated subwoofer.

In contrast, the frequencies above 120Hz get divided between both subs and midrange speakers/tweeters.

About 80Hz Crossover Setting for Car Sub:

If you want to get the most out of your car audio system, setting up an 80Hz crossover is a great place to start. This setting helps to separate the lower frequencies from higher frequencies, allowing each part of your sound system to perform at its best.

With this setup, you can ensure that your subwoofers can deliver powerful bass tones without overpowering the other speakers in your vehicle.

In addition, it will help keep distortion levels low and improve overall audio quality. Let’s have a look at some of its benefits:

1. Better Sound Quality:

I prefer 80Hz more than 120Hz because it allows you to separate low-frequency sounds from higher-frequency sounds (trebles), ultimately creating a more balanced mix that you can enjoy without distortion or muddying up other instruments in the combination.

Better separation between crossover frequency ranges also helps create an immersive listening experience. Every instrument and vocal track will have its own space within the mix rather than competing for sound dominance.

With a correctly set crossover, bass sounds will remain punchy while allowing mid-range and treble notes to stay clear even when played at high volumes.

It also reduces strain on all components since they’re only being asked to perform within their capabilities rather than pushing too hard or too little output from them.

2. Improved Bass Response:

Bass! That’s all that we, audiophiles, crave for. When I talk about the bass tones, I’ll also suggest you set the crossover frequency at 80Hz to get the most out of your car subwoofer.

As mentioned above, audiophiles use crossover frequencies to divide an audio signal into two separate bands: low-frequency sounds (the bass) and high-frequency sounds (the treble).

Setting the crossover at 80Hz allows the subwoofer to handle the lower frequencies more effectively, resulting in an improved bass performance with greater power and impact.

This feature is handy if you fan genres like hip-hop or electronic dance music that rely heavily on solid beats and bass lines.

Properly configured low-end frequencies help bring out all of these musical elements, adding an extra level of immersion when enjoying these genres of music.

3. Reduced Strain on Other Speakers:

By setting the low-pass filter at 80Hz, you can prevent lower frequencies from traveling through other speakers in the system, reducing strain on those speakers, preserving their life, and improving overall audio quality.

Using an 80Hz crossover frequency for your subwoofer specifically would prevent any “distortion bleed” caused by high levels of bass traveling down into other components like amplifiers or midranges/tweeters to keep all parts running uniformly throughout playback cycles.

This reduces strain on different speakers and prevents damage that could be caused by excessive bass coming through them due to the crossover filtering it out.

About 120Hz Crossover Setting for Car Sub:

Now let’s talk about the 120Hz! One popular choice among car stereo enthusiasts is the 120Hz crossover setting, designed to separate midrange frequencies from higher frequencies to create a more balanced sound experience.

This setting works by sending signals up to 120 Hz through your subwoofer and allowing other speakers in the system to access all frequencies above that level.

As a result, this ensures that any bass notes will be heard loud and clear while mids and highs remain at their optimum level without distortion or interference.

Let’s have a look at some of the benefits of setting 120Hz on a car subwoofer:

1. More Natural Sound:

Actually, 120Hz will provide you with a more natural sound than if you set 80Hz. This is ideal for those people who want to enjoy the music every bit.

The reason for this is that the human ear perceives sound differently at different frequencies, and by delivering the midrange frequencies to the subwoofer, you are allowing it to blend these mids with the bass frequencies more effectively.

As a result, you will get a much smoother transition between crossover frequency ranges instead of hearing distinct “cuts” when one crossover frequency range transitions into another.

For example, when using a 120Hz subwoofer setup in your car stereo system, you can detect the nuances of instruments like violins and guitars that play notes within this range. It helps bring life and clarity to any music track played through your speakers.

2. Better Voice Clarity:

Another benefit is that you can hear improved vocal clarity when listening to genres that include vocals or other types of speech.

That’s because the subwoofer can handle the midrange frequencies more effectively, resulting in more precise and intelligible sounds.

Having a 120Hz rating also helps you get better sound quality when listening to music with many basses since it allows the woofer to produce deeper sounds.

Frankly speaking, if your system has speakers with higher sensitivity ratings (generally 90dB or higher), then using a 120Hz crossover point would be ideal.

Setting a high enough cutoff frequency is crucial because it will ensure that low frequencies are passed through efficiently without affecting audio quality from mid and high-range frequencies; this makes dialogue much easier to understand than at lower speeds like 80Hz and below.

Which Should You Use Between 80Hz and 120Hz for Car Subwoofer?

Whether to go with 80Hz or 120Hz should be based on the music you typically listen to and the type of bass sound you prefer. Generally speaking, a higher crossover frequency setting gives you more detail in sound reproduction at mid-range frequencies.

In contrast, a lower setting will emphasize low-frequency sounds like those found in hip-hop and electronic dance music.

I suggest a lower setting, such as 80Hz, if you want a “boomy” sound that emphasizes low notes, while higher settings give off more clarity and detail when listening to rock or jazz music.

Keeping this in mind, an 80HZ can provide ample power for any genre and is often preferred by many audiophiles who desire loudness without compromising control over their bass response.

At 120Hz, however, your subwoofer will have less range but put out more power thanks to the higher frequency. This can be advantageous if you’re looking for a more intense bass experience, but it may also lead to a muddier sound if your music contains too many low-frequency notes. So, always choose the best crossover frequency to enjoy the music.

Is 120Hz Crossover Too High?

In general, a 120Hz crossover setting is considered suitable for most car subwoofers since it falls within their range of midrange frequencies that they can effectively handle.

This type of configuration typically results in a more natural and balanced sound quality that blends bass frequencies with midrange frequencies seamlessly.

However, other speakers may not be able to handle higher frequencies as well as these lower ones, leading to an uneven sound quality where specific crossover frequency ranges are overemphasized or underrepresented.
