Subwoofer Equalizer Setting: Get the Deep Bass

Although most sound systems have built-in techniques to control and mix the frequencies with sound levels in today’s modern era.

More passionate music lovers have their own way of matching different tones in some or the other way.

This is when an equalizer comes into the picture.

Additionally, if the setting on the equalizer is not set right, then the fun and satisfaction of listening to the music will remain intact.

This is especially true for people who love to mix bass at different sound levels for a specific musical genre.

Let us understand what an Equalizer is and a few settings that add bass at different sound levels according to the type of music or genre.

What is an Equalizer in sound systems?

An Equalizer is an electronic device used to adjust the volume of different frequency bands within an audio signal.

In the world of music, it is also referred to as ‘EQ’ and is also available digitally.

These Equalizers typically isolate a certain range of frequencies and allow output on set sound levels.

Built-in subwoofers, speakers, and similar sound systems have a built-in Equalizer in the form of a circuit.

In most cases, especially the music systems that are designed for concerts, cinema halls, pubs, DJs, other public events, etc., require an additional Equalizer unit.

Equalizers are also used in sound recordings and reproduction by many professionals and artists.

Where are Equalizers used?

Equalizers are typically used in many sound systems such as Home stereos, Car stereos, studio recording and/or mixing boards, Guitar pedals, rack effects, and other large sound systems, etc,.

Additionally, Equalizers are quite popular in instrumental amplifiers such as Bass, Guitar, Keyboard, etc.

Most sound systems have a built-in Equalizer circuit with standard settings and some need an external unit.

The advancement in technologies has made them available in the form of digital software that can be installed on computers, smartphones, and tablets.

Are Equalizers necessary for subwoofers?

Equalizers play an important role when it comes to fine-tuning different types of audio notes. It acts like an audio filter in boosting, lowering, or leaving certain frequencies unchanged.

Different musical notes correspond with different frequencies (Hz). If you have music systems with different sets of speakers and subwoofers and prefer to boost the bass effect in your favorite music, you can adjust the sound levels of the lower frequencies to add more boost with the help of an Equalizer.

You can also reduce the sound levels of certain frequencies as per your preference.

What is the bass range setting in Equalizers?

The frequency range for the boom-bass effect always lies at the lowest points which typically ranges between 20Hz to 200Hz.

If you refer to the image below it is an infographic example of an Equalizer used in different sound systems.

The image shows the sound level (dB or Decibels) ranging from 10 to -10 as an example.

Also, the frequency levels are split into different ranges vertically.

The frequencies that help to boost bass are highlighted in the below image and can be adjusted to customize your musical note.

This means you will need to adjust the decibels in the range of 20Hz to 200Hz to maximize your bass-heavy boost.

It is not always necessary to adjust the entire range in that category and you can experiment with the set to reach the bass boost level of your choice.

What is the best bassline setting for hip-hop on Equalizers?

To get the best bassline settings for hip-hop you can adjust or increase dB around 60Hz frequency on the Equalizer.

It is a preferred range for most system types because bass-heavy synth pads typically sit around that range.

You can refer to the image below that demonstrates the increase in the frequency range of around 60Hz to set the best basslines for hip-hop on an Equalizer.

In some cases, you will need to cut off or reduce the frequencies below 50Hz and it may be applicable for low-end subwoofers.

This is not always required, however, if the output of the sound distorts or seems muddy then you can try by applying the above setting.

How do you set bass for rock music on Equalizers?

Rock music is sometimes difficult to adjust on Equalizers and requires special settings. It is because you will need to mix the sound levels of mid-low frequencies for bass with the mid-highs properly.

The professionals use the term ‘Rock-Curve’ which is typically referred to due to the curve formed on the Equalizer after applying the settings.

You can refer to the image below of an Equalizer setting that forms a curve after the best settings are applied for rock music.

The low and mid-low frequencies on the left are the ones that control the bass level and increasing them will output louder bass.

Similarly, the other side controls the sound levels of higher frequencies.

The lowest frequencies are set from louder to falling down towards the midrange being the quietest.

Likewise, the higher frequencies are set from louder to falling down towards the midrange being the quietest.

Note – The settings explained above may slightly vary depending on your sound system type, size, specifications, controls, etc,.

Final Thoughts 

Equalizers can be great at boosting the sound levels of low frequencies to output louder bass.

Although, you can gain that extra punch to the bass, unfortunately, it may not work out with every genre.

Most sound systems have built-in Equalizers in the form of a circuit. It adjusts the sound levels of different frequencies automatically according to the musical notes.

Equalizers as an outward or external unit are popularly used in many sound applications to customize sound.
