Pros And Cons Of Variable Bass Boost

Tired of feeling like your bass is washed out even when the song calls for it? Well, there’s an easy solution. Just turn on that boost button and give yourself some extra low end. But this works with every artist or genre. 

What about those genres where subwoofers are key? In today’s article, we will discuss how variable bass boost works so you can decide if using one might be right for you, too, in-car audio systems.

Pros of variable bass boost

The best reason to use a variable bass boost is the amount of low-end you can get from your system. If there’s not enough bass in a song or genre for your car audio system, turn on the boost and enjoy. It evens out the difference between songs and makes them sound better no matter what type of music you listen to. Artists like Taylor Swift usually do not have much bass, but sometimes unique beats will benefit from this feature.

With the Variable Bass Boost, you can dial in precisely what low-end type is desired. For example, this might be a hurdle if a car’s speakers lack depth and total frequency response. To reproduce optimal sound quality for modern music tracks requiring bass bumps or thumps. In factory systems It may take some finessing with EQ settings on your dashboard, but when all else fails, we’ve got ya covered. Just turn up 60Hz at times where smooth jazz sounds excellent through its entirety.

It is straightforward to use a Variable Bass Boost. Simply push a button-up for more bass, which will automatically adjust your EQ settings. Some may want more power and depth at times- while others can go without it altogether. This allows you to change things up when desired.

Variable bass boost just sounds better than most factory systems with any type of song or genre due to its ability to compensate acoustically for such variations in sound quality. Not just the low-end level provided by factory systems lacking newer technology.

This is fantastic if you enjoy all different types of music genres and need a system capable of adapting itself on demand. So you never have to be bored or disappointed again during car audio listening experiences.

Cons of variable bass boost

Sometimes, it’s hard to find that “sweet spot” with the Variable Bass Boost. If the bass is turned up too high, it can overpower the mids and highs in a song and make it sound muddy. This is usually not a problem with genres such as classical or rock, where there is already more emphasis on the lower frequencies.

In some cases, you may not need the Variable Bass Boost at all. Factory systems that come in most cars these days have variable bass boost built-in, so you don’t have to stress about finding an aftermarket product to install.

If your car doesn’t come standard with a sound system, variable bass boost can be a great additional feature to have. In this case, though, some people would argue that it’s better just to upgrade your stock system instead of applying a band aid type fix like adding Variable Bass Boost.

When the low frequencies are increased over time, you’ll begin to lose clarity. Some factory systems, on the other hand, may not be affected at all by this feature. If you want to upgrade your factory receiver and don’t have a subwoofer, make sure it has one. Variable bass boost is only beneficial on systems that lack low-end bass and can assist compensate for speakers that do not produce adequate sound quality. When listening to music with complicated instrumentation or voices.

It can be very complicated to find the perfect adjustment for any equalization (EQ) settings when using variable bass boost. If you adjust one side up or down, you will need to do the same with the other unless you want different frequency ranges to sound imbalanced.

Variable bass boost can’t make up for ALL frequencies in songs and genres out there– only those within the bass range (60Hz). This could affect things like vocals or instrumentals during certain music tracks, making them hard to hear or understand.


At last, it is up to the person listening to decide if using a variable bass boost is suitable for them and their car audio system. Of course, there are pros and cons to this type of product, but it can be a great addition to any car stereo if used correctly. With the wide variety of music available today, it’s nice to have a device that can make all of it sound good- even if you don’t think the system itself is up to par.

Variable Bass Boost seems more useful on factory stereos but works excellent with aftermarket setups. A Variable Bass Boost will help you get more out of your car audio, no matter what kind of sounds you are into or whether professionals installed your system at an auto shop or yourself. But, of course, it just might take some trial and error to find the perfect bass level for each different song.

What are the types of Variable bass boost?

There are two types of Variable Bass Boosts: mechanical and electronic. Mechanical devices use levers on the actual speaker’s frame to vary bass, while electronic types do not affect the speaker but boost the bass signal of your music.

What are adjustable subsonic frequencies?

Some devices also come with adjustable subsonic frequencies, which allow you to cut very low frequencies below 20Hz without affecting your speakers or subwoofers. This is good for car audio systems that cannot produce such low frequencies (the usual lowest notes made by car speakers are around 40Hz).

Variable Bass Boosts also help compensate for subsonic content in songs that may be boosting certain parts of their track for artistic purposes. Still, not all types of music or soundtracks have this type of content, so they can benefit from using a Subsonic Filter.


Frequently Asked Questions – FAQ's

A. Speakers and subwoofers should generally be able to take a bass boost. The only potential for damage is when the SPL is exceptionally high. Boosting the bass at loud volumes has the potential to cause harm. Boosting the bass shouldn’t create any problems if the book is moderate.


A. The degree to which the bass boost is used will vary, with some people preferring more of a thumping effect and others preferring a punchier sound. The majority of the time, though, this control is left in its original setting. This is because most bass boosts have some sort of low-pass crossover adjustment that adjusts how much high-end gets cut off when the subwoofer is playing at maximum volume. This can be useful if you’re trying to compensate for a tremendous amount of treble in your system or simply want to add more impact to your music. 

However, while it may improve performance in certain situations (such as when watching movies), using too much bass boost can introduce distortion at higher volumes, resulting in reduced power output and increased distortion over time.

A. If you want to use the bass boost, listen to a 40Hz test tone as you’ll be able to see how much growth you can give before distortion reaches 1%THD. You may also place your hands on your ears and press them tightly together while listening for the highest clean volume of the HU.


A. The best bass for most subwoofers has a frequency range of 20-120 Hz. The lower the Hz, the more bass you can acquire. The best subwoofers available have a Hz range of 20-80. If you aim to get the best out of your subwoofer, make sure it has a fixed Hz range (20-120).
