What Is Midrange in Audio?

What Is Midrange in Audio

The midrange is probably the most essential part of the music. Why? Mids define the overall accuracy of a speaker. So in order to have things like clean highs or super low thunder bass, you need an excellent midrange that isn’t harsh, too forward, or undefined. 

What is the midrange responsible for?

The midrange is responsible for some of the most essential parts of the audio. They are responsible for producing midrange frequencies, which are considered the most important frequencies because they produce audible sounds such as musical instruments and the human voice. 

Having a good midrange means that everything can be balanced and delivered accurately. This is important because audio is layered in every instance, such as music, video, etc. Having a good midrange can balance all the sounds to provide a more clean audio experience.

Types of Midrange

There are three types of midrange. The low midrange covers 250 to 500 Hz. The midrange, which covers 500 Hz to 2 kHz. And lastly, the upper midrange covers 2 to 4 kHz. They all have their own specific duties to help produce quality sound.

Low Midrange = 250 to 500 Hz

The low midrange contains the low-order harmonics of most instruments. Therefore, it is generally viewed as the bass presence range. 

It boasts a signal of around 300 Hz and adds clarity to the bass, as well as the lower stringed instruments. However, anything higher than 500 Hz can cause the higher-frequency instruments to sound muffled. 

If a song sounds somewhat muddy, it is possible that an excess of energy is being produced in this region.

Midrange = 500 Hz to 2 kHz

This midrange is used to determine how prominent an instrument is in the mix. It boasts roughly 1000 Hz and can give instruments a horn-like quality. However, in the event of excess output at this range, the sound can come across as tinny and may even cause ear fatigue. 

If boosting in this area, be very cautious, especially in the case of vocals. This is because ears are particularly sensitive to how the human voice sounds, as well as its frequency coverage. 

Upper Midrange = 2 to 4 kHz

This is the range to which human hearing is most sensitive. These high midrange frequencies are capable, with a slight boost, of considerable changes in the sound timbre.

The high midrange is most responsible for the attack on percussive and rhythm instruments. When the upper midrange is boosted, it can add presence. On the other hand, too much boost, like that of the 3 kHz range, can cause listening fatigue. 

What to look for in midrange

A midrange should have a straight-flat frequency response. This helps it get that smooth sound. If the mids are exaggerated, the voices will overpower the rest of the sound ranges. On the other hand, if they are recessed, then the bass and the treble are left behind. This creates a hollow sound in the middle.

You want a midrange that gives you that smooth, flat, balanced sound that can match the highs and lows. It needs to produce the vocals perfectly while also balancing the instrumentation correctly. Audio is layered, so a midrange needs to be able to balance these layers and deliver the best sound possible.

How to get the most out of a midrange

Midrange speakers on their own don’t sound all that impressive. The human ear is sensitive to the midrange frequency. The driver can remain at lower power and still provide good sound in terms of volume and quality. But, because midrange speakers can’t produce extreme lows or high spectrum, they often sound dull.

In order to fully utilize an excellent midrange, it should be paired with a subwoofer, as well as a few tweeters. This will help to fill out the rest of the sound range. Another thing to consider is pairing midrange speakers with amplifiers and external crossover to direct the frequencies to correct places.

Subwoofer

A subwoofer is a speaker designed to reproduce low-pitched audio frequencies known as bass and sub-bass. The frequencies are lower than those which are produced by a woofer. 

Tweeter

A tweeter is a particular type of loudspeaker. Tweeters are usually dome, inverse dome, or horn-type in design. They are designed to produce high audio frequencies. 

Amplifier

Am amplifier is the device that turns the low voltage signals, from the source equipment, into a signal with enough gain to be used to power a pair of speakers. 

External Crossover

An external crossover divides an input signal into two or more outputs of different ranges of frequencies. It essentially acts as a manager, delegating tasks to the tweeters, speakers, subs, and more. As a result, each gets only the range of frequencies they were designed to play. 

Final thoughts 

The midrange is one of the most critical parts of the audio experience. It is something that most audiophiles take most seriously in their consideration of a speaker purchase or even the creation of a speaker. Having a thumping bass and other drivers like tweeters, subwoofers, and so on are all dependent on an excellent midrange. 

So when you are next shopping for a speaker, make sure to truly focus on the aspects of the speaker’s midrange. This will help you determine if a product is good enough to add to the additional drivers to produce a winning sound.
