Benefits Of Using Capacitor For Midrange

Before we talk about the benefits of using a capacitor in your speaker, you need to understand how a capacitor works. We’ll explain it as simply as we can.

You see the audio frequency range that speakers cover is traditionally in between 40 Hz and 20 kHz. This is a huge range and your speaker drivers can only cover so much of it.

A capacitor forms part of a system called the speaker crossover. The capacitor along with resistors and inductors in your speaker setup makes sure that your speaker doesn’t get overloaded with audio signals of varying frequencies.

The capacitor stores the electrical energy from the lowest and highest frequencies to make sure that your speaker isn’t bombarded with extreme values.

So how does this help your speaker? First, it protects the speaker from constantly having to process these signals. This prevents a lot of potential damage.

On top of that, the quality of your audio is going to be much better. First off, you won’t hear those extreme frequencies which gives a much more consistent feel. Secondly, there is going to be a considerable decrease in the amount of distortion. This is a big win in our books.

So now that you know what a capacitor does and how it makes your audio output better, let’s find the best capacitor for midrange speakers to become a part of your personal audio system.

Our Top 5 Capacitors For Midrange Audio in 2022

1. Genteq c3455r speaker capacitor

Genteq c3455r capacitor

Genteq is quite a reputable brand when it comes to non-polar electrolytic capacitors. In fact, we kick the list off with an excellent product from them. This is a solid capacitor for midrange speakers that should provide a significant boost to your audio performance.

With a capacitance of 45/5uF over a 370V output, the capacitor has more than enough storage to get the job done. As a matter of fact, you don’t need more than 4.5uF for the midrange.

The round shape is great as it allows you to connect to a large variety of systems without much hassle. Installation is not going to be too much of a headache as you won’t be faced with any compatibility challenges.

The durability is good too. The polypropylene body can handle a bit of damage but we heavily recommend keeping it safe from any external factors.

As for aesthetics, this looks pretty standard. We like the silver color and the blue label. Also, it is a tad bit slimmer than other round capacitors, so that wins points as well.

All in all, this is a very well-rounded capacitor and as such is a very strong contender for best capacitor for midrange. The only complaint we have is the capacitance may be a little overkill.

Highlighted Features:

  • Great Allrounder
  • The round shape is universally accepted
  • Durable polypropylene body
  • Nice silver aesthetic
  • The capacitance of 45/5uF over a 370V output may be a little too much

2. Power Well 45+5 MFD Round Capacitor

Power Well 45+5 MFD

Powerwell is another brand name that towers above others when it comes to the audio capacitor industry. This product is a testament to why this brand has earned its good reputation.

We should start by talking about its durability. This capacitor is built like a tank. Not only will it last for a very long time but it can also survive a tumble or two. Again, we would like to remind you that just because it is sturdy, doesn’t mean you act callously in its protection. An audio capacitor is never meant to undergo any physical damage of any sort.

But on that note, we would like to add that if you take adequate care of this component, you will not have to worry about wear and tear for a long time due to the excellent dual-run setup.

The shape is round for this product as well and as we mentioned before, this is a readily available shape that will be compatible with most speaker setups.

The capacitance is the same as the last product, 45/5uF over a 370V output. The only added benefit is that it can operate on the same level at 440V output as well. As we said, this capacitance might be a bit more than you need in a home stereo system.

The appearance takes a massive hit to facilitate the increased durability in our opinion. It is a lot thicker which looks less flattering.

Highlighted Features:

  • Most durable product on this list
  • The round shape is easy to work with
  • 45/5uF over a 370V or440V output is a bit excessive
  • Appearance is somewhat cumbersome

3. Planet Audio PCBLK2.0 Car Capacitor

Planet Audio PCBLK2.0

Remember how we said that 45/5uF is a lot more than you could possibly need for a traditional home audio system to boost the midrange performance. Well, this stereo capacitor can store 2 whole farads. To put that into perspective, that is 2,000,000uF.

This must be a massive downside, right? Well, no. That is because this capacitor is specifically built for car amplifiers. Car audio systems are set up in a very unstable environment and such the range varies greatly, this means you need a capacitor that can store a lot of energy.

Cue Planet Audio PCBLK2.0. This is the perfect capacitor for this job. Along with the huge capacitance which is sure to pump up the bass of any music you listen to in the car, it is also quite durable.

The materials used seem to be high-quality and the bright led display and audio cues keep you notified on reverse polarity, voltage overload, low battery voltage, and other voltage-related issues.

It looks pretty cool too. The blue and black design coupled with the led display makes it look like futurist tech.

The issue with this product is pretty apparent. You cannot use this in a home audio system. This is going to make your midrange audio sound muted and the clarity will be poor.

Highlighted features:

  • Perfect stereo capacitor for a car
  • Great durability with multiple warning features
  • Cool aesthetic
  • 2 F is far too much for a home audio system

4. PowerWell 40 + 5 MFD Dual Run Capacitor

PowerWell 40 + 5 MFD

This can be considered the little brother of the previous entry from Power well as the two products are pretty similar. We say this because it is a little less durable. The only other discernable difference is the capacitance but more on that later.

Let’s start with an interesting feature we merely glossed over when discussing the 45/5uF unit. The dual run system is a method that makes this one of the sturdiest Capacitors for Crossover Audio Circuits. How so?

The dual run system supports two motors instead of one, and as such, it is built to sustain a lot more energy input than traditional capacitors. Top this with the excellent quality control done by Powerwell, you have yourself a very long-lasting product.

Like all of the other home audio system capacitors so far, this is a round capacitor. Again, this is super convenient as these capacitors fit into most speaker setups.

Now, let’s finally get down to what makes this product different. The capacitance of this product is nominally lower at 40/5uF over a 370V or 440V output. While this may not seem like a massive difference, it might impact the quality of your audio quite a bit.

Remember we are dealing with very fine margins as is, the minimum capacitance you need is 4.7uF. So, this puts the 5uF difference in a new light. This slightly lower capacitance may boost your audio output significantly.

Highlighted Features:

  • Sturdy and reliable capacitor
  • Dual-run system and quality control makes it long-lasting
  • The round shape is easy to install
  • 40/5uF over a 370V or440V output is better suited for a home audio system.

5. Genteq GENTEQ – C307L GE Capacitor

Genteq GENTEQ - C307L

Last but not the least, we have a product that is essentially tailor-made to be a capacitor for midrange speakers. Genteq’s second product stands out quite a bit in a lot of ways.

Firstly, it has a much lower capacitance than other products. We’ve been talking about how the capacitance has been overkill for a while now. This carries 7.5uF at 370 Volts. This is ideal for your home audio system.

Secondly, this is an oval capacitor. While this may be seen as a downside as round capacitors fit in more easily into most systems, if you have a system that is compatible with an oval system, this is your most efficient option.

The durability is also pretty decent. It doesn’t stand out but you have nothing to worry about, it’s not a flimsy product by any means.

The only downside for this product is the appearance. The charm in the aesthetic of the Genteq c3455r is lost in this considerably chunkier unit. This is unfortunate as this is all that limits it from being the perfect pick.

Highlighted Features:

  • Specialized oval capacitor for midrange speakers
  • 7.5uF at 370 Volts is perfect for midrange audio
  • Decent durability
  • Chunky appearance

Things To Consider Before Buying Capacitor For Midrange Speaker

Now that you’ve found the most useful capacitors for crossover audio circuits, you have to pick one that is perfect for you. To do that, you need a comprehensive buying guide, and here is one to help you differentiate between these quality products.

Type of Capacitor

This is not a major concern. Generally speaking, non-polar electrolytic capacitors are perfect for home audio systems. It is cheap and efficient for this function. As such, it makes no sense to go for a fast and expensive component like a solen capacitor.

What Is The Capacitance Of Your Capacitor?

Capacitance should be one of the deciding factors when purchasing a capacitor if it wasn’t obvious enough from the name. This depends mainly on the speaker in question. For example, a home audio system would only require 4.7uF. In sharp contrast, a car amplifier would need a lot more capacitance.

What Shape Is It?

The shape also depends on the speaker itself. Most speakers work comfortably with a round capacitor but there are a few capacitors that need oval-shaped ones. See what your setup needs before making a purchase.

How Durable Is It?

Again, this is very important. It’s not like this is going to be under fire. We repeat you need to keep it away from any potential damage such as water, blunt force, or fire. But those with good materials and circuits should last for a very long time.


This is the least of your worries but still, it might also be a deciding factor. You won’t be seeing this component often but if it is just for your peace of mind, a good design can go a long way.
