The Top 8 Best 8 Inch Subwoofers of 2019

Overview

In this guide, we take a look at the best 8 inch subwoofers on offer.  We know - when you talk about subwoofers and their explosive bass-boosting powers, your first thoughts might wander towards subwoofers 12 inch or bigger.  But, you might be surprised that 8 inch subwoofers are actually a very popular choice among many people, and with good reason.

Why, you ask?

Well, there is no doubt about the fact a single 8 inch subwoofer will not transform your vehicle into a powerful bass box, especially if you’re comparing them with bigger, badder subwoofers. And that is clearly because larger subwoofers consists of more cone-area, which means they can generate a lot of air pressure – the outcome, a powerful, bass-boosted sound.

But, as we discuss below, 8 inch subwoofers definitely have their own advantages over their larger counterparts.

Here are some really important reasons why you should consider buying one of our choices for best 8 inch subwoofer for your car:

Musical Taste

This is more of a preference related benefit, for example, smaller subwoofers are really cool for genres such as metal, punk, techno and even classical and jazz music.

This is primarily due to the fact that these genres of music depend less on powerful, booming bass system, but rather a faster, crisper, more responsive level of bass, which is exactly what a smaller subwoofer offers.

Installation and Placement

There is no question about the fact that a small subwoofer can be conveniently installed and placed anywhere in the vehicle in comparison to their larger counterparts, which can only be placed inside the trunk, and may leave you minimal space in your trunk!  8 inch subwoofers can be placed in other parts of the car, without having to cut out large chunks of your dash etc.

Also worth noting, if an 8 inch subwoofer is adequately powered and is mounted in just the right position, the results can be significantly different.​

Flexibility

This is perhaps the best of all advantages because if you require additional bass, you can easily partner one 8 inch subwoofer with an additional 8 inch.  This is also a great way to increase the level of bass if you are finding one 8 inch is not enough for your personal taste.

Price

Finally, simply put - smaller also means a lot cheaper!

Ultimately, you may already be here for any of the above reasons, and dont need any further convincing.  

And so, here at CarAudioHQ.net , we have done all the grunt work for you.  Below are some of what we believe to be the best 8 inch subwoofers you can get your hands on:

Final Thoughts

Generally speaking, if you are into bass-heavy music and are looking to create a powerful sound system for your car - and you have the space available for installing a larger subwoofer, you may wish to go for a the large subwoofer solely because of increased sound it can generate.

However if you are looking for a bass solution that is affordable, or your musical taste favors a crisper, faster, more responsive bass sound - then you should definitely consider an 8 inch subwoofer.  And ultimately, the above is a fairly comprehensive list of some of the best 8 inch subwoofers that you can choose from.



Key Terminology

RMS

Audio companies generally advertise their products using terms like "MAX" or "Peak power".

Forget about all that. When we're discussing power, RMS is the only value that lets you make any sort of meaningful comparison between two products. Why is that?

Well, RMS stands for Root Mean Square. No math lessons here; this just means that RMS measures how much continuous power a component can handle safely.

Peak power is how high the system can go at maximum output, but it can't stay at that wattage for long without causing problems.

That's why devices that advertise "peak power" are being a little misleading. What's really important is sustained sonic output for an indefinite length of time.

RMS lets you quickly and easily compare power outputs between components.

This means a speaker with 200-watt MAX but only 60-watt RMS is less powerful than a speaker with 100-watt MAX and 80-watt RMS.

Range / Response

When we start talking about speaker range or frequency response, you might have a general idea of what we mean.

On the surface, it's pretty simple. Range is a measure of how much of the audible sound range the speakers can produce. It's measured in Hertz (Hz), with low numbers being long, deep tones (like the boom of a drum) and high numbers being shorter, sharp tones (like the singing of a bird).

Obviously, we're only concerned with the portion of the Soundwave we can hear. Human ears are capable of responding anywhere from 20Hz to 20,000Hz (or 20 kHz).

Range is a simple concept to understand, yet difficult to master. If you want to fully appreciate the implications of range and how it applies to audio equipment, you have to dive into some complex mathematics. That's beyond the scope of this article.

For now, just remember: Range is a useful way to measure how much of the audible spectrum a device can produce.

Please note - it doesn't tell you anything about the quality of that sound! Don't make a purchase based entirely on response.

Impedance

This fancy term just means how much AC resistance exists in the wiring of the speakers. Please note: Different frequencies can have different impedance values.

Generally, most loudspeakers will have resistance that ranges between 4- and 8-ohms. As long as your speakers have similar impedance to your amp, you'll be fine.

A higher impedance means that an amplifier will have to push more voltage to create the same sound quality. On the other hand, it also means a component can handle more juice without taking damage.

As long as you make sure these values are in alignment, you shouldn't worry too much about impedance.

Sensitivity

This isn't how fragile or delicate your speakers are; nor does it have anything to do feelings. This is a universal metric that simply tells you how much sound pressure (loudness) an audio device will create at a stated distance on a single watt.

What does this mean to you? The more sensitive your speakers are, the less power they require to produce the same amount of volume. Basically, it's translating more of that raw power into crisp audio goodness!

Depth

My first car was a 2005 Subaru WRX. I loved her, but she had very shallow door panels and it was a struggle to find speakers with a profile narrow enough to fit.

Depending on your ride, you'll have more or less room to work with as you build a stereo system. Make sure you don't make the mistake I did and assume depth is universal - you could save yourself some serious money and a lot of heartache. 

Work components around your car; don't work your car around components.

How much room will you need to mount the speaker in your vehicle? What's the difference between "top mount" depth and "bottom mount" depth?

Top-mount depth is how much room the top of the speaker needs from the point of installation. This is how far it 'juts' out into your car interior.

That means bottom-mount depth is how much room the bottom of your speakers need to clear the interior of your dash or panel.

For simplicity's sake, in our reviews we focus on the more commonly available measurement: top-mount depth.
