How Subwoofers Work

You already know that the job of a subwoofer is to enhance bass audio, but how exactly does it accomplish this? A subwoofer operates with the help of a large woofer - the part of a speaker that handles low frequencies - and a built-in amplifier. These two parts work together to create a signal that is lower in frequency than can be handled by standard speakers.

Modern-day subwoofers typically feature a powered system, rather than a passive one. This means that they use their own power supply instead of needing an additional power source. In order to function properly, a subwoofer must be connected to an audio receiver or preamp. Then, low-frequency signals are sent from the receiver to the sub, and the sub amplifies the signal into audible noise.


Types of 8-inch Subwoofer Speakers

  • Component/Standard Subwoofer
    A standard subwoofer, also called a component sub, comes with no enclosure and no amplifier. This is basically just the speaker with nothing else included. An additional amplifier and subwoofer box are needed for a component subwoofer to operate correctly. This is the ideal type of subwoofer if you’re hoping to personalize your audio system.
  • Powered
    A powered sub is the best choice if you're looking for a simple system that saves on space. This type of subwoofer is an all-in-one system that is small in size, but mighty in sound. The main perk of choosing a powered subwoofer is the easy installation, perfect for improving car audio.
  • Enclosed/Bass Tube
    An enclosed subwoofer is enclosed within a protective case. This type of subwoofer has been pre-mounted into a boxed enclosure for optimal protection and enhanced sound quality. Many people assume that an enclosed sub will create muffled noise, but this is not the case. In fact, enclosed systems create a more precise, accurate sound.
  • Vehicle-Specific/Amplified Bass
    A vehicle-specific sub can be either powered or unpowered. This piece of audio equipment was designed to fit flawlessly within the interior of a car. Many are even made to match the car’s interior color. If you’re looking for powerful bass in your car or SUV, invest in a vehicle-specific sub.

Benefits of Small Subwoofer Speakers

All speakers come with something called a woofer, which is the component responsible for handling low-frequency sound. Unfortunately, the small woofers within many speaker systems aren’t ideal for handling bass. The main benefit of investing in a small subwoofer speaker is that it is specifically designed to produce high-quality deep bass. You never have to worry about choppy, unpleasant bass again.

So why a small subwoofer speaker? Small subwoofers are the ideal choice because they are highly portable, lightweight, and easy to handle. Subwoofers that measure only 8 inches in diameter can be used in nearly any space. In addition to the fantastic space-saving abilities, here are a few more benefits of small subwoofer speakers:

  • They help to improve both low and high frequencies
  • They create a smoother all-around sound
  • New subwoofers feature easy installation

Choosing a High-Quality 8-inch Subwoofers

Power Output & Handling/Volume/Sound Quality

Power should be a top consideration when selecting an 8-inch subwoofer. More power means a louder boom, and a louder boom means a more enjoyable listening experience. Measuring the power of a subwoofer is done with two sets of numbers: peak power and root mean square (RMS) power.

RMS should be considered before peak power since it has to do with how well the subwoofer continuously handles power. Generally speaking, greater power is always better. In addition to power, look into things like maximum volume and overall sound quality. Sound quality is affected by many factors, so be sure to read plenty of 8-inch subwoofer reviews to get a better idea of how a subwoofer sounds.

Frequency Response/ Range

Frequency response is a measurement of how well a subwoofer can handle low frequencies. Since 8-inch subwoofers are smaller in size than large subwoofer models, the range of frequency handling might not be as broad. The typical frequency range of a subwoofer for the home or car is between 20 and 200 Hertz. To put things into perspective, professional subwoofers used for concert venue audio typically operate below 100 Hz.

Impedance

Impedance has to do with how well a subwoofer can handle power and its electrical current flow. It is measured in ohms. MTX Audio says this about impedance

“A higher impedance load will result in less amplifier output for that impedance, for example an amplifier will output more power at 2 ohms than at 4 ohms.  Amps can generally be safely wired at 4 or 2 ohms and some even at 1 ohm depending on their design.”

Sensitivity

Sensitivity and power output go hand in hand. A subwoofer with a high sensitivity rating is more sensitive to power, which means that it needs less power to produce high-quality sound. The higher the sensitivity, the better the sound, and the less power required. The best 8-inch subwoofers feature a high sensitivity rating, typically above 84 decibels. 92db is even better, so consider yourself lucky if you find a sub with this rating of sensitivity.

Placement

Where do you plan on using your 8-inch subwoofer? At home? In the Car? Not only where do you plan on using it, but also how. Is this for jamming out to classic rock tunes while using your in-home rowing machine, or is smooth jazz more your style? Considering the subwoofer placement and how you plan on using it is a must.

Voice Coils

There are two common voice coil options for subwoofers: single and dual. A sub’s voice coil system has to do with how the audio component is wired. The more popular choice is the dual voice coil subwoofer since this offers more flexibility in terms of wiring. Instead of only having one option for wiring the system, a dual voice coil has two separate connection paths.

Wired or Wireless

The main difference between wired and wireless subwoofers is that one is easier to install than the other. Obviously, wireless subs feature a more straightforward installation process than audio equipment containing wires. However, some subwoofer users feel that wireless subs are less reliable than wired ones. If you're not comfortable with a wireless connection, go for the traditional wired subwoofer.

Cone Size/Material & Subwoofer Dimensions

The cone of a subwoofer is the mechanism that is ultimately responsible for producing low bass. It does this by moving back and forth, and it is the only moving mechanism of a subwoofer. This is the main reason that choosing a durable cone is a must.

For the ultimate compact durability, look for materials like polypropylene, Kevlar, carbon fiber, and aluminum. Not only should it be durable but also compact. This is a given for subwoofers that span only 8 inches. Small size is especially important if you plan on using this subwoofer to enhance the audio of your vehicle.

Extra Features

If you plan on using your subwoofer for long periods, consider additional features like a motor cooling mechanism. This specific feature will keep the subwoofer from overheating during long listening sessions. Another cool feature is automatic on/off capabilities; as soon as the sub detects an audio signal, it turns on and starts playing music. Some subwoofers even come with remote control operation.

Enclosure Type

Unless you invest in a component subwoofer, your new sub is likely to be enclosed in one way or another. The enclosure type just refers to the kind of box that the subwoofer is contained within. Enclosure plays a role in many things, including noise quality - like whether the bass is “tight” and accurate.

There are two main types of enclosures for subwoofers: sealed and ported. Sealed enclosures are common because they create natural-sounding bass that is not prone to excessive spikes and dips. This is the ultimate choice for avid music lovers, particularly fans of classical and jazz music. The only drawback is that sealed enclosures require more power to compensate for the air pressure contained within the sealed box.

Ported subwoofers come with vents along the length of the enclosure box. These vents allow airflow that essentially creates a more powerful low bass sound. If deep bass is what you're after, a ported enclosure is the better option. The downside of a ported subwoofer type is that installation is trickier, plus they tend to be larger and take up more space.

Durability/Warranty

A durable subwoofer is likely to come with a manufacturer’s warranty. Most subwoofer warranties only last for a year or two, mainly because subwoofers are not expected to last forever. Do your research on company warranty policies, as well as the ease of making a warranty claim if subwoofer operation goes south.

JL Audio specializes in all-in-one subwoofer audio systems for vehicles. The company's CP108LG-W3v3 model can be used in either the home or car, and it is our top of the range model for a few reasons. The first reason is that this features an enclosed slot-ported system, so you won’t have to purchase a separate enclosure piece before installation. The sub itself is just 8 inches in diameter, but the entire unit is a bit larger, measuring 5.125" D x 18.500" W x 11.125" H. 

Another loved feature of the JL sub is the high-performance music output. Typically only much larger subwoofers are capable of producing the powerful bass that comes from this model.  The precise tuning of its 8W3v3 driver is to thank for this. Many JL Audio users are surprised - and pleased - by the powerful noise that comes from this small audio device.

Because of the thin yet durable wall material used for the enclosure, the internal volume of the subwoofer is about the same as the external volume. To create the necessary low-tuning frequency, JL Audio has made sure that the design is optimal for excellent extension and response smoothness. CP108LG-W3v3 technology utilizes a cabinet-building technique that makes the enclosure assembly more efficient and exact.

 The only downside is that this subwoofer requires an additional amp. This is relatively normal for modern-day subs, especially the best 8” shallow mount subwoofer. Manufacturers understand that audio lovers prefer to pick and choose their audio equipment. So if you’re looking for a built-in amplifier, you’ll have to look elsewhere. When shopping around for an amp, look for a power rating between 100 and 250 watts.

Pros

  • High-grade materials
  • Solid ported enclosure box
  • Ready to connect
  • Internal volume relative to external volume
  • Amazing JL Audio warranty

Cons

  • No built-in amp

3. Pioneer TS-SW2002D2

Best Cheap/Budget Option

Frequency Response/Range

20-200 Hz

Sensitivity

86 dB

Mounting Depth

2-⅝”

Power Output (RMS & Peak Rating)

RMS: 150W, Peak: 600W

Impedance

2 ohms

Warranty

1 year

The shallow-mounted Pioneer TS-SW2002D2 is the best cheap 8-inch subwoofer on this list of reviewed, rated, and compared subwoofers. Not only is it the top budget-friendly option, but it's also a powerful one. It features a peak power of 600 watts and 150 watts nominal power. This means that the sub can continuously handle 150 watts of power as you jam out to classic rock.

The shallow mounting depth of just 2-⅝” is much less than the typical 8” subwoofer. This means that you’ll be able to install this sub in nearly any location, even highly compact spaces. But don’t let the small size fool you. The subwoofer’s cone is larger than the average 8” model, and this oversized cone surface means that it is capable of moving more air. More air movement means louder and deeper bass - which is the entire point of investing in a subwoofer in the first place.

In addition to being small and loud, this piece of audio equipment is also sturdy. The manufacturer uses mica-injected molded resin, which is known for being durable as well as capable of producing accurate base. You most likely won’t need to use the Pioneer included warranty, but you should still register your Pioneer subwoofer to keep the warranty valid.

Just keep in mind that this product is only the subwoofer itself. You'll need to purchase the additional parts and pieces for optimal audio. Unlike the JL Audio sub, the Pioneer does not come with an enclosure case. If you do choose to purchase an enclosure case, Pioneer has one that is highly compatible with this subwoofer. The UD-SW200D down-firing shallow enclosure box is the perfect companion for the TS-SW2002D2.

Pros

  • Shallow compact design

Small vs Large Subwoofers

Some audio enthusiasts stand by their belief that large subwoofers are capable of producing a more powerful sound. Although there is some truth to this, modern audio technologies make it so that even small subs can handle a great deal of power - even small 8-inch subs. The perk of choosing a small sub vs. a large one is the added portability and lightweight size. 


Subwoofer Installation & Placement

Subwoofer performance has a lot to do with its placement. Acoustics have a significant impact on sound quality, so the first step in subwoofer installation is deciding on the perfect arrangement. For car audio, ideal placement is either in the trunk or beneath a seat. For home theater systems, you'll need to consider the size and shape of the room. 

Can I install my 8-inch subwoofers myself? This is a common question among first-time subwoofers. In most cases, the answer is yes. DIY subwoofer installation is possible, especially for small 8-inch subs. The most challenging installation step is connecting the receiver to the amplifier. 

You’ll need to follow the manufacturer’s specific instructions on how to do this. For extra help, refer to this helpful video tutorial by Crutchfield.

Subwoofer Adjustments for Optimal Sound

For optimal sound quality, you’ll need to make some adjustments to your subwoofer when you first get started. The common adjustment controls on modern subwoofers include things like crossover, volume, phase control, and equalizing. Most first-time subwoofer users struggle most with adjusting crossover, which is the frequency at which your subwoofer starts effectively play bass.

To properly adjust crossover, find your subwoofer's specifications on the frequency range. If the frequency range is between 80 and 180 Hz, set the crossover to 80Hz. Setting subwoofer volume can be another difficult adjustment. Too-high volume can lead to a warbled, buzzy, and downright awful sound. Volume will have to be adjusted based on your personal listening preferences.


Common Subwoofer Issues & Fixes

If your subwoofer isn't working properly, there's a good chance that it relates to the system's wiring. It probably has to do with a failed connection between the receiver and the amplifier or problems with the speaker wires. Luckily, this is a reasonably easy fix. Simply check to make sure that the wires are all connected as they should be.


Frequently Asked Questions

Are compact subs still effective in bass production?

Absolutely. Even small, 8-inch subwoofers are effective in producing high-quality bass. A subwoofer from a reputable manufacturer comes with a built-in amplifier that is highly effective when it comes to producing low frequencies.

Will putting my 8-inch subwoofer in the trunk affect the bass?

The placement of your new audio device has a lot to do with sound quality, especially for car subwoofers. Luckily, you can gain bass without losing space by placing your 8-inch subwoofer in the trunk. Sound quality will not be affected as long as you’re using the best 8-inch subwoofer for car audio.

Do I need to have an audio amp to power my 8-inch subwoofer?

This depends on whether you have chosen a subwoofer with a built-in amp or one that requires an amp addition. If you do need to purchase an audio amp separately, make sure to accurately match the amp with your subwoofer. 

Which type of enclosure should I get?

It is very unlikely that an 8-inch subwoofer will feature a ported enclosure. Ported enclosure types are more common for large subs. If you’re searching for a small subwoofer, the best choice is the sealed enclosure type.

What should I expect from an 8-inch subwoofer?

You might be surprised by how powerful an 8-inch subwoofer can be. If you opt for one of the models in the 8 subwoofer reviews above, expect to be wowed by sound quality, bass production, and portability.

What are the top subwoofer brands for 8-inch models?

There are several reputable audio equipment manufacturers to choose from, but in our eyes, the top brand for 8-inch models is Alphasonik. You might also consider JL Audio or Yamaha.


Conclusion

In our honest opinion, the best 8-inch subwoofer is the Alphasonik. It’s powerful with a peak power rating of 800 watts and an impressive frequency range of 35 to 500 hertz.

In addition to these high-performance features, the Alphasonik is extremely reasonable in price. For an all-in-one subwoofer system that comes with an enclosure box (the Alphasonik does not), you might consider the Yamaha powered subwoofer instead.
