Various Types of Subwoofers


The powered subwoofer has an amplifier built into the enclosure, making it suitable for smaller rooms. Subwoofers with decent bass frequency and sound quality; However, their compact enclosure hinders them from releasing hard-hitting high-quality and deep bass tones. Their size and easy installation are beneficial, especially in small spaces.


A component subwoofer is made up of many parts that are designed for audiophiles looking to modify their audio system. It is possible to select the type amp, enclosure, and other components you wish to add. Technical expertise is required when a subwoofer can be customized to fit your requirements. A non-component subwoofer has everything you need in one enclosure. This kind of subwoofer is designed for those who don’t wish to spend too much time on installation.


An enclosed subwoofer is mounted within an enclosure specifically designed to house it. They do not come with amplifiers, which means you’ll have to buy one separately. There are fewer enclosed subwoofers available on the market than the other options. However, they’re a good option if you’re looking for an easy way to upgrade your audio system.


Subwoofers for vehicles are hidden at various places inside your car, truck, or even an SUV, like the door. It’s a good option if you’re short on space or would like to place the subwoofer away from view in a place. They are typically matched to your car’s interior and are mounted inside an enclosure. But, they do not produce an enormous, loud bass sound compared to bigger subwoofers.

Benefits of Subwoofer

Enhance your audio system’s bass

The most powerful subwoofer of 8 inches will improve your music more than the standard car speakers. A subwoofer of 8 inches will provide more power and power, regardless of the setting.

Make sure you have a car battery

Smaller subwoofers typically don’t draw enough power. Therefore, they’re less likely your vehicle’s battery is a bigger sub. However, they’ll still give amazing audio.

Secure your factory speakers

If you enjoy the sound of a lot of bass, it could damage the original speakers, which weren’t made to handle large amounts of sound. The speakers that come with the car may break or split because they’re usually cardboard and plastic.

Power a five-channel amplifier

Small subwoofers can be configured to be used using a five-channel amplifier. The more powerful subs usually require a monoblock amplifier and an additional amplifier for the subwoofers.

8-inch Subwoofer Buyers Guide

Frequency Response

Frequency response is an audible periodic vibration that is measured in hertz. More pronounced signals are associated with higher frequency. Most listeners can detect tones in the range of 20 to 20 Hz.

Subwoofers’ capacities differ, but they generally generate frequencies ranging from up to 200Hz. Therefore, it is suggested to limit the frequency range of a subwoofer’s frequency from 100 Hz to 100 Hz by using a crossing filter.

RMS power rating

The RMS power refers to the power output that the subwoofer can handle. This means they’ll generate more power if they can handle more power, usually assisted through an amplifier.

Quality of sound

The quality of sound does not depend entirely on subwoofers. However, it is essential to think about dimensions, power, frequency, and size range. The enclosure type, the location of the sub within the vehicle, and the kind of amplifier you select can significantly affect the performance.

Mounting depth

Be sure to follow the manufacturer’s specifications for the size of your enclosure, especially if you do not have a lot of space. The box’s volume will show the dimensions of your enclosure to ensure proper performance. Ideally, you will determine the minimum thickness of your enclosure with the addition of 2 inches depth of the subwoofer.

Single Vs. Double Voice Coils

Single voice coils can be helpful when you need a quick and easy upgrade to audio equipment. Dual voice coils provide the flexibility of adding additional outputs for sound. If you are interested in customizing your stereo to achieve the best sound, you should consider two voice coils.


Every subwoofer is equipped with a wattage rating which shows how much power it can handle. It is important to remember this rating was created only for the highest performance. A subwoofer operating at its maximum rating for a prolonged period may eventually become overheated and fail. Take a look at what is known as the roots mean square (RMS) to find out how much power it can handle consistently.

Sensitivity Rate

To figure out the power of a subwoofer, you must look at the sensitivity and their power rating. A sub with a greater sensitivity can provide the same sound quality but with less power than one with a lower sensitivity.

Component vs Non-component


Component speakers have distinct crossovers, tweeters, and woofers to produce a big sound. As opposed to non-component systems, you will need to put in time and effort to install these speakers.

Quality of sound

A handful of subtweets, tweeters, and other devices can produce an unmistakable sound.

Non-component speakers cannot produce a decent bass and are not of good quality.

Power handling capacity

One of the significant differences between the speakers is that the latter was designed to handle 250 power at peak and 110 Watts in RMS.

Enclosure type

A sturdy, well-constructed enclosure allows subwoofers to have the best performance. Without it, they cannot produce great sound as the bass from the back blocks out the bass frequencies that come from the front of the speaker.

The range of enclosures:

  • Sealed boxes to provide precise, deep bass
  • Boxes with ports to increase the bass response
  • Bandpass boxes to maximize punch or additional volume
  • Free-air woofers that offer an isolated sound from the rear of the unit
  • The underseat enclosure is for cars that do not have trunk space

FAQs 8 Inch Subwoofers

Does the type of enclosure affect the results?

The enclosure type dramatically influences the sound quality that the bass produces. The majority of enclosed subwoofers are placed within pre-mounted enclosures. Think about ported and bandpass enclosures if you’re looking for more volume. If you’re looking for deep low frequencies, consider the sub that is sealed in a box.

Does the material of the subwoofer cone impact the results?

Subwoofer cones are diverse in their design ranging from paper to composites. Paper is less durable. However, it’s light and offers a quick response. All in all, the types of materials work perfectly and provide equally excellent audio.

Does a subwoofer require an AMP?

A powered subwoofer usually includes an amplifier and speaker inside the enclosure. They are ideal for those with a small automobile and don’t have much room for an amplifier and speaker system.
