If you are in the market for a new 12-inch subwoofer, then you have come to the right place. In this guide, we will provide you with everything that you need to know before making your big purchase. A subwoofer is a device that is added to your car or home audio setup that produces the low frequencies needed to make great sound quality. A subwoofer produces the rumbling bass sounds that everyone likes to hear.
How Subwoofers Work
The deep bass sounds that are present in most types of music or movies need an outlet of a certain frequency to be heard by the user. This is where a subwoofer comes into play. Subwoofers are connected to the receiver, which sends low-frequency signals via electrical current to the subwoofer. The subwoofer amplifies the current and transmits it as sound in the air.
Types of 12-Inch Subwoofer Speakers
Benefits of 12-Inch Subwoofers
Enhancing your sound experience in your home or car can change the way you feel about that space. There are many benefits of adding a 12-inch subwoofer to your audio setup. One of the most important features about all around, high-quality sound is the ability to distinguish the low-frequency tones. Adding a 12-inch subwoofer will drastically change the amount of bass that you hear in your car.
Another positive feature of subwoofers is that they reduce the distortion in the sound system. If you use a standard speaker, the bass can sound distorted since it is not made to transmit low frequencies.
Choosing a High Quality 12-Inch Subwoofer
Power Output/Volume/Sound Quality
This factor is an important one when setting up an audio system. It is just as important when choosing a subwoofer. The more power a sub has, the more bass and sound it can produce. Depending on your setup, you also need to consider how loud a speaker can be turned up before it becomes distorted.
If you are going to invest in a 12-inch subwoofer, you want to be sure that you get the best frequency range available. The frequency response of a sub is measured by how well it can produce a range of low-pitched sounds. A great subwoofer will have a range of 20 to 200 Hz. Anything lower than this and the human ear will have a difficult time hearing it.
One critical factor to consider is the voice coil resistance in your sub. This is also known as the impedance. Lower impedance means that the amplifier will be better able to supply power to the sub. You should consider the amplifier power before wiring your subwoofers. Most subwoofers will be able to handle anywhere from 2 to 8 ohms.
Every subwoofer speaker is capable of producing a certain level of sound. The higher the sensitivity rating of a sub, the louder it will be at a specific wattage. This is important to consider if you want your sub to produce high volumes such as in large rooms or for big parties.
Subwoofers come in all shapes and sizes, and placing them is vital in how well your audio setup will sound. Many subwoofers come in enclosures, where they can be placed on a shelf in your home theater system. For your car, subwoofers come in various sizes and are generally placed in the trunk.
There are two types of models in this category, single and dual. In general, neither one is necessarily better than the other. The model that you choose will depend on how many watts your amplifier is capable of producing. You can either feed the wires into two subs or one.
Wired or Wireless/Ease of Installation
There are many different options when it comes to setting up your speaker system. Wireless speakers can be moved around to many different rooms. They are also easier to set up since they have fewer connection points. Wired speakers are ideal for audiophiles who want the truest sound possible. They are also easier to implement into a system and keep in place.
Cone Size and Dimensions
One thing to keep in mind is where you will be placing your subwoofers. You may have limited space in your car, or home and the cone size and dimensions will affect this placement. In this guide, we are focused on 12-inch subwoofers, so make sure you have the space allotted.
Many subwoofers come with accessories, which is always a bonus. They may include features such as extra speaker wire, remotes, or elements that will enhance the bass of the subs. If you are searching for specific special features, check out the spec sheet of the sub you want to purchase.
There are generally two types of boxes that subwoofers will sit in. There is a sealed or ported/vented sub box. You can buy the box separately, or it may come with the speakers that you buy. The ported or vented sub box design typically handles distortion better than the sealed enclosure type.
Most subwoofers come with a warranty package when you purchase them. You should check with the manufacturer to see what kind of warranty they offer. Subwoofers are also durable if you make sure to keep them clean. You should make sure the air can flow freely through the coils so that the speakers will last for a long time.

Sealed vs Ported Enclosure
There are a couple of different kinds of subwoofers that you will need to take a look at when you decide to make a purchase. The first type is called sealed enclosure systems. This model generally holds the speakers in place in a sealed and completely enclosed box. It usually is better for compact form factors.
The other model is a ported enclosure model. It has a vented design that has better airflow. This type is generally better at displacing sound, so it is great for larger rooms.
12-Inch vs 10-Inch Subwoofer
The size of the driver does not always matter when it comes to buying a new subwoofer. The larger drivers may produce more sound and louder, but they do not always sound better than a smaller one. Usually, a 12-inch subwoofer will have a bit more bass response and clarity than a 10-inch model. You also need to decide how much space you will have in your car.
Now that you have your new purchase, you are going to want to know how to set it up. The first step is to ensure that you have a location to place the subwoofer. If it is going to be in your car, then you will want to place it at the back. This will give you the best sound. You need to put the speakers into an enclosure system unless it comes with one.
Then, you will need to place the enclosure system into the car. The subwoofers will also need to be powered by an amplifier. If you plan to place your speakers in your home theater, it will be much easier. You simply place the speakers near your sound source and plug it in.
Subwoofer Adjustments for Optimal Sound
Once you get your subwoofers in the correct place, you will want to make sure that all of the key features are set up to make the sound perfect. After placement, the next important adjustment will be the connections. Make sure that all cables are properly connected.
The next adjustments that should be made are the crossover, volume, phase, and equalizer. These adjustments should be made according to your speaker setup. The crossover should be adjusted between 40 - 120 Hz depending on the size of your speaker. The phase is a toggle switch that will be adjusted according to your other speakers.
Common Subwoofer Issues and Fixes
Although your model should be durable, there can be some problems that arise. For example, if you are getting too much feedback, you will need to adjust the frequency to a lower setting. Another common problem is that there may be interference from other devices. This can be a common problem if other devices are plugged in nearby. Simply adjust the cable connections to fix it.
If the speakers don’t match the subwoofer, then you should make sure that the watts and impedance lineup before plugging them in together.
Frequently Asked Questions
Which is better 2 ohms or 4 ohms sub?
