Best 12-Inch Subwoofer Buying Guide

This guide will examine some of the main features you should consider when purchasing.

Power rating

The first thing you’ll need to consider when choosing a subwoofer is how much power it can handle. You’ll want to ensure that the subwoofer can handle the amount of power your amplifier can deliver.

Look at the manufacturer’s specifications to see how much power your amplifier can deliver. Most subwoofers will have a power rating expressed in watts RMS (root mean squared).

The RMS power rating is the power the subwoofer can handle continuously. It’s important to note that the RMS power rating differs from the peak power rating.

The peak power rating is the power the subwoofer can handle for short bursts. For example, if the RMS power rating of a subwoofer is 200 watts, the peak power rating might be 400 watts.

When choosing a subwoofer, it’s generally best to choose one with an RMS power rating similar to the amplifier.

If you are unsure about the power output of your subwoofer, you should consult with a car audio specialist.

Frequency Response

Another important consideration when choosing a subwoofer is the frequency response. The response is the subwoofer’s capability to produce a range of frequencies.

The average response for subwoofers is 20 Hz to 200 Hz. This means that they can reproduce frequencies in the low bass range.

Some subwoofers have a higher response, which means they can reproduce frequencies in the mid-bass range. These types of subwoofers are sometimes referred to as midrange subwoofers.

If you want to reproduce frequencies in the high bass range, you’ll need a subwoofer with a high-pass filter. A high-pass filter is a device that allows only high frequencies to pass through while blocking low frequencies.


A car subwoofer’s sensitivity denotes how much noise the speaker creates from a set amount of power. A higher sensitivity means that the subwoofer will be louder. Most car subwoofers have a sensitivity of 80 dB to 95 dB.


The impedance is how much electrical resistance there is in a circuit. The lower the impedance, the easier it will be for an amplifier to drive the speaker. Most car subwoofers have an impedance of 4 ohms to 8 ohms.

Number Of Voice Coils

The number of voice coils on a subwoofer determines how many wires are wrapped around the cone. More coils mean more surface area for the cone to move, which means more power handling.


Next, you need to consider the size of the subwoofer. The size is measured in inches, indicating the speaker’s diameter.

Choosing a subwoofer that is the right size for your car is essential. You will not need a large subwoofer if you have a small car. However, you will need a bigger subwoofer if you have a large vehicle.

The size of the subwoofer also determines the amount of bass it can produce. A larger subwoofer can produce more bass than a smaller one.

Which Is The Best Subwoofer For Deep Bass?

The MTX Audio TNE212D is definitely the one you should consider. This 12″ Subwoofer offers an impressive 1200 watts of power, allowing you to enjoy deep bass sound with minimal distortion.  It features a 2-ohm dual voice coil for superior sound quality and a Kevlar reinforced cone for maximum durability.

Is One 12 Inch Subwoofer Enough?

If you have primary speakers and want an extra bit of “oomph” in the bass, then a single 12 inch subwoofer may be enough.  However, if you’re looking for earth-shattering bass or actual home theater experience, consider adding an additional subwoofer or even a dedicated subwoofer amplifier. Additionally, if you’re hoping to get a balanced sound in your car audio system, you should generally have at least two subs.

What Size Of Enclosure Is Needed For A 12-Inch Subwoofer?

The size of the enclosure needed for a 12 inch subwoofers will depend on several factors, such as the efficiency of the Subwoofer and the desired sound output. 
Generally speaking, look for an enclosure with at least 1.25 to 1.75 cubic feet. However, if you want to achieve maximum performance from your Subwoofer, a larger enclosure may be necessary. It is best to consult with an audio expert or the manufacturer of your Subwoofer for the most accurate information.

Which Company Makes The Best Subwoofer?

That depends on your specific needs and budget. Some of the most popular subwoofer brands include Pioneer, Rockford Fosgate, Skar Audio, Alpine, Kicker, and MTX.  Each brand has unique features that make it a better choice for some customers. However, regardless of which brand you choose, ensuring your Subwoofer is appropriately installed and tuned to get the most out of it is important.

Bottom Line – Best 12-Inch Subwoofers

In conclusion, both the Rockford Fosgate P3D4 and MTX Audio TNE212D are excellent choices for 12 inch subwoofers. The Rockford Fosgate is perfect for anyone looking for a high-quality and powerful sound system, while the MTX Audio is ideal for those who need deep bass and a stylish design.
