This 12-inch shallow mount subwoofer that loaded with technology. For one, this subwoofer comes with Pioneer’s Air Suspension Control System technology. While most subs use a spider design to keep the coil aligned, the TS-SW3002S4 seals air into a pocket between the main cone and the internal drive cone. This pocket creates an “air suspension system” that lets the subwoofer perform at its optimal level with much less amount of enclosure volume.

The rear of this shallow mount subwoofer has a stamped metal fin-shaped basket that directs the airflow sideways, therefore eliminating the “loading effect” when a sub is installed to close to a wall. This is the reason behind its unmatchable sound quality and unlike the above product, it can handle up to 1500 watts.

The cone structure of this sub is reinforced with MICA injected molded resin and apart from increased durability, it allows for accurate bass.

What to Look for When Buying a Shallow Mount Subwoofer for Trucks

Shallow mount subwoofers are great when it comes to maintaining outstanding audio quality while taking up as little space as possible. They also are pretty expensive, therefore it’s important to spend a few extra minutes to familiarize yourself with their specifications and arm yourself with the knowledge to make the best purchase possible.

Here’s everything you need to know about shallow mount subwoofers for trucks:

High-Quality Cone

The cone is the only moving part of the shallow mount subwoofer and is one of the most important parts of the subwoofer. Cones are made from various materials, therefore not every material is of equal quality.

There are five different cone material types:

1. Polypropylene

This is the most popular material for shallow mount subwoofer cones because it’s easy to manufacture, very lightweight and more durable than paper. Polypropylene is good at preventing mold and mildew growth, which would damage the cone. 

2. Treated Paper

It’s not surprising that paper is one of the most popular materials for shallow mount subwoofer cones. Paper is lightweight, which is why it has the fastest response time, and inexpensive. However, treated paper cones are coated with carbon, CSX, fiber, Kevlar, and polyglass to be more durable.

3. Magnesium and Aluminum

While these materials are commonly used in various audio parts, they are best utilized in subwoofers. Aluminum and Magnesium tend to produce a high-pitched resonance, but once these materials are used in shallow mount subwoofers as cones, the high pitch resonance is drowned out by the low-frequency sound waves.

4. Kevlar

Kevlar is used in bullet-proof vests and textile motorcycle gear, so it’s an extremely durable material. Apart from its crazy durability, Kevlar is also a lightweight material, which makes it a great material for subwoofer cones. Kevlar doesn’t stretch; therefore, it keeps its shape under pressure and allows for a better sound displacement.

5. Carbon Fiber

Carbon fiber is the ultimate shallow mount subwoofer cone material. It combines all the positive features of the above materials. It allows for maximum durability and high output levels thanks to its extreme toughness and flexibility.


Size is one of the most important factors that influence the sound quality of the shallow mount subwoofer.

An 8” shallow mount subwoofer will provide a responsive light and soft bass to your trucks sound system, while a 10” unit will bring bigger and more noticeable bass.

12” is the most popular size for shallow mount subwoofers for trucks, as it has the perfect balance of small size and big bass. They handle a lot of frequencies and are the perfect choice for truck owners that appreciate quality bass.

15” shallow mount subwoofers give the deepest bass possible. One downside to such big shallow mount subwoofers is that they are less responsive to fast music.


You want to be blasting your shallow mount subwoofer for years to come, so make sure the cone of your shallow mount subwoofer of choice is made of good quality materials. In addition to durable cones, stitched tinsel leads are the way to go.

Also, remember the old saying “cheap man pays twice”? It especially applies to shallow mount subwoofers. 

Shallow Mount Subwoofer Specifications Explained

Electrical specifications can get really confusing at times, but they are the best way to determine the quality of a shallow mount subwoofer.

Power Rating

This is a good indicator of how powerful the shallow mount subwoofer is. Make sure your trucks amplifier can handle your subwoofer.


Impedance shows how much resistance to electrical current the subwoofer has and determines how easily the subwoofer can turn electrical signals into sound waves. Automotive subwoofers only come in a 2omh and 4ohm impedance.


A shallow mount subwoofer with lower impedance (resistance) is able to produce a louder sound when compared to higher 4ohm impedance subs. However, 2ohm impedance subwoofers tend to produce poorer quality sound due to their power consumption.


A higher ohm impedance subwoofer uses less energy and lasts longer than 2ohm impedance subwoofers. When it comes to sound quality, most people tend to agree that even though 4ohm subwoofers aren’t as loud, they produce a better quality sound.

Now, these differences in sound quality are very small, and, in most cases, you should go for the same impedance as your truck’s amp.


Sensitivity is a measure of how loud a subwoofer is. This is determined by measuring the amount of electrical power that is required to produce sound at a certain volume level.

If you’re using a low power amp, a higher sensitivity shallow mount sub would compensate for the low power amp and provide higher volume sound.

If your truck has a powerful amp, a low sensitivity sub is definitely the way to go.

Number of Voice Coils

Subwoofers come with either single or dual voice coils. Dual voice coils can be wired in series, parallel, or independently – each configuration has its benefits. For most cases, a single voice coil shallow mount subwoofer is more than enough, however, if you’re an advanced audio enthusiast you might want more flexibility from your subwoofer, in such case, dual voice coils are the way to go.
