Best Subwoofer Box- Top 5 Reviews and Buying Guide

Your car audio setup may not be complete without investing in a subwoofer. Subwoofers deliver deep bass in any sound system. It can be very exciting to feel deep and chest-pounding bass, especially if you’re a bass enthusiast. Besides, a subwoofer improves the sound quality of your car sound system regardless of the music genre you’re listening to.

However, maximizing the performance of your car subwoofer requires adding a subwoofer box. While a subwoofer can deliver a specific amount of bass, it can’t output the best bass quality without a properly constructed subwoofer box. Essentially, the sound coming from the back of the subwoofer cone cancels out the sound coming from the front of the subwoofer cone. As a result, you won’t get the best bass output. A subwoofer box prevents this problem by ensuring that the sound coming from the front of the cone won’t be canceled out, thereby enhancing the bass output.

Also, a subwoofer tends to vibrate a lot. By mounting it directly on a car panel, it’ll vibrate a lot when playing music loudly. The vibrations may cause a lot of noise that’ll interfere with your listening experience. Also, the vibrations can damage the subwoofer. Enclosing a subwoofer with a subwoofer box, assists in containing the vibrations, thereby reducing noise and preventing the subwoofer from getting damaged.

Although you can build your own subwoofer enclosure, getting the size and design right can be a big challenge. Luckily enough, you can buy a factory-manufactured subwoofer box. However, you need to choose the best subwoofer box for the best performance. Here’s a guide on how to choose the best subwoofer enclosure for your car.

Top Features

  • Screw-down terminal cups- The subwoofer enclosure comes with screw-down terminal cups. These terminal cups make it easier to hook speaker cables than spring post terminals.

This E10S Pro-Series 10 subwoofer enclosure is yet another great sub box from Atrend Bbox. It’s specially designed with affordability in mind. In fact, it’s the most affordable subwoofer enclosure in our reviews. However, it has the least mounting depth and airspace in our list of reviews.

It’s designed for attaching 10-inch subwoofers, just like our third pick, the BBox E10SV Single 10″ Vented Carpeted Subwoofer Enclosure. However, this Atrend Bbox E10S Pro-Series 10 is the only sealed subwoofer box in our review. It’s a perfect choice for anyone looking for a sealed subwoofer box.

  • Tight bass- The enclosure features an airspace of 0.67 cubic feet. Although this airspace may sound minimal, it’s advantageous in that it allows for the reproduction of accurate bass. The reason behind this is that the sealed enclosure design keeps air trapped within the enclosure. Thus, the air works as a shock absorber that allows the subwoofer driver to move air in a controlled way, thereby delivering accurate bass.
  • Airtight precision- The panels are attached to each other using a special Miter and Dado design. The design ensures that all the panels fit together with high precision. Consequently, the enclosure allows for airtight precision for noiseless and rattle-free performance.
  • Special wood glue- The MDF panels making up the enclosure are joined together using special wood glue. This glue creates an airtight seal between the panels. Also, the internal joints are completely glued together. The glue seals the joints in a way that guarantees zero air leak.
  • Premium carpeting- Another great feature of this subwoofer enclosure is its premium quality carpeting. The carpeting wraps the entire exterior surface of the panels. The carpeting comes in a charcoal grey color to match with almost any car interior.

Factors to Consider When Buying a Subwoofer Box

Although subwoofer boxes are designed to enhance the bass output of your subwoofer, they differ in terms of design and performance. Thus, it’ll help to know the considerations to make when choosing a subwoofer box to stand a better chance of buying the best subwoofer box. Here’re the main factors to consider when shopping for a subwoofer box.

1. Type of Subwoofer Box

Subwoofer boxes are available in three main categories including ported boxes, sealed boxes, and bandpass boxes. To start with, a ported subwoofer box has a hole on the side or at the bottom. This hole is known as a port. The port allows some air to move out of the enclosure when the subwoofer cone moves air back and forth. As a result, there’s equalized air pressure on the front and back of the subwoofer. As a result, the subwoofer driver doesn’t work very hard, thereby reducing power requirements. Also, a ported box allows for loud bass output. However, the port makes the bass output less accurate. The design behind a ported box requires a larger subwoofer box, meaning that it takes up more space in a car.

On the other hand, a sealed subwoofer box is fully enclosed. Thus, it doesn’t allow air to get into or out of the enclosure when the subwoofer driver moves back and forth. As a result, there is tight air pressure within the subwoofer box, thereby resulting in tight bass output. However, the bass output is not as loud as that of a ported enclosure. Also, the high pressure within the enclosure means that the subwoofer driver works harder, thereby demanding more power from the amplifier. The design behind a sealed subwoofer box allows for the construction of a compact box, thereby taking less space in a car.

Bandpass subwoofer boxes feature a design that combines both ported and sealed subwoofer boxes. In this design, there’re two air chambers in the enclosure. One of the chambers is sealed and houses the subwoofer. The other air chamber is ported and is set in front of the chamber housing the subwoofer. This design allows for enhanced bass boost, louder bass, and enhanced efficiency.

Considering the differences between these types of subwoofer boxes, anyone whose car has limited space should consider investing in a sealed subwoofer box. Also, if you love tight bass, a sealed subwoofer box would be your best bet. On the other hand, if you prefer loud bass or your car is spacious, then consider investing in either a ported or bandpass subwoofer box.

2. Size

Subwoofer boxes are available in a wide range of sizes, with the most common sizes being 8-inch, 10-inch, 12-inch, and 15-inch subwoofer boxes. 8-inch subwoofer boxes are ideal for small cars due to their small and compact design. 10-inch boxes are ideal for most family cars. 12-inch boxes are perfect for luxury cars while 15-inch boxes are ideal for trucks. Thus, choose a subwoofer box that can fit in the available car space.

3. Construction Material and Build Quality

Most subwoofer boxes are made of materials such as MDF, fiberglass, standard wood, and plywood. Ensure the material used is of premium quality such that it doesn’t cause noise or distortion. Also, the panels should be sturdy to ensure they don’t vibrate or flex. Additionally, the materials used should be of top quality for enhanced longevity.

The subwoofer enclosure should be well-built. The joints where the panels meet should be properly sealed to ensure they don’t come apart and to prevent air from flowing through the joints. The enclosure should be structurally sound for enhanced longevity,

4. Mounting Depth

Ensure the subwoofer box you’re choosing has sufficient mounting depth for your subwoofer. The mounting depth of the box should be more than the mounting depth of your subwoofer. This means that there should be a sufficient gap between the back panel of the subwoofer box and the subwoofer itself.

5. Airspace

The airspace of a subwoofer box is the amount of space within an enclosure in cubic feet. Essentially, more airspace delivers deeper bass while less airspace delivers tighter bass. Ensure the airspace of the subwoofer enclosure is sufficient for the specific subwoofer you want to enclose. Check with the manufacturer of your subwoofer for details regarding the recommended airspace.

6. Aesthetics

Some enclosures have a spray finish while others are carpeted. Just ensure that the finish and design will complement your car interior décor. It should match with the existing décor and have an appealing look, especially when installed in a more visible location.
