What Are Subwoofer Boxes Made Of?

Subwoofer boxes are usually made out of medium-density fiberboard (MDF) Which is regarded as the best. The majority of subwoofer boxes are made out of MDF. This is because it is cheap, easy to work with, and most importantly, acoustically inert. This means that it will not affect the sound quality of your subwoofer by adding any unwanted resonance or vibrations.


There are other types of wood used for making boxes, but MDF is popular due to its price point and ease of use.

Medium density fiberboard (MDF) is a type of engineered wood product that has been used in a wide variety of applications, including furniture, cabinets, and speaker enclosures. It’s made from wood fibers glued under high pressure using resins such as formaldehyde compounds like UF (urea-formaldehyde). The result is an incredibly dense material with good acoustic properties that can be cut into any shape you want without splitting or cracking like solid lumber would do when drilled too close to an edge.

Some subwoofer boxes are reinforced with fiberglass.

Subwoofer boxes are typically made of wood because it’s easy material to work with and offers a good balance between strength and weight. However, for additional durability, some subwoofer boxes are reinforced with fiberglass.

In general, fiberglass doesn’t affect the sound quality of the box. Rather, it increases its durability and strength by making it more resistant to vibration. The material is also waterproof, which is handy if you happen to spill something on your subwoofer box.

Some subwoofer boxes contain a vented port.

There are several different designs and materials used in the construction of subwoofer boxes. Some subwoofers work best in ported boxes, which contain a vent or port that allows air to move freely. The vented port allows for greater sound output and enhanced bass response. Many amps and speakers require special materials for the box so that you get the best sound possible from your equipment. This is why most manufacturers do not recommend making your own box without doing extensive research first.

Subwoofer boxes made out of polycarbonate

Polycarbonate is a type of plastic that is sometimes used to make subwoofer boxes. It’s a good choice for subwoofer boxes because it’s resistant to cracking and denting, making the box more likely to withstand the pressure exerted by you pumping up the bass.

Polycarbonate is also relatively lightweight and durable, so it can endure being tossed around in your trunk during road trips, as well as rough handling when you’re unloading or carrying your gear.

Subwoofer boxes made out of plywood

  • Plywood is the most common material used for subwoofer boxes. While it’s not as good of material as MDF, it’s more affordable and can still produce good sound quality.
  • Types of plywood commonly used are veneered plywood, hardwood plywood, and particleboard. These plywoods are graded based on their veneers—with AA being the best grade and D being the lowest quality grade.

Subwoofer boxes made out of Baltic Birch Plywood

Baltic Birch Plywood is a high-quality material to make subwoofer enclosures. It is slightly more expensive than other types of plywood. However, Baltic Birch Plywood has a smooth surface which makes it easy to glue together, as well as sand and finish.

The thickness of the Baltic Birch Plywood can vary, which can affect its resonance frequency, which in turn affects the sound quality of the subwoofer enclosure. Thicker plywood will have a higher resonance frequency than thinner plywood.

Although Baltic Birch Plywood may not be the most cost-effective material for building your subwoofer boxes, it does provide a nice surface that is easy to work with and looks very good when finished.

Subwoofer boxes made out of Particle Board

For the most part, subwoofer boxes are made from MDF. However, some subwoofer boxes may be made from less dense materials like particleboard. Particleboard is used in some speaker and subwoofer enclosures because it is a cheaper material than MDF. The particleboard is also not as stiff as MDF, which can result in the enclosure vibrating during the playback of the speaker. This is the reason why many subwoofer enclosures are made from thicker sheets of wood—to counteract this tendency to vibrate while playing bass-heavy music.

Some particleboard cabinet makers will use screws to secure their joints rather than adhesives or nail/staple guns because it’s more cost-effective and time-efficient for them to do so.

Subwoofers are amazingly powerful speakers that offer bass-heavy sound at high volumes, but finding the right one for your needs can be tricky. You need to know the materials used to construct a subwoofer box before you buy one because that will tell you how durable it is and whether or not it’s likely to produce good-quality bass.

When considering what to use to make your own custom ported subwoofer box, there are a few factors that you need to take into account. The type of material you use will determine the sound quality, durability, and overall cost of your project. Luckily, there are many subwoofer box materials available, with each having its own pros and cons listed above.
