Best Wood for Speaker Box

1. Baltic Birch Plywood

According to our experts, Baltic Birch Plywood is one of the best woods for speaker box due to its varying thickness.

Baltic Birch is dense and known for its rigidity. Acoustics-wise, it offers exceptional performance that can only be rivaled by just a few other wood types. 

Also, it is durable and will last as long as your speakers. And if you are frequently on a bumpy road, you can trust Baltic Birch Plywood to protect your audio system.

It’s thick, and the sheets are uniform. This makes it less prone to warping and resistant to environmental factors like rain and sunlight. 

Pros

  • Quality sound
  • Less susceptible to warping
  • Durable
  • Offers optimal sound system protection
  • Delivers exceptional performance

Cons

  • Quite expensive
  • Slightly heavy

2. Medium-Density Fiberboard (MDF)

MDF is another great option for subwoofer boxes. Getting a speaker constructed with medium density sheets or using MDF to build a subwoofer box will give you natural undistorted sound.

Vibrations are among the catalysts of distortions, and with MDF, you won’t encounter such problems. MDF is thick and denser than most materials in the market, which helps to keep vibrations and mechanical pressures at bay.

Since MDF is relatively thick, your speakers are protected, even on bumpy roads. This makes MDF an excellent subwoofer enclosure that will keep your mind at ease.

Pros

  • Easy to cut
  • Produces high-quality sounds
  • Offers optimal protection
  • Keeps vibrations at bay
  • Durable

Cons

  • Slightly expensive
  • Quite heavy

3. Marine-grade Plywood

This is another excellent plywood option for a speaker. Initially, Marine-grade Plywood was used in building boats, hence the name marine. However, it is now used to make speaker boxes. 

Marine-grade is known for its resistance to environmental factors because of its higher density. This feature prevents resonance issues [1], allowing you to hear the best natural sound.

Though it’s lightweight, the sheets ensure you have the most stable tone and the best bass quality.  However, it’s not as solid as you would expect because the glue used in joining the sheets absorbs water.

Pros

  • Improved stability
  • Resistant to environmental factors
  • Lightweight
  • Improves the quality of the sound
  • Eliminates resonance issues

Cons

  • Less durable
  • Less solid wood

4. Pine

Pine is another thick material that’s good for speaker boxes. It comes in one or more sheets of varying durability, although it may not be an excellent option for improving resonance and tones.

You can choose to buy the standard pine, which is more natural-looking than the pine. However, both pines come at affordable prices.

Pine can easily be treated with paints to enhance its resistance. This makes it suitable for speaker boxes and prevents the sheets from decaying or rotting away. 

Additionally, pine material is soft and more sound-absorbent compared to some plywoods.

Pros

  • Absorbs sound
  • Resistant to rot and decay
  • Cost-effective
  • Durable

Cons

  • Results in increased knots
  • Offers less performance

5. Oak

If there’s one thing our experts admire about oak materials, it’s their appealing designs, which have become a popular choice for a speaker box.

Oakwood is a rich brown-colored sheet that comes in varying thicknesses. It is cut from an oak tree and is commonly used for making wood furniture, such as cabinets, due to its strength and uniformity. 

Oak plywood is soft, long-lasting, and has greater resistance to environmental factors. Due to its uniformity, you will experience less warping in the box of the speaker. 

Also, it is treatable, and you can choose to customize it according to your desire. Overall, it’s an excellent material for aesthetic purposes rather than its tone performance.

Pros

  • Long-lasting material
  • Offers greater resistance to sunlight and water
  • Customizable
  • Treatable

Cons

  • Quite heavy
  • Less solid

What to Consider Before Choosing the Wood for Your DIY Speaker Box

Choosing the best wood for your speaker box depends on a variety of factors. Since a speaker box impacts the quality of tones and their durability, you should, therefore, consider these factors:

Tone and Resonance

Most users want their speakers to produce a sound quality that’s as clear as possible without vibrations or distortions.

It’s a vital component in considering speaker boxes, especially when you have spent about $10,000 for a set of floorstanding speakers. You wouldn’t want to mess the clarity and tone of high-end audio gadgets like that.

In that case, you should opt for denser woods like Medium Density and Baltic Birch plywood. They make the subwoofer tone better and more precise than other types.

Warping

Warping is a distortion in woods as a result of moisture and temperature, changing parts of the wood. Warping occurs in non-uniform natural woods. Therefore, when constructing a subwoofer, you should go for a wood that’s less likely to warp.
