Best Wood For Speaker Box

Have you ever wondered what is the best wood for a speaker box? Well, it really depends on what you are looking for. There’s not one type of wood that will be better than another.

Different woods have different audio characteristics. For example, some materials will be better with bass frequencies. Others are better set against higher octaves. This is what you want to consider when choosing which type of wood for your speaker box.

Best Wood for Speaker Box

1. MDF (medium-density fiberboard)

MDF is easy to work with and cuts easily. It comes in different thicknesses. The thicker the board, the harder it is to make curves with but it does make a stronger enclosure which means better sound quality. Usually, most people will go with 3/4″ MDF because you can get nice boxes without having to spend a lot of money. MDF is also very heavy, so make sure you have enough people to help you move the box.

Pros

• Dense –  thick boards are naturally more heavy duty
• Economical –  if you are running a small business, MDF is the least expensive option because you can get thicker pieces without breaking your budget
• Easy to cut –  doesn’t wear out saw blades as fast

Cons

• Paint can chip off easily
• Heavy – moving your enclosure around will be a chore if it’s thick enough. 3/4″ MDF is 40 lbs per 4×8 sheet, so plan accordingly
• MDF looks boring – the best wood for speaker box doesn’t have to be pretty

2. Baltic Birch Plywood

Baltic Birch is a type of plywood that has a thin layer of a birch on the top and bottom, which makes this an extremely strong piece of plywood. It’s not heavy, so having 1/2″ Baltic Birch will have less weight to deal with than MDF or other types of wood.

The high quality of the Baltic birch as it relates to a speaker’s output and performance has been proved.  This is due to the fact that, like plywood, it’s made up of multiple layers which adds strength. Each layer acts as extra cushioning that reduces vibration and increases sound quality.

Pros

• Beautiful – you can get Baltic Birch in many different styles from light birch to dark walnut
• Lightweight – if you are short on people to help you move your enclosure around, go with 1/2″ Baltic Birch
• Strong – being lightweight doesn’t mean being weak. This plywood box will perform just as well as MDF.

Cons

• Expensive –  Baltic Birch is more expensive than MDF, but still cheaper than other types of wood
• Can chip – it’s not as durable as MDF or even pine
• Not that easy to work with – you will need a table saw and a jigsaw

3. Pine

Pine is a great beginner wood to use for a speaker box. It’s the least expensive of any type of wood you will find, and it’s also very easy to work with. A novice carpenter can make functional pine sound enclosures if they have the right tools.

It’s available in a variety of thicknesses, but it isn’t exactly the best solution for increasing resonance and tones, which means you won’t get ideal sound quality. But if you are on a tight budget or just want to build your first speaker box, then pine is the best wood for a speaker box.

Pros

• Inexpensive – cheaper than Baltic Birch and MDF, but it’s still pretty affordable –  only slightly more expensive than plywood
• Easy to cut – won’t wear out jigsaw blades as fast as MDF would
• Lightweight – easy to move around with 1/2″ pine board being about 25 lbs per 4×8 sheet

Cons

• Cannot curve well – so don’t plan on making any curves unless you have professional tools for cutting the angles
• Easily dented when screwing in screws
• Not that strong –  pine is soft and weak. If you want an enclosure that you don’t have to worry about being fragile or breaking, steer clear from pine.

4. Oakwood 

Oak is the most expensive of all the wood you can use for speaker box construction. Oak looks very nice and it’s not any heavier than Baltic Birch plywood. Oak is typically used in higher-quality speakers because of its fine grain patterns, which makes it very attractive to look at. As for sound quality, using oak has been shown to reduce resonance and tones.

Pros

• Beautiful – beautiful grain patterns that will make your enclosure stand out among others
• Tougher than MDF – oak is hardwood, so it’ll hold up better to wear and tear
• Treatable

Cons

• Most expensive type of board – can’t just buy one piece for a good price unless that price includes a handful of pieces
• Dents easier than other woods – screwing in screws and nailing it down can cause dings and damage to the wood

5. Marine-grade Plywood

HDF is marine-grade plywood that has been treated with water protectants to prevent decay. This type of board is only a little better than MDF when it comes to sound quality, but there are some benefits that come along with it. The dampening effect of the HDF prevents ringing and improves the woofer’s performance while also being less dense or heavy than MDF while still being strong enough to handle car doors slamming on it.

Pros

• Inexpensive – similar price as Baltic Birch Plywood and 1/2″ pine so you won’t have to break the bank to get started building your enclosure
• Lightweight – even lighter than the other types of listed here, making it easy to move around by yourself
• Dampens sound well – preventing ringing and improving the woofer’s performance

Cons

• Not that durable – will wear out fast if you don’t take care of it, chips and scratches easy
• Easy to dent when hammering in screws or nails
• Strength depends on thickness – thicker HDF (3mm) is more durable than thinner HDF (2.4 mm)

What To Consider When Choosing a Wooden Speaker Box

Weight

How heavy are other speaker enclosures made with the same wood? 1/2″ pine is lightest while oak and HDF are light but stronger

Budget

Look at the cost per foot/inch if you want to buy multiple boards of the same type of wood for a good price

Sound quality

No matter which type of board you choose, none of them have better sound than another, just different qualities that work well for certain types of speakers. The best way to get great sound quality is through your choice of woofers and tweeters

Open or Closed Back Boxes

Open – sound waves are allowed to bounce back through the opening of the box, which creates a more natural sound

Closed – unneeded air is blocked from leaving the enclosure, which makes it harder for bass to reverberate and reduces standing waves

Warping or Denting

If you’re going to use a certain type of board, consider what you can do to prevent it from warping or denting easily.

Ease Of Use

Think about how easy or hard it is to move around, screw in screws and nails, make curved shapes, etc.

Durability

Consider the life expectancy of the type of wood you’re going to use. Baltic Birch can last a while longer while MDF falls apart easily over time if not taken care of properly.

Conclusion

While all wood has many of the same acoustic properties, there are some that have better resonance than others. Ultimately it really depends on what you’re looking for in your speaker box. We can help you make a decision about which type of wood to use based on the sound quality and durability needed. Knowing this will help narrow down which type of wood would be better suited for choosing the best wood for the speaker box.
