Best Subwoofer Box Design For Deep Bass

For those who love drastically altering the sound produced by their speakers, getting the best subwoofer box design for deep bass is a matter to consider. You may have noticed how most speakers are built into wooden boxes.  You perhaps thought the wooden boxes were meant to improve the appearance of the speakers.  This is not the reason for the speaker enclosures.

Putting woofers into wooden boxes alters the quality of the sound they produce.  The box that you put the speaker in is critical.  Any cabinet would do for the speaker to produce sound, but you should try to achieve an optimal relationship between box and speaker.

Optimizing the relationship between the speaker and the box is the key to good quality bass.  Shaping the bass frequencies less than 200Hz is what determines the box type chosen.

There are a number of main types of boxes for optimal performance for different subwoofers.  For lovers of deep music, there is what would be considered the best subwoofer box design for deep bass.

Here below is a look at some types of subwoofer boxes.

Types of Subwoofer Enclosures for Getting the Best Bass Response

As stated previously, the type of sound you get from a subwoofer is determined by the woofer as well as the enclosure (box), it is in.  Without a box, the woofer can’t actually deliver full bass.  This is because the sound emanating from the front of the speaker can cancel out some of the low frequencies coming from the back.

Subwoofer boxes come in different sizes and are for different purposes.  Here are the three main types of subwoofer enclosures available in the market.

1. Sealed subwoofer enclosures. Designed for deep precise bass.

A sealed enclosure is an airtight box that houses your subwoofer.  When you want to produce a tight accurate bass, the sealed box is your best option.  What is produced has a deep bass extension, is not excessively boomy, which means it has a flat response, and has great power handling.  A sealed box requires plenty of power, therefore an amplifier with ample wattage is required for optimum performance.  This sealed enclosure is the best subwoofer box design for deep bass.

2. Ported subwoofer enclosures. Designed for forceful bass.

They require less wattage than the sealed boxes.  A ported enclosure uses a vent (also referred to as a port) for the reinforcement of low bass response.  It gives more output at any amplifier wattage than you would get from a sealed box.

When you have a ported box that is larger than a sealed box, it will deliver a deeper bass.  Ported boxes are preferred by some for music that is hard driving, such as rock and heavy metal.

3. Bandpass subwoofer enclosures. Designed for maximum slam.

This is a special type of ported box designed for maximum slam.  The box usually has two chambers, one ported and one sealed.  The subwoofer is mounted within this dual chambered box.  Sound waves come out from the ported side.  The sound emanating from the vent has a narrow frequency range and is extra loud.

Bandpass boxes are super efficient within this narrow frequency range.  Therefore they tend to boom.  These boxes produce aggressive sound which is just excellent for reggae, hard rock and rap music.  This is also one of the best subwoofer box design for deep bass.

Not all subwoofers perform well with bandpass boxes, however.  Whatever kind of box you have to house your subwoofer, be sure it is a matching enclosure.  You can check product information or consult customer care of your vendor to be sure your subwoofer will match with the design of your box.

So, now that you have a subwoofer, how do you go about getting the correct box for it?  You can buy your subwoofer box premade, which is the easier option for most people.  However, you may be a talented craftsman who loves making things and understands plenty of technical terms.

You can make your own box so that you can particularly design it to produce the deep bass that you want. Here are tips to consider when making a subwoofer box.

Tips for Making the Best Subwoofer Boxes to Get Loud Deep Bass

1. Consider the materials you intend to use for construction of your subwoofer box. You must use the correct materials recommended.  If you are on a budget and decide to use much cheaper materials, you will end up with an enclosure that is nowhere near the best subwoofer box design for deep bass.  Choose materials that are only the best quality. Best quality materials does not necessarily mean expensive.
2. Do not build a one box for all your woofers. Do remember that different boxes enhance sound quality from different subwoofers.  This means that the box type will need to be different for each subwoofer type.  The subwoofers may also be different sizes.  Boxes must be a nice fit, and not too large or too small if sound performance of each music system is to be optimal.
3. To determine the right size of box for your subwoofer refer to the manufacturer’s specifications. Also check out online for speaker box volume calculator.  There is also help for speaker box volume calculator.  Ensure that you use the manufacturer’s specs and online volume calculator.  This will help you know the best subwoofer box design for deep bass.
4. Make a sturdy box. A subwoofer box is all the time subjected to low frequency vibrations.  This means it must be sturdy or it won’t stand up to this.  The recommended wood for building a sturdy subwoofer box is fiberboard of medium density.  The minimum medium density fiberboard (MDG) that you can use should be ¾”.  MDG is costlier than plywood and particleboard but it is worth it.  It is denser, harder and stiffer.  It won’t resonate because it is a dead wood.  It won’t have issues like screws being easily pulled out of it, or warping when exposed to water.  All these qualities of MDG make it the ideal wood for making your box.  Do not be tempted to use poorer quality similar wood like particleboard.
5. Ensure the box is well sealed. Use the correct sealants as using wrong glue distorts sound quality.  Air packets or creaks in the subwoofer box also results is distorted sound.  Use wood glue, stuff the box with polyfill, you can use silicon to seal the edges and wood sealant to seal inside the box.  Any wood is to some degree porous and that is why some craftsmen like to seal it inside with some sealant.  Warning:  Silicon fumes will damage the subwoofers, so if you do use it, allow to dry overnight before mounting the speakers.
6. Air that arises out of subwoofer vibrations will need to be efficiently channeled out. This is what the ports are for. They are usually made of PVC.  Be sure to carefully calculate size for maximum efficiency.
7. Be sure to brace the box. When a speaker box vibrates wildly it may end up flexing.  It gets distorted.  To eliminate this distortion, you will need to add a brace or two inside the box.  Make sure to take into account the volume of the wood used for bracing so as not to eat into what should be the volume of the box.

DD Box Design

Vehicle interiors have limited space.  For subwoofer boxes, the size of the box matters and determines the quality of the sound produced.  So, in the limited space of a vehicle interior, could there be a best subwoofer box design for deep bass?

The DD box design takes a different approach from usual to get the most performance from non-optimum applications.    The creators of the DD Box started their research by testing how to make the most bass energy from a limited amount of space.

A type of high efficiency ported box was engineered, followed by a speaker that could be able to optimize the box energy.  By utilizing functions in the vehicle, a system was designed that could play low and loud and do it in a relatively small box.  The small box is the DD box.

The DD Box is ported.  It has a DD port which improves efficiency of the system and broadens the power response curve.

You can design a subwoofer system for your vehicle using the DD system.  You can exactly determine the sound quality produced in your vehicle by following the size/ports charts available with this system.  As you attempt to determine the sound quality in your car, bear in mind that the airspace is what makes the bass.

There are also DD woofers that are especially constructed for this system.  The woofers and boxes were developed together to produce the highest efficiency for a given box volume.

As you go about designing a subwoofer system for your vehicle, let the box shape and size determine the subwoofer size and quantity.  Do not have any predetermined ideas of size and shape.  The DD box system will help take the guesswork out of determining the best subwoofer box design for deep bass for your vehicle.
