Best Subwoofer Box Design for Deep Bass
Best subwoofer box design for deep bass
Music is known as nature’s remedy for any kind of illness or ailment. People who are passionate about music know the importance of each beat and each tune in creating an impact on the soul of the listener. The smallest changes in the pitch or bass of music or song can go a long way in creating a more ambient environment for the listener.
Just for this purpose, there are tonnes of equalizers and customizable speakers available which allows us to make desired changes to our favorite music and make it more satisfying to our senses. The most commonly used device for this purpose is the ‘Subwoofer Box’.
A ‘Subwoofer Box’ is basically a loudspeaker designed specially to produce low pitched frequencies which cannot be normally produced by a simple speaker. The main purpose of these speakers is to increase the intensity of the bass of the sound produced.
A subwoofer is not an independent device and is more of an accessory to a normal loudspeaker. It is an attachment mounted on a normal speaker to augment the low-frequency sounds produced by the speaker so that it is effectively transported through the high frequency range.
They generally work for sound frequencies in the range of 20 to 200 Hz. Some THX approved systems are capable of working below 80Hz.
Why you should build your own subwoofer box?
So now that we know what is a subwoofer box there arises the question of why should you go to the pains for making your own subwoofer box?
Well, for starters a normal loudspeaker is basically incapable of producing the low frequency sounds while playing any music, no matter how costly it is or whatever is mentioned in the specifications. Also, the speakers face interference in the high frequency audio due to its incapability to perfectly play the low frequency sounds involved.
A subwoofer box eliminates this problem and especially increases the bass of the music. Now that the normal speaker is free from playing the low frequency sounds they can perfectly produce the high frequency sound at the finest efficiency.
Additionally, if you own a car or any other spacious vehicle, then it goes without saying that it comes equipped with a music system. To enhance the sound output quality of these speakers, subwoofer boxes can be used to augment the low frequency audio and also boost the bass.
A subwoofer box is very suitable for producing deep bass sounds in a car. Especially a 10-inch subwoofer can be placed comfortably in the compartment of a normal car and can be used for listening to high quality music.
How to build a subwoofer box to specifications?
Subwoofer box is very popular among not only among music enthusiasts, but also among the casual listeners as it enhances the quality of the audio and makes for a more long-lasting after effect.
And contrary to popular belief, it is very easy to make one yourself with cheap materials you can avail and those are capable of producing sounds of quality which is at par with that produced by some of the most expensive and premium subwoofers.
But in reality, the main attraction of making your own subwoofer is the creative freedom you are getting to design a unique device reflecting your style.
What are the components required to make your own subwoofer box?
There are not many complicated tools required for making your own subwoofer box apart from the basic necessities like the compartment building tools and the audio driver. The driver is the most crucial equipment and greatly affects the sound produced by the speakers.
Another major concern is the volume of the box we are building. The shape and volume of the box play an important role in determining the quality of the sound produced and hence after finalizing the dimensions of the box we can go creative and design it to our desired shape.
The complete list of pieces of equipment needed other than the audio driver is given below:
- Speaker terminals to produce the sound.
- An electronic amplifier to power the subwoofer box.
- A damping material for the insides of the box. It improves the acoustics. Foam can be a little expensive, so any other materials like pillows can also be used for the purpose. Fiberglass is often used for providing insulation.
- For making a ported subwoofer one will need the materials for making a port. Drainage pipes can be effectively used to serve the purpose.
- Materials to design the container or the box or the cylinder are required. Boxes are generally designed with paints and varnishes whereas cylinders are designed with foams and fabrics.
Other than the pieces of equipment mentioned above you are going to need some more working tools which are listed below.
- Electric drill
- Industrial or Carpenter’s glue, if working with wood
- 2 inch screws
- A jigsaw cutter
- Circular saw
- Terminal cup
- Silicon caulk
Determining the budget for the Subwoofer box
It is very important for any project, especially when you are building one yourself to determine the budget because if you are going to spend exorbitant amounts then it is really not a good idea to go to the pains of building yourself a box instead of just buying one from the market.
The budget can also differ depending on the quality of the project you are making so it is very necessary to keep an eye on the money while completing the project.
The basic materials for making a subwoofer box are not that costly and can be purchased well within 30-40$. The main cost is spent on the enclosure. You can also purchase a suitable enclosure online to reduce the cost of making.
The basic architecture of making a subwoofer box is very simple and the time that is taken to build one solely depends on your productivity and experience in working with the necessary pieces of equipment.
If you are experienced with woodworking tools, then you can build the basic architecture and fit the components well within one to one and a half hours. Even if you are not very much expert at working with these pieces of equipment, then also the whole project does not take more than 4 to 5 hours.
What is the Difference Between a Ported and Sealed Sub Box?
A sealed subwoofer box is a basic design and like the name itself, it is essentially a completely sealed box with no outlet. These types of boxes often suffer damping due to the sealed air inside and as a result the power needed to be supplied is increased to overcome the damping effect.
On the other hand, a ported subwoofer box is simply a subwoofer box created with a port in it just for the passage of air and thereby eliminate the damping effect. It also reduces the amount of power required to be given to the subwoofer.
What’s Better a Ported or Sealed Subwoofer Box?
There are pros and cons to both the designs and it depends entirely on the user to decide which design to use. For a sealed box design the effective size of the speaker can be made smaller and requires lower space. For a ported box design, the amount of power required is low and there is no damping effect.
Subwoofer Enclosure Design Plans
The next important step for making a subwoofer box is finalizing the design of the container whether it is a box or a cylinder. This can be a daunting task for anyone but there are various free software and programs available for this purpose.
Most popular programs for this purpose are Sonosub for cylindrical design and WinISD for making a box design. You can put in the desired requirements and parameters in the program and they will show the most optimum design for the subwoofer box you are making.
After all these aspects are taken care of, the real procedure for making the box or cylinder is a simple technique and employs common woodworking knowledge to assemble. You can also use cardboard as the base material, but wood is preferred due to its better insulation and acoustics.
Once we have finalized the design and dimensions of the final box, we have to build the required structure using our base material and then just fit in the terminals and driver. We have to make the necessary terminals if building a ported system.
Determining the Dimensions
The Least Depth of the Box
The least depth of the subwoofer box refers to the front to back measurement of the depth of the box. We have to add 2 extra inches to the obtained measurement as the main subwoofer device will be mounted at the front.
So necessary assumptions are needed to be made for making the outlet of the speaker and fitting the subwoofer. This measurement is referred to as the least depth of the subwoofer.
Minimum Height and Width of the Box
After determining the depth of the box the next important measurement is to determine the minimum height and width of the subwoofer box. These measurements are important for determining the mounting dimensions of the subwoofer and are necessary for knowing the correct value of the space which the box will occupy.
Once all the measurements of the height and width of the subwoofer box are complete, it can be calculated if the subwoofer box can be fitted correctly into the available space.
The frame should have enough space to eliminate any kind of damping effect produced due to the closed air space. Necessary changes have to be made for fitting the box in the available space.
The Internal Dimensions and Volume of the Box
All the above-mentioned measurements are for determining the external dimensions of the subwoofer box, but the performance of the box cannot be determined unless the internal dimensions of the box are obtained.
The determination of the internal dimensions is not that difficult and just requires the elimination of the width or thickness of the box material from the external measurements to reveal the internal measurements. These values are necessary for determining the volume of the box that affects the resonant frequency of the cavity inside.
The internal volume obtained from the calculations is converted into cubic feet from inches for the ease of checking its compatibility with the manufacturer’s specification provided along with the speaker and the driver. The volume needs to be adjusted for producing the perfect deep bass.
The speakers are provided with a manufacturer guide that consists of all the important measurements required for producing deep bass. So while building the subwoofer box the dimensions should be matched with the specifications for obtaining the most efficient output.
After all the internal dimensions are finalized, we need to add the ½ inch which we have kept aside while determining the internal dimensions. This ½ inch is important for obtaining the final external dimensions before moving into the final construction process.
Finalizing of the external dimensions is very vital because if we start working with wrong measurements then the final product will be erroneous and it will end up taking more space than intended.
Not only about the space, but the wrong measurements will also affect the performance of the subwoofer as accurate dimensions are necessary for determining the nature of bass produced by the box.
How to Determine Port Size for a Subwoofer Box?
A port as discussed above is simply an outlet for the free passage of air for entering and leaving the subwoofer container. It decreases the damping due to sealed air and improves the depth of the sound.
A port can generally be of any size and shape but since most commonly pipes are used for making ports round shape is the most commonly used port in subwoofer boxes.
Just like for determining the subwoofer container design there are numerous free online tools available for calculating the required port size and shape. This software needs to be fed the required details and they will produce the most optimum results.
You need to collect the following data for determining the port dimensions through an online tool:
- The number of drivers being used
- The size of the driver
- The volume of the container
- The tuning frequency
- The Xmax
The software provides us with all the necessary information like the size of the port along with the maximum and minimum range of variations allowed and most importantly the length of the vent used. PVC pipes and drainage pipes are most commonly used for the purpose of making a port.
The correct determination of a port size is necessary because a port of the correct size will make the air inside the container resonate with the sound being produced by the speaker and as a result, the bass output will be more enhanced.
How to Tune a Subwoofer box?
The tuning of any audio device is necessary for obtaining the optimum output and improving its performance. Subwoofer boxes are made for the purpose of producing low-frequency sounds, so the effective tuning is necessary for eliminating any kind of damping effect or interference.
The tuning of a subwoofer depends on many aspects but first of all the driver needs to be determined which is going to be used in the subwoofer. The specifications of the driver influence the tuning required along with the dimensions and the volume of the container.
Listed below are the steps involved in effectively tuning a subwoofer box (ported).
The following steps are applicable when working with round ports.
- You will require a multimeter which has been set to measure current. When the multimeter is connected in series between the subwoofer and the amplifier, the impedance will drop to the lowest value since it is a ported system, the opposite would have happened for a sealed system.
- At the resonant frequency, the meter will give the highest reading possible. If the resonant frequency obtained is not at par with our specifications or calculations, then the port length needs to be adjusted for getting the optimum value.
- Get the following details for tuning the subwoofer box-
- The desired frequency of the output
- The inside radius of the port vent
- The length of the vent
- The internal volume of the enclosure
The parameters mentioned above are used for determining the resonant frequency of a ported subwoofer system. This might look like a complex mathematical equation, but almost all the major components like speakers, drivers, and amplifiers come with all these values pre-specified by the manufacturer.
For homemade subwoofer boxes, fixing the port frequency is the easiest way to tune your subwoofer. If the amplifier comes with a frequency control option, then it can be used to set the gain and filter to the required level for obtaining the resonant frequency.
Subwoofer Box Design for 10 inch Speakers
A 10-inch subwoofer box is ideal for a family car and usually fits in the bonnet space of the car. It is normally suitable for any kind of car, but if you own a car of very compact design, then you should measure the compartment space before making this decision.
Instead of making it manually, there are many enclosures for different sizes of speakers available online. Also, if you want to make it yourself, then you can use any of the online tools available for determining the enclosure dimensions which will suit best your speaker.

Width= 40 inches
Depth 1= 19-1/2 inches
Volume (internal) = 3.00 cubic feet
Now we have covered all the necessary information you need to know about building your subwoofer box. All the discussed topics are concerned with the construction of the subwoofer box, but the designing or customization of the subwoofer is purely limited by your imagination.
Many people use paints and varnishes for designing while many others can use linings of different fabric materials for customizing the look and design of the subwoofer box. While building and designing your own subwoofer box it is important not to have any kind of preconceived notions about the shape and size of the box.
You need to develop a basic diagram of the subwoofer box you want to make and then calculate the dimensions of the same. After we have obtained the required dimensions we have to determine if it will be compatible with the space we have available.
Once we have the final dimensions, then we have to decide the power and capacity of the subwoofer according to the measurements available to us. This is very important as the amount of available air space determines the quality of the bass produced by the subwoofer.
So, now that you know everything about making a subwoofer box, what are you waiting for? Just get out there and prepare to build your own bass monster.
