The thickness of the wood used to build the box. Another type of brace, called a cross brace, should be used in any span that is 12" (30cm) or more to prevent panel vibration. and deduct this amount from the cabinet's total volume. 12" driver displacement = 0.0538 cu. The DD Box is more than just a style of box; it’s a scalable system that every DD subwoofer is designed to work with. Driver Displacement: The driver also takes up air space inside the enclosure. The subwoofer box design acts as a filter, cutting off … However, it is important to note that the basic calculations have some factors averaged or removed for simplicity, and the answers they give are only approximate. Enclosures should be built with very dense and heavy wood. These genres of music usually have a good amount of drums in the recording and do not have a lot of very deep bass information in the recordings. Ported subwoofer boxes do not have a linear frequency response. We're using 3/4" MDF again, so deduct 1.5" from each dimension. 1588.43 / 1728 = 0.92 cu. You will be contacted by Werksautosound to discuss the specifications and costs of your project before the build begins. It will be impractical to use round ports for these designs. Internal dimensions are what you'll want to go by when selecting a speaker for the enclosure. The purpose of an enclosure is to improve bass response and prevent woofer damage from over-excursion. Green - small sealed enclosure. External dimensions are what you have after measuring the space available in the vehicle. This type of enclosure is usually used when you are trying to reproduce music very accurately at a moderate volume. ft. Smaller ported boxes cannot be tuned as low as larger ported enclosures. We know that the recommended enclosure volume for a C-12 is 1.75 cu. ft. KICKER U app for iOS 3.57 / 2 drivers = 1.79 cu. For this example, we are building a sealed enclosure in a simple rectangular box. Fori 00% certainty that everything is correct, you may want to measure the box tuning frequency for vented enclosures. Also, since they don’t have an enclosure, there is nothing but the suspension of the woofer to control cone movement. The vent shape is not as critical as the total area of the vent. Ported boxes have another set of challenges. Cut-out Diameter: (13.9763 Inches) Subwoofer Mounting Depth: … All we do is multiply the dimensions together (1" x 1" x 20" = 20 cu. When you use ports, you there are a few things to remember.

This is a simple how to step by step of How To Make A Subwoofer Box For Beginners. 12x 3.14 = 3.14" Next, we'll multiply this by the port's length, 12". Since Hport is 3" you need to add 1.5"( 1/2 Of Hport) tO Lport. For deeper bass it will require more airspace, thus a larger box. Again, subtract only one thickness of wood from this height. Large ports sound better but take up more airspace and your enclosure’s total volume increases making the box larger overall. Ported enclosures are very popular because they can dramatically increase the output at specific lower frequencies. Whether it's a basic cubic box or a precisely designed kerfed / ported box, making sure your sub gets the appropriate enclousure for your needs can make a world of difference. They are sometimes called “acoustic suspension” enclosures. Should you find the need to build a more complex enclosure, do not be alarmed, just break down the enclosure into its … Infinite baffle mounting does limit the total output of the woofer and its power handling.

What type of speaker will you be using? Tools Required for Building Best Subwoofer Box Design for Deep Bass. We deducted two inches from the length so the braces would meet instead of overlap the other corner braces. Don't use "bathroom tile" type caulk, it won't do the job! Be sure to measure the tuning with the enclosure in the vehicle, the acoustic environment of the speaker can also affect its tuning. Next, you need to draw a box, on paper or in a program, it will take at least 20 minutes. To calculate internal volume, you must subtract the thickness of the wood. Total Cubic Inches / 1728 = Total Cubic Feet They do share a lot of the traits of both sealed and ported enclosures. The woofer is mounted inside of a two chamber enclosure in the divider between them. from the total volume. It can be as simple as a board or mounting surface (called a “baffle”). ft. per 10" driver. Red - infinite baffle enclosure They can reproduce low bass response that is very smooth and natural sounding. © document.write(new Date().getFullYear()), Stillwater Designs. High power levels below the tuning frequency will overdrive the cone movement and damage the speaker. Screws or staples should be placed approximately every 4" (10cm). The ability to accurately determine the enclosure volume is critical to building a quality subwoofer system. 14"-1.5" = 12.5" It will help a lot to visualize what you're doing. We can provide you with comprehensive Subwoofer Box Design Software for creating a high performance bass box. However, other factors will also influence an enclosure's total volume, like ports and bracing. Requires more woofers/enclosures/power for more output, Must be tuned to specific driver and enclosure volume, Can have “port noise” if built incorrectly. Now we'll look at braces. The area of a circle is the radius squared multiplied by "pi" or 3.14". That is why it is important to have an amplifier which has a subsonic filter to eliminate any damaging frequencies reaching the subwoofer. 52.5" x 7.5" x 15.5" = 6103.13 cu. An ideal infinite baffle mounting can be a challenge due to the potential difficulty of sealing off the front and rear of the baffle. The brace will contact the enclosure only on its ends where it should be glued and screwed or stapled. The other trait of ported enclosures is they have no control of the driver movement, called excursion, below the tuning frequency. There are a few things you will need to consider before making your final selection that will ultimately affect your choice in subwoofer enclosure style. Let's calculate driver displacement now to where we are. Port Displacement: Calculating the amount of space taken by a port will test your memory of high school Geometry! 1 mm = 0.0394 inches Venting rules: Take a good look at books written on the topic, as well — they'll give you an idea of whether you're up to the task. Subwoofers need to be given the proper amount of space within an enclosure to provide the best possible working environment. Let's say you're measuring a customer's vehicle for available space and it's basically unlimited in one direction. Quick view Compare Add to Cart. Calculate and subtract driver, brace and port (if ported) displacement from enclosure volume. A large ported enclosure can have substantially more output but at the cost of accurate sound quality. This means that below the tuning frequency of the enclosure, the driver will perform as if it was in an infinite baffle. This step by step shows the process to build a basic sealed box. This article details how to build a sealed speaker box, which separates the front and rear sound waves to improve the bass. Displacement refers to the space used by things inside an enclosure that influence total volume and is mostly associated with the drivers in an enclosure. First we'll find the total cubic inches on our two known figures, just multiply them together. Use of materials (printing, copying) is allowed with reference to the source. 1) The boards dimensions used for construction are as follows: 2 boards 22 1/4 inches by … Imagine how much time you will need to calculate the length of a port by its area and the net volume of a box, then calculate the occupied volume by the port, add it to the net internal volume of a box, and only after that, calculate the dimensions of a box, taking into account the material thickness. The smaller sealed enclosure will give you a little more output, or “bump” as it is called, before it rolls off but will start rolling off bass response at a higher frequency than a larger sealed enclosure. ft. / 2 = 0.46 cu. The following diagrams provide you with some help to insure your enclosure is built correctly. For a quick overview of the specifications that matter the most for subwoofer selection, we will begin with the ones that are the most broadly applicable. Add to cart. If you do so, the entrance to the port (inside the box) must be covered with hardware cloth, chicken wire, or expanded metal to prevent the polyfil from being blown out through the port. Most of the time the enclosures you will build will be standard shapes, like those shown below. This size box might work for a 12" driver or a 10" driver. The following information is available for you to use at your leisure. A perfectly centered cross brace can actually increase cabinet flex and resonance (at a higher, more audible frequency). © 2020 - Subwoofer Enclosure Design Software. This is a simple, three step process that can save you a lot of time and hair pulling! The subwoofer box itself acts as an amplifier, yielding to more bass than a sealed enclosure (3 to 4 dB). ft. per driver. Now it is a balancing act between size, sound, and power handling. How to build a subwoofer box to specifications? An isobaric enclosure is a unique type of enclosure where you use two woofers and couple them together to act as a single woofer with twice as much pushing power. This created distortion because it would not accurately reproduce the signal the speaker received. Ha ha. Changing either one will greatly affect sound quality, performance, and durability of the speaker. This means that some frequencies are louder than others and will not accurately reproduce the music as it was recorded. You will need to make sure that you seal the mounting baffle as good as possible to the vehicle so that the sound waves from the rear of the speaker cannot reach the front of the speaker to cause cancellation. ft. per driver. Any leaks or flexing will cause cancellation, resulting in reduced output. Check out CT Sounds Box Design blueprints! in. Too much power at lower frequencies can damage the speaker’s suspension components (surround, spider, tinsel leads, or voice coil former). Some of the woofers today require very little airspace to produce great sounding, deep bass eliminating the need to cut the box volume in half. We'll have twelve corner braces (one for each joint), and six cross braces (one for each wall). We recommend 3/4" (19mm) MDF although 1/2" (12.5mm) MDF is acceptable for woofers 8" and smaller. Quick view Compare Out of stock. They will also take up more space in the vehicle since they require more air volume. For example, small sealed boxes are often designed for the older rock, hard rock, or speed metal. What's the difference? That is why it is best to use a woofer specifically designed for this type of mounting configuration. It can be quite a long process to figure all these different things, but trust us, going through all the trouble is worth it when you get done and have an enclosure that sounds awesome! One of the key ways to control cone movement below tuning frequency is to use a subsonic, or infrasonic filter just like we recommend for infinite baffle. The rectangular port information given will yield the best results. It's very easy! An adjustable subsonic filter is necessary to maximize your output and protect your speaker. Good! Requires larger enclosure for deep bass response. The formula itself looks pretty simple: Area x Length = Volume. A straight vent is better than a vent that has to be bent or folded to fit into enclosure. A subwoofer box is very suitable for producing deep bass sounds in a car. Please use proper safety equipment and procedures when using power equipment. Your best bet is to use known enclosure design data such as given here, or to use a computer program such as LEAP 4.5 along with our published driver specifications to assist you in designing enclosures.

This is very rarely discussed but is very noticeable with large ported enclosures. We can't be held liable if a customer chooses a subwoofer larger than the specs provided for our sub box. So all bracing combined uses 250 cu. This will take up more space in the vehicle. When designing an enclosure, it is best to follow what we call "The Design Sequence." This produces a sound that many have described as “slow” or “mushy” bass. Countersinking makes it easy to fill over the screw heads for paint or carpet, and improves the appearance of the enclosure. This will allow for the best sound quality and longer life for the speaker. We can provide you with comprehensive Subwoofer Box Calculator for online creating a high performance subwoofer enclosure. The woofers can also be coupled with airspace between them in either a face to face, magnet to magnet, or face to magnet. For example, we'll say the customer wants to use our Competition 12" driver. Drywall screws work better if they are counter-sunk. Square and rectangular boxes are straight-edged boxes on all sides, whereas hatchback and truck style enclosures feature an angled front or back design that allows for installation in places short on depth such as single cab pickup trucks. Piece of cake! The box style or shape refers to the actual shape of the box. First and most important is the area and length are very critical for proper tuning. They can also be tuned to provide increased output in a narrow band of frequencies. Other concerns with bandpass types of enclosures is with sound quality. They are usually built within a range of internal volume specified from the manufacturer. When it comes to selecting an enclosure type to get the best sound from your woofer and matching it to your taste in music, it can be a little confusing.
