The frequency range—particularly the low frequency extension, will guide some basic dimensions related to the speaker cabinet design. Do you want a floorstanding tower speaker, or a pair of bookshelves? Are you designing a full-range speaker or a subwoofer? Those are highly advanced designs that incur their own set of difficulties and design challenges.

Example : I want to go with a tower design that is ported. Where will that port exist front or back? Each of these considerations needs to take place before proceeding too far down the path of loudspeaker design. For now, just know that you have some preliminary decisions to make before going too far.

Some, however, may opt to roll their own passive crossover network—perhaps based on a computer recommendation or an existing kit design. It all depends on how far you want to take or customize your loudspeaker design. While you can certainly design a box, do your own math, and add your own drivers, investing in a good piece of speaker design software will do wonders.

AJ Designer — AJ Designer speaker design software has the ability to help with bandpass, vented, and sealed subwoofer designs. Unibox — Unibox is more of a sophisticated spreadsheet than a piece of software.

And all of that pounding, feel-it-in-your-chest, rumbly and explosive bass you love at concerts and in theaters is actually up around hz. So, then, why bother with a huge, huge speaker box tuned down to 17hz? You might just have to experience it. After building this thing and playing with it and a tone generator, I can tell you that most of the components of my house certainly resonate somewhere in that range.

For my money tough, the real feel-it-in-your-chest frequency is in the low 30s. I think my lungs must resonate at about 31hz. Ok, onward. It turns out that very loud infrasonic sound is not something humans normally experience very often, and when we do, it connects in some crazy visceral ways. Very high amplitude infrasound is produced naturally by things like earthquakes and very powerful storms like tornadoes and hurricanes.

They mostly just register as strange sense of dread or as an oppressive weight in the air, like an enormous power or sense of foreboding. Hollywood has largely ignored infrasonics because it takes very large, very powerful audio equipment to produce them. Further, for a few reasons related to the way they work, most sound systems out there would burn themselves up without making a sound if you tried to play an infrasonic recording for very long.

Recently though, with the protections and efficiency provided by digital amplifiers, movies have started including infrasonic effects, and they are a pretty imposing experience. It turns out there are some very clever approaches to subwoofer design that can provide pretty impressive borderline infrasonic sound without spending a fortune on drivers and amps.

However, it turns out they are not all that complicated to build yourself. The one I finally went for is called a folded tapped horn.

Put simply, a horn maximizes the efficiency of the transfer of kinetic energy from an oscillator like a speaker to the air around it the room. When an oscillator like a speaker or a tuba players lips is used out in the open, it wastes the majority of its energy thrashing the air immediately surrounding it in to turbulence, not cohesive sound waves. In order to work properly, the size of the horn must be tuned to the frequencies for which it is intended. The lower the frequency, the larger the horn.

Higher frequencies work with horns only a few inches long, which is why they are often used on the tweeters in high end loudspeakers. On the other hand, a horn tuned for a subwoofer at 17hz for example, needs to be something like 25 feet long.

Folding Horns. The first big feature of this design depends on the fact that the horn does not have to be straight to work, it can be folded up like a tuba and still work very well.

Also, the tube that comprises the horn does not have to have to be round.Designing and building your own subwoofer for your audio system can be a great way of improving its sound. Building your own subwoofer is really not that difficult especially if you get a relative or friend to do the woodworking for you! Why should you build a subwoofer? Well, frankly most loudspeakers, particularly the smaller ones, are simply not capable of reproducing the lower bass frequencies no matter what the specifications claim.

If the loudspeakers are relieved from trying to play the lower bass frequencies, they will sound better at higher volume levels. Finally, a subwoofer can be located anywhere in your listening area, which provides you with much more flexibility in positioning your main loudspeakers for good sound. Several types of subwoofers systems are covered in this site, including sealedportedbandpasspassive radiator and transmission line systems. Also included is information that will help you to choose the system that would best suit your needs, design and build a subwoofer that meets your needs, and techniques to use to get the most out of your build.

Several projects are also covered on this site, just in case you are looking for some ideas. Also covered in this site is the designing of subwoofers for car audio use.

Not interested in building your own subwoofer? Well, the information on this site can still help.

Australian beeswax is used on the outside of the horn cabinet and heavy cedar oil was applied to the mouth of the horn.

Mark reports that the horn speakers can draw an extremely accurate soundstage, sound excellent and have lead to a whole new listening experience with Paris, a 2. This open baffle speaker project is simple to build and uses low cost speaker components. The project was inspired by the "Big Air" open baffle system by Jim Strasser. Bruce indicates that the speakers have an excellent overall sound but cautions that open baffle speakers systems are "bi-polar" and not for everyone.

The enclosure is a 6. The loudspeakers use a single Fostex FEEn fullrange driver with no crossover circuit. The speakers work well as nearfield monitors and combined with a subwoofer the speakers can be used for home theater duties. The speaker box plans are from the datasheet that was supplied with the drivers.

The loudspeakers use a single Fostex FEEn fullrange driver and no crossover. The two chamber box design extracts good bottom end from these low displacement drivers. The speakers will be used in a home theater so for a non-reflective finish the speaker enclosures are painted with a undercoating paint for a stipple like finish and flat black paint.

Mark reports that the speakers are an excellent mate for use with his 2.

Plan #1 - Sealed Subwoofer Enclosure

The 2-Way crossover uses a 3rd order Butterworth filter at 4 kHz with an impedance correction circuit. The nominal impedance of the speakers is noted at 4 ohms and the frequency range is about 60 Hz to 20 kHz. The enclosure is made of MDF and solid oak and each tower weighs about 60 lbs. Adam reports that the Ion speaker build is his favorite so far - "The Audax HMCO woofers produce very warm natural tones up through the upper midrange.

With the TangBand SC tweeter the highs are crystal clear, detailed but far from harsh. The speaker enclosure uses a pair of ready made curved Dayton Audio 0. The crossover used is from the Swans M1 but Daniel used hound wound inductors. Speaker Projects Gallery - Parts-Express.

Each speaker project includes complete drawings to illustrate construction of the speaker enclosure, crossover schematics, a full parts list and photographs of the finished speaker project. For those who are not great with woodworking, the TriTrix is available as complete kit. The DIY speaker kit comes complete with all the parts and tools required except for a soldering iron to build a great looking, little rear loaded single driver horn speaker system.

The small horn speaker kit goes together much like ready-to-assemble furniture. The end result is an attractive and compact horn speaker that sounds great and is fun to build. The speaker enclosure for this project is constructed using 20 mm thick black granite!

These wonderful looking bookshelf sized speakers were put together by Radoslav in Slovakia. The loudspeaker enclosure is a vented 15L design that is tuned to 45 Hz through the rear firing port.We can provide you with comprehensive Subwoofer Box Calculator for online creating a high performance subwoofer enclosure. Build a ported box, sealed box for your low-frequency speaker. Make a subwoofer enclosure plan. Calculate a speaker box volume, port length and other parameters without getting confused in formulas.

Everyone understands that the box is an indispensable part for the proper operation of the low-frequency speaker, which is designed to work in a certain volume, without it, the subwoofer speaker will simply chase the air, while the efficiency will decrease several tens of times.

Without a box, due to the lack of the necessary damper, the speaker is very easy to pull out of the stroke, this is when the coil starts to come out of the magnetic gap, it is at this point that any slight distortion of the diffuser can lead to a coil's impact on the core cylindrical magnetic core in the center of the coilwhich leads to the detachment of the winding from the coil frame.

Of course there are exceptions, for example, as Free Air subwoofers, which are designed to work in an open volume, but the efficiency of these subwoofers is very small, it is recommended to install them only as a last resort.

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. Next, you need to draw a box, on paper or in a program, it will take at least 20 minutes.

Other critical factors include the internal net box volume and the stiffness of the enclosure. If the box is made smaller than recommended there will be a reduction in low frequency extension and output. If it is made larger there may be a risk of bottoming the driver.

In alternative designs, it is recommended that the box should have an equivalent stiffness by using solid materials and bracing. If a vented box is used, careful attention should be paid to the design of the vent.
