THE BOX BUILDER is an independent software engineering company which specialises in developing Internet software solutions for the management of complex information networks, and which offers its services as an online application service provider (ASP). An overview of WinISD, the free Windows based software for designing speakers and subwoofers. Boxnotes - check your enclosure design for resonances, factor in the volume taken up by ports and print your cutting list Sonosub - design a cylindrical subwoofer.
SPL changing with different values for Q The second step is to set the correct System input power. WinISD takes whatever you set as the System Input Power and then adds the boost. The result of this process must not exceed the maximum power of your system. This means that the System Input Power must be set lower than the maximum power by an amount equal to the boost. The following table shows how much to reduce the power for a given boost Boost in dB Divide maximum power by: 1 1.3 2 1.6 3 2.0 4 2.5 5 3.1 6 4.0 7 5.0 8 6.3 9 7.9 10 10.0 As an example, the is designed for 240w maximum power and has a boost of 6dB.
For 6dB, we must divide the maximum power by 4, so we set the System Input Power to 60w. Boosted vs Unboosted Signal Generator A signal generator is also included for testing speakers via your sound card and has a range of control options including selecting the frequency from the cursor position on the response graph. If using this function, be careful not to overdrive the output The generator allows you to produce a single frequency, or a sweep across a range.

For the single frequency option, you can manualy specify the frequency, or you can use the cursor to pick the frequency from on of the WinISD graphs. Unlike some other products, this one doesn't produce any clicks during sweep mode. There is also an output attenuator, allowing control of the signal level. Not Clipping Setting the Attenuation control to 6 was enough to restore a pristine sine wave. Your results may vary Now, whenever I use the tone generator, I use TrueRTA to make sure I'm not getting a clipped signal Flanged vs flared ports Some people get confused as to the difference between flanged ports and flared ports. A flanged end is an end that terminates in a flat panel, such as the wall of an enclosure.
A flared end is one that has an expansion section, typically one quarter of a circle in cross-section, to control port noise. WinISD can factor in flanged ends by applying an end-correction factor.
The current version cannot handle flared ends. Here are some examples. Quick Tip: Entering driver parameters Driver parameters can be a pain to enter into the database. If you're having trouble getting it to accept parameters, follow this advice from one of the authors. Try entering just Qms, Re, Mms, Cms, Bl, Sd, hg, hc, Xlim (optional) and Pe. Do not change any parameters the program calculates. That way the data is consistent.
You can of course add the dimensional parameters if you like If you can't get that to work, user Soho54 from AVSforum swears by the following. Enter the numbers in this order: Sd, Re, Le, Fs, Qes, Vas, Qms, xmax, and then Pe.
That's it, now save Case Study used to prototype the illustrates the use of WinISD Additional WinISD resources. Steve Dart's excellent including entering driver parameters without errors. A few observations about the various graphs can be found in this. There are quite a few subwoofer driver files at While you're here, you might want to check out some free software that compliments WinISD Whilst WinISD is excellent for designing your working volume, tuning frequency and filter frequencies, there are some things it doesn't do. The following sofware adds plenty of value to your design process. check your enclosure design for resonances, factor in the volume taken up by ports and print your cutting list - design a cylindrical subwoofer. Check resonances and clearances, - find the correct port diameter and flare size to avoid audible turbulence - calculator for finding component values for a 2nd-order high-pass filter - Software for designing advanced QRD diffusers You can download WinISD from in Finland.
This overview describes version 0.50a7 Pro There is a later version which has similar functionality ie it also calculates box volumes for ported and sealed enclosures using an easy to use interface and also calculates port lengths. Many graphs are available, including the three used in the section, ie Sound Pressure Level, Vent Air Velocity and Cone excursion, all relative to frequency. An extensive database of drivers is included and it is easy to add your own entries. This lets you compare different drivers before you go out and spend any money. It is surprising how the final box size and response varies with the driver chosen.
Bigger and dearer isn't always the best. Choose wisely, grasshopper!
Details Rating: 4.3/5 Price: Free Box notes is an excellent speaker design software both for DIY enthusiasts as well as for professionals. It is the best loudspeaker design software available in the market and one that will guarantee top performance. It is well detailed as well as simple to use making it quite ideal for all users. Other Platforms As it is the case with the majority of the applications that require being installed into computer systems including those that are portable, the platform is key.
This is critical in filtering the applications that can work for your case as well as those that don’t go to establish. Speaker Designer for Android. Details Rating: 4.7/5 Price: Free Trial Available FINEBox is the leading speaker design software. With this application, it designing of headphones, micro loudspeakers, PA systems, and Hi-Fi systems is greatly simplified and results much more effective.
The software also offers rich features such as 3D display of the various elements as well as a simulator for different designs. What is Speaker Design Software? A speaker design software is a computer application that is developed to assist the designers of speakers in bringing out the best designs that will have various effects. Essentially, the software in this category will pick all the components of the speaker being developed in terms of measurements as well as the type of materials being used. You can also see From these, the software is able to simulate the sound quality that the speakers being designed will be in a position to produce.
As a result, it is possible to expect the very best in terms of performance as well as optimization. You can also see Computer aided designs as well as simulation are areas that have led to the development of products that could have otherwise been very challenging to have.
There is no exception in the field of speaker designs as it can be noted that there are quite a good number of these applications.
