After unzipping and installation it gives two modules: for calculating subwoofer enclosures and for calculating passive crossovers.

UniBox (Unified Box Model)

Program for calculating acoustic systems of various types
Closed Box
bass reflex (Vented Box)
system with a passive radiator (Passive Radiator Box)
Bandpass Single Tuned Box
Very simple and logical program, runs in the shell Microsoft Windows Excel 2000. According to reviews, they function normally under Excel 97, if it is updated accordingly. Allows you to simulate sound pressure level, speaker impedance curve, frequency response and much more.
On the manufacturer's website you can find a database of many well-known speakers:
In addition, you can manually add speaker characteristics and create new databases

WinSpeakerz

Program for calculating subwoofers
WinSpeakerz - spelling as in the original - the work of a certain John Murphy, TrueAudio company.
The program is quite commercial, costs about $130, and a demo version is provided for free, without a database of speakers and other amenities (including a 150-page manual). The program is really good because, among other things, it has special function to take into account interior acoustics.

Crossover Elements Calculator

Calculation program
simplified Zobel circuit, L-Pad circuits for speakers, high-frequency sensitivity correction link, all required parameters inductors, built-in utility for routine summation of elements by the “resistor rule”, recommends the type of acoustics housing for the dynamic head.

Calculation of Coils for Speakers

Calculation program
Program for calculating the voice coil of a speaker. inductors. etc.
Knowing the inner and outer diameter of the coil, substituting the desired resistance, and the number of rows. You will receive coil winding data, and some reference data. The wire diameter is selected in the smaller side from the calculated ones, let it be better if there are more gaps than more rustling.

NCH Gen

Generator audio frequencies and special form signals
NCH Tone Generator is an easy-to-use program that generates (if there is presence sound card) sinusoidal signals (with a harmonic coefficient of about 0.01%)...,
...rectangular (with quite decent fronts)...
...sawtooth, etc. There is also a signal with a spectrum white noise, however, there are some complaints about him. Here is the noise signal produced by NCH T. Gen (in red) and the built-in SpectraLab generator (in blue). The second one is also not ideal, but better.

WinISD Pro Alpha

designed for calculating bass-reflex and closed-type acoustic systems
This program compares favorably with similar products in that it is easy to learn even with an English interface.
WinISD has its own extensive database of electrodynamic heads with all possible parameters. Till Resin parameters and geometric dimensions. It is also possible to replenish the speaker database with your own drivers using the editor. There is a simplified calculation of two-band passive filters of the first and second orders. And six various options active filters.
There is also a built-in audio frequency generator, which will be very useful when setting up speakers
Description of WinISD Pro Alpha in Russian

WinISD beta

for calculating bass-reflex and closed-type systems
I personally used the WinISD program as a backup calculation for the bass reflex of acoustic systems based on car speakers.
The program surprisingly accurately calculates the bass reflex, taking into account even virtual zoom volume of the box when filled with sound-absorbing material.

Power Port

Power Port type bass reflex calculation program (Polk Audio patent)
This program was invented by Matt Polk and George Kloepfer. The idea is to reduce the speed at the output of the bass reflex tunnel and at the same time reduce its length while maintaining the same setting.
The calculation program is designed as Excel file. To prevent this whole thing from opening in a browser, it is archived in ZIP.

VAS Calc

Program for calculating equivalent head volume.
The program is written in Microsoft Excel.
A program for calculating the equivalent volume of the head using the added mass method.

Harmon3way

Program for calculating interference distortions of the frequency response.
The program is written in Microsoft Excel. Everything is simple and clear.
Program for calculating interference distortions of the frequency response by G. Tatevyan

Blaubox

Program for calculating subwoofers
BLAUBOX is the creation of Blaupunkt, as is clear from names, - program completely and absolutely free. The somewhat simplified and rough graphics are fully compensated by the fact that the program works, firstly, quickly, secondly, it can calculate all three main types of subwoofers (closed box, bass reflex, bandpass subwoofer), thirdly, it is extremely easy to use, - fourth - can draw working drawings of the box based on the calculation results. Here are examples of the results produced: the frequency response of two simultaneously calculated subwoofers and a sketch of a box.

Perfect Box 4.5

Program for calculating subwoofers
Perfect Box 4.4 is a pre-sale version of the program, but it is almost completely equipped with functions and options. Outwardly it is a rough DOS thing. In fact, it is the best program, in my opinion, if you get the hang of it. Calculates closed boxes and bass reflexes.

Goes quite well as a dowry large base data on the speakers, which can be easily replenished by you as the need arises, and also a thing of little use, but fun - the EQ2.EXE program, with which you can calculate the active frequency response correction link. The program is tied to the basic parameters of the frequency and quality factor of the correction filter.

Box Plot 2

Program for calculating subwoofers
Boxplot 2 is a pre-sale version of the program, and therefore some of the functions do not work. The main advantage is that the program is very instructive, since right on the screen you can vary the parameters H = fb/fs (the ratio of the bass reflex tuning frequency to the resonant frequency of the head and ALPHA = Vas/Vb (the ratio of the equivalent volume of the head to the volume of the box, including a closed one). After five minutes of working with the program, a person who has never read anything on loudspeaker theory in his life already knows the most important dependencies. For practical calculations, the program is not very convenient due to its reduced functions, although with some skill it is possible to work. However, if anyone wants to pay 25. dollars - it says somewhere - where...

P.X.O.

Passive crossover calculation program
The PXO (Passive X-Overs) program, as befits its age, runs under DOS and works perfectly. You select the frequency (or frequencies, for a three-band system) of the section, the slope slope from 6 to 24 dB/oct and the filter type (Butterworth, Linkwitz-Riley, etc.), and in return you receive graphs of all the main characteristics and values of the elements included in the filter chain, the latter being schematically depicted in the lower window of the user interface.

Note:
When everything is done to your taste, the question naturally arises: “How to calculate inductance?” - they are not ready-made, unlike capacitors. For this purpose it serves even more simple program below - COILS.EXE

Coils (russ)

Everything is very simple here: enter the required inductance value (in millihenry), wire diameter and frame diameter. You get the required number of turns, the length of the frame, the wire consumption and its resistance, which you can compare with the resistance of the voice coil and make a command decision.

Coils

Inductance calculation program
If anyone has problems with the Cyrillic alphabet under DOS, use the English interface.

UniBox program for calculating acoustic systems with different types acoustic design:

Closed Box

There is a description of how to work with the program in Russian. We recommend.

JBL SpeakerShop

JBL SpeakerShop acoustics and subwoofer calculation program. JBL SpeakerShop consists of two independent and complementary parts: Enclosure Module - for calculating acoustic design and Crossover Module - for calculating the parameters of crossover filters. In addition, there is a database of speakers various manufacturers. We recommend.

BassBox 6 Pro

One of the best programs of its kind for calculating acoustic systems of all types: closed box, bass reflex, bandpass, as well as for measuring the parameters of dynamic heads. Huge base data parameters of the speakers, almost all, famous manufacturers. We recommend.

Very useful program For graphic display(drawing) diagrams and printed circuit boards. At your disposal: user-friendly interface and more than 1300 standard elements— you don’t have to “draw” each microcircuit or resistor. Nice program :-). We recommend.

PSU Designer

A very useful program. With its help, any power sources can be easily calculated - bridge, single- and full-wave, kenotrons and diodes, with L and C filters. The database already contains the necessary data for the most popular rectifiers; all you have to do is set the voltage at secondary winding network transformer and load current (resistance). The program simulates the shape of voltage and current at any point in the circuit and warns if any extreme permissible value for the rectifier is exceeded. A new version PSU Designer allows you to save files and edit them (information from the AV Salon website)

JBL Speakershop includes two independent programs: Enclosure Module and Crossover Module.

The Enclosure Module is designed to determine the required volume and dimensions of low-frequency loudspeaker enclosures. The sound quality of the design is assessed in normal listening level mode (small signal analysis, including group delay, phase and amplitude-frequency characteristics, voice coil resistance) and at maximum volume(large-signal analysis taking into account the thermal acoustic power index at mid-frequencies and the maximum power at various excursions).

The program module under consideration offers modeling of enclosures with a bass reflex, custom, optimal and designed for a unique frequency band, enclosures with a passive radiator, as well as closed systems optimal or custom type. Simultaneous demonstration of all types of designs facilitates them comparative analysis.

The program describes the structure and main parameters of each type of housing, and contains lists of their advantages and disadvantages. For beginners, there is a help file to make the job easier, and examples are included with relevant notes and instructions.

The set of minimum parameters required to design the case includes the name of the manufacturer and model number, as well as the value resonant frequency dynamics, air volume with elasticity equal to the elasticity of the speaker suspension and the quality factor of the device, taking into account all losses. The full list of parameters includes a long series of mechanical, electrical and combined values of the designed device. Among other things, the JBL Speakershop Enclosure Module plots maximum sound power, amplitude-frequency response (normalized and when a test signal of 2.83 V is applied), voice coil resistance, group and phase delays.

The second part of the JBL Speakershop program – Crossover Module – is designed to determine the parameters of crossover filters that separate the signal into low and high frequencies. The utility calculates two- and three-way passive separation systems of the first, second, third and fourth orders using a number of standard filters: Chebyshev, Bessel, Butterworth, Gauss, Legendre, Linkwitz-Riley and some others. The result of the work is the construction of a detailed electrical schematic diagram a unique crossover system with a detailed description of each element.

In Russia JBL program Speakershop has become widespread among radio amateurs who are developing their own car speaker systems. However, the amplitude-frequency characteristics of the sound-reproducing device calculated and plotted in this utility automotive system very inaccurate and highly dependent on the design features of a particular machine. For proper operation Additional data must be entered into the program, for example the transfer function of the car interior.

The JBL Speakershop program was created in 1995 by specialists from the American company JBL. The company is part of the Harman International Industries association, specializing in the production of acoustic systems high class and related electronics. JBL products became the basis for the development of the THX standard, and the company's dynamic heads are used in cars from the world's leading manufacturers.

The JBL Speakershop interface language is English only. However, on the Internet there is detailed description works in Russian.

System requirements for the utility are minimal. JBL Speakershop operates in operating system Microsoft Windows, including latest versions: Vista and 7. The only exception is the lack of support for 64-bit operating systems.
