Unibox and T/S Parameters

Set Le2 and Re2 to zero.  DCR is the same thing as Re.

That's what I do...I've never needed those values. 

Here's a tip on using Unibox with a less-than-complete set of given parameters:  You know that the values in blue are changeable, and the values in red are calculated by the program.  The top left set of boxes under "Drive Unit Parameters" allows you to fill in several T/S parameters.  Sometimes you'll find one of those missing in the supplied data;  often it's Sd.  You can look at the changes the program makes to the parameters in red in the middle column, namely Bl, Mms and Cms, according to what you input into the left side.  So if Sd is missing from your data sheet, you can try some different numbers in that block until the numbers in red correspond closely to other supplied data.

In other words, watch the middle column values that the program calculates to see if anything appears far off from the given data.  If something is off, there will be a correction you can make in the inputs to get it right.

And this:  there's a box over in the right column that says "Drive Unit Configuration".  Make sure that is set to "Single drive unit" as you input supplied parameters (although it should come up that way by default).  If you are working up a multi-woofer box, change that Drive Unit Configuration box to reflect what you have only after all the parameters for one woofer have been inputted.

After you've started a project, use the 'Save' function under "Design Database" to keep your woofer on file.

You'll probably have to change a security setting in your security software.  As I understand it, macros in general are sometimes used maliciously.  I must have my settings alright in Zone Alarm because I click on "enable macros" and everything is okay.  (...but don't ask me what a macro is!)

Speaker Workshop has a Help file that would make a small book.  If you read it completely you should get onto the right track, and then it's all about working with a setup and experimenting with results. It does take time.  Here's a few things to get a project started:

The top drop-down toolbar is where you start, add something, anything.  You'll eventually see those tools in the toolbar change to different things depending on what you have working at the moment.  But to start, choose 'Resource', then 'New'...then choose 'Network'.  You will name your project here.  Everything you add will be installed in this network.  Using the same tool, choose 'Driver'.  Input the drivers and their parameters that you want to work with.  This is where you also import .frd and .zma files (freq response and impedance) into your network.  I use SPL Trace to make these files from manufacturer's published graphs like these.

You'll get a screen opened with nothing but a symbol that reads "Source".  One side is positive and the other is negative, and it represents the power supply.  Everything in the network is built onto that source.  Insert the drivers into the network by choosing 'Network', 'Insert', and pick the drivers you have entered into the database.  With supplied power and drivers, it's now a matter of designing the crossover.  You can experiment and get familiar with how it all operates by right-clicking on the open window and choosing 'Insert' and then choosing some stock crossovers and impedance compensation circuits...just to see how the program links things together to form a schematic.  Also, right click and choose 'Properties'...check the blocks under the 'General' tab.  Name this project, and go back up to the toolbar and choose 'Network', 'Calculate response'.  If you have all the blocks checked, some files will appear in the left column.  These will show the freq response and impedance of your project.  The 'auto-overview chart' is a third one that shows up, and you'll find that the chart is a valuable working tool.  With the chart function, you can combine several individual crossed-over driver responses within the big picture, so you can see exactly how these crossovers are working.  Here is an example from the project I'm currently building:

3test_combined_chart.jpg (BTW, that response crosses to a powered sub that I have, which is store-bought.  I have to imagine the crossover at 80 Hz.  Sometimes you just have to picture a result based on what you can reasonably assume.  I'm also assuming a certain amount of SPL from venting both woofers, although I think if I dig a little deeper into this I could find a way to successfully import the box response (from Unibox) into the chart, too.  But I was using this chart primarily for exacting the crossover points.)

By this time you should be up and running and will have a good idea of how to work it from here.  Good luck.

Glad you got that solved!

It takes awhile to get the hang of this, too.  Unibox uses the T/S parameters alone.  But you can export the file you make in Unibox as a .frd file into wherever you store these files, and pick it up in one of the other shared programs.  Unibox will also allow you to import a correction filter, so you can move one to the other program or vise versa.  I've still got plenty of things to learn with these programs, but you know how it is when you want to work up a project:  you find enough to work it out knowing you're still leaving some other things on the table.

Seems to me that if I were looking at someone who felt he needed to completely master any of these programs before he started working on his project, I would be looking at a robot.  Passion takes over, and then you learn as you go.

IIRC, here's how I initially installed these FRD Consortium programs:  After downloading all of the available setup files into My Documents, I went into Power Desk (equivalent of Explorer) and created a new file under Program Files...calling it FRD Consortium.  Then when I unzipped each of those programs, I created sub files with their name under that main file.  I found just a few programs that were easy enough to get right into (I linked the set and associated tutorial early in this thread) and built upon some, not all, of those.  Primarily, I work with Unibox, SPL Tracer and SPL View, and Speaker Workshop.  Some of the others seemed too hard to get the hang of, but I've still got a few years left in me!

If you get good with any of those other ones, post something up in the forum about it.  I'll want to learn what you did.
