Name your woofer in this box, check the 'auto-calculate' checkbox, then pick the tab at the top titled 'Parameters'. In fact, if you want to get to know more about them here is a guide.
A definition list here, and good info here. Parameters affect the value of other parameters. WinISD wants to calculate some of them, or if it doesn't actually do it itself, it wants what you enter to exactly match its own calculation. The key is to enter as few parameters as possible at first until you see what WinISD doesn't calculate.
Get that? Don't put all the parameters in the blocks! Let's try to avoid that first dreaded error box! If you enter a number in any block, it will be the color green. If the program calculates a value, it will appear in blue. To start, you can enter three values in the top section and actually have enough for a minimal workup.. Qts, Fs and Vas. But if you have more parameters than that, and you should, don't enter any numbers yet. Scroll down the page until you see it.
Follow those guidelines every time you enter new data. Use the 'tab' key on your keyboard to jump to the next block when you enter parameters, or to skip past blocks.
I've learned to jump past blocks several times while entering data just to see if the program wants to calculate something else from what I've entered. You'll notice that when you enter, say, Vas You can easily change it in WinISD. Place your mouse cursor over the unit, it will change to a hand, and click through until liters l is displayed. Now enter your Vas in liters.
There is more about these special tools in the section "A look at your working tools". What do I do? This is the dreaded error box that puts so many users off. It gives you rows of parameters with no information at all about what to do with it. I can guarantee if you input a complete list of manufacturer's parameters into the program, you will get the error box.
The rows of parameters, separated by commas, are the values that are calculated amongst themselves. This is avoided if you follow the guidelines for the order in which to enter parameters. But if you do get this box, you will need to go back to the driver editor and wipe out one of the offending values.
If you're not sure which one out of the row to turn into a zero, just pick one. In the case of the Qms, Qes, Qts error, you would go back and highlight Qts, then enter 0. Once you tab past it, you will see the calculated value appear. Compare it to the value you entered, and you'll most likely find that either yours was not entered to the proper decimal place or was.
You have just overcome the biggest hurdle. You are already on your way to mastering the program. WinISD has begun looking at your woofer from the time you entered the first set of parameters. Give it something to calculate and that is what it will do. In fact, it's a whole bunch of calculators all tied up into one attractive package. It has already formed a picture of your woofer by the time it got just a portion of those parameters, and it changes the picture with every change you make in the input.
By this time, you wil have saved and named your project. The parameters gave WinISD enough information to make a call on how much airspace this woofer needs to get the flattest response. Remember the red line in the chart? That is flat, so a response drawn along this line is the flattest it can be. It has to drop off somewhere, though, and where it does primarily depends on how much air the woofer has behind it, in the box. Car audio is rife with compromise.
You have only a defined area in which to build a box, and weight is always a consideration As you look at the 'New project It has already calculated the EBP see it shown? Then it made the most logical conclusion of what type of alignment Q based on the flatness of the response. This is a tool, not a designer. If you want SPL and a high peak, you can change it however you want. The program doesn't know you're putting it in a car or how much space you have.
This is a default evaluation defined by the parameters. It sees that the flattest response is gotten by using 35 cu ft so well, there it is! But you have to keep this in mind: WinISD doesn't design your box; you do. It provides you with the tools. Change the air volume to fit the space you have and go from there.
This sub is best suited for sealed EBP of In other words, as SQ as possible. Hover your mouse at the bottom right corner of the screen to make the 'expand' icon appear, click it, and the image will appear full.
With a sealed woofer, take notice of the box labelled 'Qtc' in the inset dialogue box. If you were to highlight, then change the air volume to try several different volumes, you would see this Q change with every change you make. The value of. Such is the real world with car audio. You should use the program to look at the response in 1 cu ft and see what it tells you: sealed1winisd. Look at low end response by looking at the lower Hz part of the chart, specifically at where the line curves across the purple F3 line.
That point would be considered the low end of your sub's response because at that point the power is only half of what it is at 0.
Look at the Qtc box; the Q has risen to. No, you find a way to get two cubic feet. The curved line represents the sound from your sub in that amount of airspace. When the line peaks above the flat 0 line, it tells you that there will be more power going to those frequencies within the peak than there will be elsewhere. When the line dips below flat, less power is produced. The peakier the response, the higher the Q, and the less musical the overall sound.
There are times, though, when a peaked response is preferred, namely when competing in SPL competitions. When max power is within the range of the vehicle's resonant frequency, the sub may prove to be louder because of that marriage of sound in that range. But you wouldn't use this woofer for SPL comps, you'd choose another. The one tool you are already familiar with is the mouse and keyboard of your PC.
You can change the number in any of the boxes throughout the program by highlighting with the cursor and then typing in the value of your choice. In the example above, I changed 1. The cursor also acts to change the value of unit measurements, such as from cubic feet to liters as we did earlier. This is a big benefit of WinISD in that you don't have to have a separate conversion calculator on hand as you are working within the program.
But hey, here's a great one because I'm just feeling generous. Looking at how you can change units with the mouse, let's go back to the charts. You can change the charts considerably. Right click on the chart and a small box will appear, choose 'Options'. Another box appears and allows you to change the start, end or unit type in any of the charts.
Now that you're becoming comfortable with making changes and seeing that nothing has blown up, you can start fiddling with the response from your woofer.
Change the airspace to several different volumes, watch the chart for the response, and note the Q. Bring your same woofer up again on the same chart by clicking 'New project', select your driver it's now on the list , and click through the "New project Change the color of the response by placing the cursor atop the colored bar in the box and click to select another color for the second response line.
Possibly the greatest value of this program is that it will enable you to model a vented box. Some woofers are best as sealed, others are best as vented. The EBP, you remember, appears in the center of the 'New project' box when you first bring up the new project. The Kappa sub we were looking at above had a Higher EBP's generally call for a vented box. The program determines the best box using this EBP value by default. But as a working tool, the program allows you to change to whichever you want.
Here is an ID sub from the program's database: ventedwinisd. Most of the reason this sub "looks" like it sounds so good is due to its engineering; the rest is due to providing just the right mix of airspace and port airspace to the enclosure. In the pic, you can see the vent diameter of 4" and vent length of 32".
My box is only 18". Now what? This is where you work the program to get the best response for what space you have available. This box is also specified to be 2. If you don't have that much space available you have to make a change there as well. By default, WinISD will calculate a vent opening at 4. This is where almost every user of the program will have to make a change. A larger diameter vent will equate to a longer length, and a smaller diameter vent will call for a shorter length.
