Response peak unibox11/30/2023 ![]() ![]() But I was using this chart primarily for exacting the crossover points.)īy this time you should be up and running and will have a good idea of how to work it from here. 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. Sometimes you just have to picture a result based on what you can reasonably assume. I have to imagine the crossover at 80 Hz. Here is an example from the project I'm currently building:ģtest_combined_chart.jpg (BTW, that response crosses to a powered sub that I have, which is store-bought. 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. The 'auto-overview chart' is a third one that shows up, and you'll find that the chart is a valuable working tool. These will show the freq response and impedance of your project. If you have all the blocks checked, some files will appear in the left column. Name this project, and go back up to the toolbar and choose 'Network', 'Calculate response'. Also, right click and choose 'Properties'.check the blocks under the 'General' tab. 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. With supplied power and drivers, it's now a matter of designing the crossover. Insert the drivers into the network by choosing 'Network', 'Insert', and pick the drivers you have entered into the database. Everything in the network is built onto that source. One side is positive and the other is negative, and it represents the power supply. You'll get a screen opened with nothing but a symbol that reads "Source". I use SPL Trace to make these files from manufacturer's published graphs like these. ![]() ![]() zma files (freq response and impedance) into your network. Input the drivers and their parameters that you want to work with. Everything you add will be installed in this network. But to start, choose 'Resource', then 'New'.then choose 'Network'. You'll eventually see those tools in the toolbar change to different things depending on what you have working at the moment. The top drop-down toolbar is where you start, add something, anything. Here's a few things to get a project started: 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. Speaker Workshop has a Help file that would make a small book. I must have my settings alright in Zone Alarm because I click on "enable macros" and everything is okay. As I understand it, macros in general are sometimes used maliciously. You'll probably have to change a security setting in your security software. 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.Īfter you've started a project, use the 'Save' function under "Design Database" to keep your woofer on file. Make sure that is set to "Single drive unit" as you input supplied parameters (although it should come up that way by default). If something is off, there will be a correction you can make in the inputs to get it right.Īnd this: there's a box over in the right column that says "Drive Unit Configuration". In other words, watch the middle column values that the program calculates to see if anything appears far off from the given data. 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. 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. Sometimes you'll find one of those missing in the supplied data often it's Sd. The top left set of boxes under "Drive Unit Parameters" allows you to fill in several T/S parameters. 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. That's what I do.I've never needed those values. ![]()
