Or you can import two completely different drivers with different frd and zma file if desired as well.)Ĭhanged the Z-offset convention to be negative if the acoustic center is "behind" the zero plane, as in the case of the woofer's acoustic center being behind the tweeter. This allows you to import two different diffraction responses for drivers in an MTM, for example. The ability to import the second set of data is under the selection for two woofers and two midranges and is only an option to be used as desired. (Note: If, however, you wish to model two woofers or two midranges and do not want to import a second set of data, that is OK, as the program will automatically use the original data as it did before as a default.

The buttons to access these layouts are in each driver section button grouping.Īdded the ability to import second woofer and second midrange frequency response and impedance data files, so five different drivers can be imported if desired.
There are no longer additional file folders that need to accompany the program to view these layouts. This page was causing too many issues with screen updating in Excel 2007 and was being used by too few users to justify maintaining it.īuilt all of the old schematics and crossover layout pictures into the program rather than external and accessible through hyperlinks. (Files saved in this way will about 5mB in size)Ĭlosing the file will no longer shut down the Excel application. When the file is reopened, the project will be exactly as it was when filed. The spreadsheet will compress and save containing all data including frd and zma file data. Simply click on "save as" in Excel, and give it a new name for your project. This version offers the ability to save the file with all data loaded under a new name and be able to reopen the file with the project intact. The ability to switch to a full-screen view with these features hidden is still present by clicking the "Full View" button under the Chart Manager. The new open view of the file will show column and row headers, sheet tabs, and formula bar. Special thanks to Charlie, as always, for hosting the files.Ĭhanges for Passive Crossover Designer Version 7.0 I would really appreciate it if those of you who post on other forums would link this announcement for me. Missing this will change your results considerably.Īs before, there are versions optimized for Excel 97-2003 and for Excel 2007-2010 available. Please make special note of the Z axis change in blue.

Some will go gaa-gaa over the fact that I am now allowing you to save the file under a new name with all data, frd, and zma file intact. Some of you will love the fact that you can see sheet tabs, column headers, and be able to unprotect the main page and change chart settings on your own (but be careful not to mess something else up, you're on your own there). I got perturbed at Microsoft for the way they changed things in Excel 2007, so in order to make the program function more smoothly I decided to make it work more like an Excel file and less like a "program", although it still does all that is did before. I did not change the electrical voltage divider and circuit within the program this time, but dramatically changed how the program functions in Excel. Good afternoon! I am pleased to announce that Passive Crossover Designer 7.0 (PCD 7) is now available.
