Jeff Bagby Passive Crossover Designer Software Driver Than CanThe design tool has now been expanded to include a box model, an impedance modeler, and a full active crossover design section for each driver than can be used along with the passive crossover features if desired.
In addition to these features dozens of textbook crossover, electrical, and acoustical calculator tools are included as well. One is optimized for Excel 97 - 2003, and the other is optimized for Excel 2007 - 2010. In both cases Analysis Toolpak must be installed and macros must be active for the program to function. This spreadsheet will produce the frequency, phase and impedance response of 2 way, 2.5 Way standard and cascaded versions, and 3 way parallel systems, as well as 2 way series, 2.5 combined seriesparallel designs, and can even be used to design 3 way series networks. It is designed to work with actual driver frequency and impedance data in the form of.frd and.zmazda files which can be imported into the program. It makes use of full x,y,z geometric location of the individual drive units and gives you a movable listening axis, both vertical and horizontal which will allow you to see the driver summation at almost any point in the front hemisphere of the speaker. This model now includes driver directivity, so off-axis simulations will also include directivity response variations as well. This proprietary tool offers very accurate simulations of the summed and individual drivers response at various axial locations. The program has individual sections for woofer, tweeter, and midrange circuits, each with SPL and Impedance charts, as well as System charts that show summed SPL response, approximated power response, phase response, system impedance, and crossover transfer functions. There is a section for system input impedance equalization also. Other features include - options for two woofers, or two midranges, and either wired in series or parallel, automatic calculation of L-Pads, Zobels and series RLC compensation circuits at the click of a button, user selectable built-in or imported Target responses that are overlaid with the drivers response in each section. And all crossover values can be continuously changed via spinners with the response will changing in real-time on the charts, allowing for quick curve-fitting of the response or impedance curves. As mentioned above, the program includes an accurate box design tool with the ability to model the response of both vented and sealed systems. This add-in includes a unique and proprietary impedance modeler that will accurately model the impedance of the woofer in the box used and allow you to use this impedance curve in the crossover design section if desired. In addition, an active crossover section is included that contains high and low pass slopes up to eighth order, five band parametric equalizer (for each section), Linkwitz Transform, and level and delay adjustments. This section can be used with the box model to design subwoofers using active EQ and filters. The program includes the ability to save out all individual driver, crossover (active or passive), and system SPL and Impedance responses to frd and zma files that can be used in other software. It has the ability to print or save charts, and a special system summary print-out page for your project. Included are Pop-up parts layout schematics for each crossover section. And finally, it also contains the ability to save all session data to very small files that can be imported again later thereby resetting all settings in the file to match the previous session or project. Changes for Passive Crossover Designer Version 7.0 The new open view of the file will show column and row headers, sheet tabs, and formula bar. Jeff Bagby Passive Crossover Designer Software Full View ButtonThe 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. 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.
