Introducing the Active Crossover Designer (ACD) by Charlie Laub. Based on a excel file loaded with all the equations required to evaluate the optimal filter for your crossver, the ACD tools is a strongly recommended tool for all speaker designers.
The conceptual approach for these tools has been to create an "open" platform using commonly available spreadsheet tools that many DIY hobbyists are familiar with. Because all of the calculations are done using spreadsheet formulas that are all visible and accessible, the tools are fully extensible. The user can change any and everything, or add on new functionality, plots, and so on. Some examples of useful add-ons for the CORE TOOLS are provided in the EXTENSIONS section. Currently, only an Excel version is available, however, an OpenOffice Calc version has been developed in parallel and the release is coming (eventually). ACD is written for Excel version 2003 and later, and requires the Analysis Toolpak.
ACD tools come up with a fully featured start up guide and user manual. The following pictures are just samples of the type of simulations you can expect out of ACD tools.
The whole miniDSP team would like to thank Charlie Laub, Author of ACD Tools, for designing such a useful tool! All credits goes to Charlie for putting together this nice tool. If you want to thank him yourself, remember to fire a small email to him or share your experience on our Forum.
Enjoying ACD? Such tools take time to come up and be developed over time but most important, it takes a very generous mind to offer them free of charge! So please make sure to remember to support ACD with a donation. All profits go to Charlie and besides showing your support for his work, It will help his future enhancement of the ACD tools.
