Advanced Engineering Simulation Software

Simulation software for speaker design has been around since the 1970s. With the introduction of the IBM PC and DOS operating system in the early 1980s, Thiele-Small (T-S) simulation software for enclosure design became a must-have for speaker system designers. For the most sophisticated design efforts, there are now magnetic circuit design software and finite element analysis (FEA) cone and thermal prediction simulation software. This article was originally published in Voice Coil, March 2017.
