audioXpress September 2024 Is Live. Make Smart Audio Moves!

There's a lot of knowledge in audioXpress September 2024. There's a residential installation and home theater Market Update, and a review of the Dayton Audio iMM-6C USB-C Test Microphone. George Ntanavaras shares what he learned using AKABAK simulation software, and Charlie Laub explains all about Derived from Elliptic crossover filters. Read Jan Didden's interview with Joachim Gerhard discussing Low Noise Phono Stages, and learn how to build a Moving-Coil Phono Preamp designed by Sam Dulaney. And much more.

Dinaburg Technology developed a unique patented integral coaxial speaker cone approach that features the advantages of a passive radiator in a small volume and takes advantage of a back wave from the loudspeaker’s diaphragm to optimize the passive radiator’s response and the off-axis performance of the active driver. The advantages are clearly audible, and this article dives into the mathematical simulation, and integrating the mechanical, acoustical, and electrical simulations.

Modeling and Simulation and Measurement systems evolved significantly in the past decade. Important progress is now bridging the gap between COMSOL simulation and Klippel measurement data, Roger Shively reports after returning from Orlando, FL, where we attended another edition of the ALTI Expo & Conference (June 11-13, 2023). This article summarizes the content covered in a very important session as part of the APDA-ALTI Education Symposium 2023.
