George Augspurger has graciously allowed me to publish a download of his Transmission line speaker modelling program.

It is published here for download for the benefit of loudspeaker building enthusiasts and designers. Unzip this file and then run the TLwrx3.2.exe program directly. No installer is required.

I have personally designed built and measured five TL designs using George Augspurger’s model and that the designs measure as predicted.

I am very much indebted to George Augspurger for allowing publication of this TL design model for the benefit of all.
