Martin J. King's Projects [Editor: Martin King's projects document his on-going development of a computer model to aid in the design of speakers designs using Quarter Wave resonances to augment the output in the bass. So far he has demonstrated a Transmission Line and a Tapered Quarter Wave Tube (aka Voigt Pipe). His software model is freely available for download so that you can use it to design your own TL or TQWT. Martin enjoys all the feedback he can get on designs implemented based on his software so that he can continue to improve it] 07/30/02 Note: Martin now has his own web-site at www.quarter-wave.com with the most up-to-date stuff and i will be modifying this section content that is more of a commentary that is complementary to Martin's site. Focal TL -- Derivation and Correlation of a Viscous Damping Model Used in the Design of a Transmission Line Loudspeaker System. This covers the upgrades to the MathCad Transmission Line Computer Model.
