Martin J King Mathcad Worksheets |best| Guide

Before King’s worksheets, building a transmission line speaker involved guesswork, intuition, and "golden ratio" formulas. These older methods often resulted in boomy bass or severe mid-bass cancellation. King’s worksheets introduced several paradigm shifts:

Pipes with a cross-sectional area that changes along their length. Limitations and Considerations

While MJK's worksheets remain a gold standard for TL design, other tools and programs have emerged. The modern DIY designer is likely to encounter: martin j king mathcad worksheets

However, the legacy persists. While you cannot always get the raw .xmcd or .mcd files directly from his main landing page, the community has preserved them via the and dedicated DIY audio forums (DIYAudio.com, AudioKarma, The Loudspeaker Building & Design Facebook groups).

Martin J. King is a retired mechanical engineer with a background in vibration analysis. In the early 2000s, he turned his analytical eye toward a long-standing problem in audio: the transmission line (TL) loudspeaker. Unlike ported boxes (bass reflex) or sealed enclosures, transmission lines were considered "black art"—tricky to model, difficult to build, and heavily reliant on trial and error. Martin J

If you are building a set of floor-standing towers, do not guess the length of the pipe. Find a copy of the ML-TL worksheet, model your driver, and build a speaker that Martin J. King himself would be proud of.

As with any simulation, real-world factors like panel resonances or irregular room interactions are not included. Where to Find Martin J. King Worksheets
