This is the holy grail. This worksheet allows you to model a straight, tapered, or expanding transmission line. Input parameters include: : The models solved equivalent circuits to predict

Most standard modeling software (like WinISD) uses "Lumped Parameter" modeling—treating the box as a spring with a single pressure. MJK’s worksheets use . helping designers manage the "dipole peak."

Performance measurements of built speakers often correlate extremely well with MJK’s simulation results.

Perhaps his most famous contribution, these worksheets modeled the complex roll-off and floor reflections of speakers without enclosures, helping designers manage the "dipole peak."
