“Based on the work of M.J.K. He built the math. I just woke it up.”

Do you prefer a standard or a Mass-Loaded (ML-TL) design?

I can provide the specific geometric formulas and driver placement rules derived from King's original research to help guide your design. Share public link martin j king mathcad worksheets

The acoustic interaction between the driver and the terminus (port). Why Mathcad?

: Enter the Thiele-Small (T/S) parameters ( Fscap F sub s Vascap V sub a s end-sub Qtscap Q sub t s end-sub , etc.) for your specific driver. “Based on the work of M

These were the flagship sheets of the collection. They allowed users to input the physical dimensions of a transmission line cabinet alongside the Thiele-Small parameters of a chosen driver. The sheet calculated the system's frequency response, electrical impedance, and the combined acoustic output of both the driver cone and the open terminus (port). 2. Bass Reflex and Ported Alignment

: Define the length of the line, cross-sectional areas ( S0cap S sub 0 for the start, SLcap S sub cap L I can provide the specific geometric formulas and

What you want to build (e.g., ML-TL, Open Baffle, standard ported) The driver model you intend to use

The sheet generates comprehensive performance curves, including:
