Speaker Modeling Program

Revision date: December 18, 2023

This is a proof-of-concept that I wrote to teach myself JavaScript. It's not intended for serious design work. However, it uses the basic speaker modeling formulas that I've derived and tested in other programs.

You need to turn on JavaScript in your browser to see anything here. If you're paranoid, you can look at the page source to make sure that everything is tame before turning on JavaScript. This program uses Flot, an open source plotting library for JavaScript. You can find out more at: www.flotcharts.org. I'm using Flot in its entirety with no changes.

How did you get here?

  1. You entered a short URL (no parameters such as Fs, etc.) or clicked on a link. This means you're looking at the defaults for the program, my little Eminence 2512-ii box. You can enter your own Thiele-Small and box parameters, and start modeling right away.
  2. You entered a long URL (lots of parameters) or clicked on such a link. This means you're looking at a driver model or box design that somebody has shared (or are using one of my library drivers). You can look at the model or change it and see what happens.
A quick note about the Pe parameter. The program doesn't use it. Instead, the program uses the Amplifier Power parameter for the excursion and port air speed graphs. This lets you figure out how your speaker will perform for your amplifier.
