Speaker Box Filter Designer

Speaker Box Filter Designer is a lightweight digital tool created to help you perform calculations for components needed to build passive audio filters.

Simple interface but not for everyone

It’s a proof free fact that Speaker Box Filter Designer displays a user-friendly interface and you can convince yourself of this from the first time you run it. It comes with a basic GUI which offers you quick access to all its options and features.
From the main window you are able to choose the filter type and order, as well as perform calculations for the coil and passive filter. Speaker Box Filter Designer may be easy to work with but to properly use it you need to know what you’re doing because it is a tool which offers very little assistance in explaining technical terms.
The application allows you to calculate filters of 2-way and 3-way orders and the only help you get is a series of images that show you the layout of the circuits. The rest depends on your knowledge of filters and how they are built.

Input parameters and get results in a second

Working with Speaker Box Filter Designer is anything but complicated because all you have to do is fill in the appropriate data that is required and with a click on the ‘Calculate’ button, you're done.
The application uses the Harold Wheeler formula for multi layer air core inductance and also relies on the Bessel and Buterworth filter types for the second and third order.

Quickly design passive filters

To sum things up, Speaker Box Filter Designer might not be the most practical of tools but it does provide a solid base for passive filter design as long as you’re familiar with the entire process.
