Default DIY speaker driver?

Don't know if you guys can help or not....

My son wants to build a speaker driver for a physics project.

I have built many speaker systems over the years. But I have never built a driver.

Anyone done this - whether as an experiment or more seriously?

Any basic parameters such as coil turns, wire gauge, and appropriate magnets?

Any help appreciated.

Do a search for a post by a person named Vikash. He had a webpage where he tried this.

I posted a spreadsheet in that thread that can be used for driver design. It transforms turns of wire, mass, etc into T/S parameters... It doesn't do the magnetic portion though, You need to use a program like FEMM to model the magnetic system, then you can Enter B (gap magnetic flux) into the spreadsheet.

Have fun!

Here are some useful formulas:
Bl is B*l, Flux*length of wire in the field. More valid for achieving a correct damping is B*m, m=mass of copper in the field, compared to the whole moving mass.
