Default Testing Thiel Small parameters.

Just a suggestion for a WIKI.
could someone(team) write a WIKI for the procedure to test a speaker unit to determine the Thiel Small parameters?
regards Andrew T.

have you looked at Speaker Workshop?

Testing Thiel Small parameters.
I am working on a fully detailed procedure suitable for beginners (i.e. no maths required) and experts alike, to get accurate, repeatable results with no special equipment other than a PC with sound card + amp and ac millivolt meter. No requirement to build any jigs or setups either.

Parameters covered: Fs, Qes, Qms, Qts, Vas, Mms and Cms. Also how to accurately measure Fb and Ql.

I will be putting the guide on my website after the weekend. It is 99% done, just needs the website bit sorting and a spreadsheet tidying up. If you want to be a beta tester send me a message
