I'm using WinISD where I can search for parameters that I'm looking for.
Only thing is that software is searching for EXACT values, while as I understand Thiele-Small parameters can be within some values.
If for example left speaker has blown but right is OK, measure the right one. If both are blown or you can't measure, look for a model number on the drive unit and get busy wth Google. If you know who makes the drive unit it should be easy to contact them. Even the whole speaker maker might be tell you the parameters.
