I know very little about the subject, but in my travels around the web looking at designs, I have never seen one like this one.
What will this do that the normal "building block" parallel types do not?

The only way you will know is to build one and listen, if you can get it right ;-)

1st order are easier for a beginner, but have to have suitable drivers.

Pretty sure it's a funky way of introducing a cauer-elliptic filter...
