Default Audax Centre channel crossover for midrange

Hi,
I'm building the Audax centre channel speaker following the plans shown here, http://www.madisound.com/Audax%20Kit...us_ht07a.shtml

I've just finished the midrange crossover following the layout as shown here, Click the image to open in full size.

Now I've just realise that the schematics has the C2 and L2 in reverse order are the one in the layout, as shown here, Click the image to open in full size.

Do I need to reverse the order of C2 and L2 so it follows the schematics or I just leave it as it is?

IMHO it doesn't change anything that on the midrange the highpass is placed before or after lowpass.
It looks like a 1st order highpass and a 3rd order lowpass.

...But wait for confirmation.

Seconded.

If you haven't built the box yet, think about moving the drivers closer together and adding a little more bracing, both worthwhile improvements.

I'd be tempted to stick with the original plans not move drivers. Joe D'Appolito really knows what he's doing and he may have spaced them like that to achieve a certain dispersion pattern at the crossover frequency.

He quite possibly did, but when I built the box as specified, low mids were a little directional.

Probably ok if you live in a huge house...

So it doesn't matter if C2 or L2 comes first. Than I'll leave of the crossover as it is, as per the picture layout.

Many thanks for clearing my doubt.
