Hi,
Do some number crunching also, in a spreadsheet like Excel, because the xover parts might cost as much as the price for a driver. This is much worse if you go 3 way and up. If you get the parts from Wayne you have one problem solved.The wood for the boxes, with out paint and handwork, can also vary from 1 to 10 fold depending of the quality. You end-up with one much better vue of the final price if you put it all together. Now I understand why the speakers from good factories come with bad xover parts.
Regards
