@chorus first step, head over to the DIY forums, very limited experience here.
IF you are an extra-hands-on type person and normally build things yourself at home, with good plan/design/specs, go DIY and build it yourself. Madisound sources specs from the driver manufacturers, which helps. Check out Troels too, http://www.troelsgravesen.dk/Diy_Loudspeaker_Projects.htm
If wood making is not for you, source a local cabinet woodworking shop to build you furniture grade enclosures, and wind up with much better parts, better results, better enclosures, at half the cost of new. Buy all top the shelf drivers if you proceed. All new parts! You won't look back with high quality diy keeper-speakers, and less likely to resale them later. Can be very rewarding. Best of luck.
