Yo speaker seekers:
Focal also makes excellent, but very expensive raw drivers that are available in U. S. from Zalytron in Mineola, New York. They make an excellent MTM kit using Focal drivers that comes in about $2,000 by the time you are through. It's way over my head, but...http://www.zalytron.com/
I have not used Focal drivers, but I hear they are in a similar class with Dynaudio drivers like mine, so I expect that the finished speaker systems will also be very good.
And good luck from that cheap old box builder,
