Buy a Focal-based design from the likes of Zalytron before their supply of OEM drivers runs out.
I recently built monitors using the Audiom TD-5 tweeter (the ones used in the Grand Utopias before the Beryllium driver). The Zalytron cabinets are veneered 1.5" MDF and rock-solid, with precision baffle cutouts for the drivers. Though I don't have cash for the cabinets/crossovers quite yet, I just bought a pair of Focal 10W6452 woofers for the bass units out of concern these great drivers will soon become extinct in the OEM world...
With only the most basic soldering skills, Minwax stain, a glue gun and screwdrivers you can have a truly high end Focal system at a fraction of retail.
