In general, high efficiency (low Qts) drivers don't work very well in transmission lines. Transmission lines work best with medium to fairly high Qts woofers (.35 to .90), at least in my experience.High efficiency (low Qts) woofers work best in reflex or (in extreme cases) horn enclosures, so most high-efficiency systems use reflex enclosures.
For more specific recommendations, try your question over at the High Efficiency Asylum. You might also want to try the Pi Speakers Forum, sponsored by Wayne Parham of Pi Speakers. Wayne offers plans and parts kits that will do what you're looking for.
Personally, I think well of the Eminence Delta-Lite woofers. If it were me, I'd use the APT-200 tweeter instead of the APT-80. But please recognize that crossover design is the heart and soul of speaker design, and that it's also what separates the men from the boys. Consider using a driver combination for which a tried and proven crossover design is already available.
Best of luck with your project!
