One thing I look for in a speaker is a waveguide that's at least as wide as the driver under it.
That geometry makes a directivity match in the crossover region more likely. On that basis, the 12" eD is interesting, the 6" eD and CHT less so.
Don't like the ports, though. IMO mains should be closed box, to make subwoofer integration less of a hassle. And front ports contribute to diffraction.
