I have received the drivers, and I am impressed, the build quality is excellent.
I thought at first they sounded harsh and very bass light, so I hooked them up to an old aurex transistor amp, and played the prodigy on repeat for about 8 hours as loud as possible
they have loosened right up and they can easily reach a decent spl level at about 3/4 volume with my amps, with decent bass, not earth shaking but it is there, and it sounds very controlled and tight, better than most stand mounters I have heard.
they still sounded a bit lacking in the treble department, so I wouldn't use them without a supertweeter, but they pretty much do what they say they do, amazing for the price I think.
I cut the dust caps out after a few hours and added the phase plugs, they make a subtle difference, they add to the imaging and the bass seems tighter, so worth a try if you are thinking of using them.
all in all I am happy with them, but I couldn't recommend them fully as a single driver solution. so unless you are prepared to use a very large cabinet or add a sub then you will loose bass and some treble, but do sound pretty good still.
I recommend using supertweeters with a 1 uf cap to start with.
so no they are not full range but pretty close,(the bass goes pretty low surprisingly) and sounds better than my old speakers, 3way aerogel aurex drivers in a fairly large sealed box.
there is only a 1uf cap for a crossover, so I have nearly achieved my goal of high sensitivity no crossover, and simplicity.
