The "Piega", Master, "Line-Source" 2 and 3 speaker models. What is it? And what is it not?

This company calls this a, "Line-Source" speaker. Made so- "Apparently", because it has "4", of their special, "Line-Source drivers" inside the enclosure. which they say is a "Di-pole".
This as I see it is a, "Point Source" speaker. "Possibly", even a Dipole speaker, but I would think of it more as a "Mid-range, rear- radiating speaker" and not a true dipole. 
It is a "Line Array", (I guess?), because there are four transducers in a row vertically. "Plus another two woofers and two tweeters". But according to them, "Any" of their speakers is a true, "Line Source" as long as they install one of their, "Line source, transducers"?!
I did NOT know such a thing existed! Or "Could", exist. At least not at this time with current materials and technology. 
Does anyone know anything about these? Any experience with these speakers?
Does anyone else notice what I do?
